In some countries, there is a free flow of information about infrastructure, agriculture, and industry, whereas in other countries, this information is controlled by a small elite. In the latter countries, the vast majority of the population is denied vital information about factors that determine their welfare. Thus, these countries are likely to experience more frequent economic crises than other countries do.

The conclusion follows logically if which one of the following is assumed?

In 1892 the Sierra Club was formed. In 1908 an area of coastal redwood trees north of San Francisco was established as Muir Woods National Monument. In the Sierra Nevada mountains, a walking trail from Yosemite Valley to Mount Whitney was dedicated in 1938. It is called John Muir Trail.
John Muir was born in 1838 in Scotland. His family name means "moor," which is a meadow full of flowers and animals. John loved nature from the time he was small. He also liked to climb rocky cliffs and walls.
When John was eleven, his family moved to the United States and settled in Wisconsin. John was good

with tools and soon became an inventor. He first invented a model of a sawmill. Later he invented an alarm clock that would cause the sleeping person to be tipped out of bed when the timer sounded. Muir left home at an early age. He took a thousand-mile walk south to the Gulf of Mexico in 1867and 1868. Then he sailed for San Francisco. The city was too noisy and crowded for Muir, so he headed inland for the Sierra Nevadas.
When Muir discovered the Yosemite Valley in the Sierra Nevadas, it was as if he had come home. He loved the mountains, the wildlife, and the trees. He climbed the mountains and even climbed trees during thunderstorms in order to get closer to the wind. He put forth the theory in the late 1860's that the Yosemite Valley had been formed through the action of glaciers. People ridiculed him. Not until 1930 was Muir's theory proven correct. Muir began to write articles about the Yosemite Valley to tell readers about its beauty. His writing also warned people that Yosemite was in danger from timber mining and sheep ranching interests. In 1901 Theodore Roosevelt became president of the United States. He was interested in conservation. Muir took the president through Yosemite, and Roosevelt helped get legislation passed to create Yosemite National Park in 1906. Although Muir won many conservation battles, he lost a major one.
He fought to save the Hetch Valley, which people wanted to dam in order to provide water for San Francisco. In the late 1913 a bill was signed to dam the valley. Muir died in 1914. Some people say losing the fight to protect the valley killed Muir.

When did Muir invent a unique form of alarm clock?

What does the word patent mean to you? Does it strike you as being something rather remote from your interests? If it does, stop and think a moment about some of the commonplace things that you use every day, objects that you take for granted as part of the world around you. The telephone, radio, television, the automobile, and the thousand and one other things (even the humble safety pin) that enrich our lives today once existed only as ideas in the minds of men. If it had not been possible to patent their ideas and thus protect them against copying by others, these inventions might never have been fully developed to serve mankind. If there were no patent protection there would be little incentive to invent and innovate, for once the details of an invention became known, hordes of imitators who did not share the inventor's risks and expenses might well flood the market with their copies of his product and reap much of the benefit of his efforts. The technological progress that has made America great would wither rapidly under conditions such as these. The fundamental principles in the US. patent structure came from England. During the glorious reign of Queen Elizabeth I in England, the expanding technology was furthered by the granting of exclusive manufacturing and selling privileges to citizens who had invented new processes or tools- a step that did much to encourage creativity. Later, when critics argued that giving monopoly rights to one person infringed on the rights of others, an important principle was added to the patent structure: The Lord Chief Justice of England stated that society had everything to gain and nothing to lose by granting exclusive privileges to an inventor, because a patent for an invention was granted for something new that society never had before. Another basic principle was brought into law because certain influential people in England had managed to obtain monopoly control over such age-old products as salt, and had begun charging as much as the traffic would bear. The public outcry became so great that the government was forced to decree that monopoly rights could be awarded only to those who created or introduced something really unique. These principles are the mainstays of our modern patent system in the United

States. In colonial times patent law was left up to the separate states. The inconsistency, confusion, and unfairness that resulted clearly indicated the need for a uniform patent law, and the men who drew up the Constitution incorporated one. George Washington signed the first patent law on April 10, 1790, and less than four months later the first patent was issued to a man named Samuel Hopkins for a chemical process, an improved method of making potash for use in soapmaking. In 1936 the Patent Office was established as a separate bureau. From the staff of eight that it maintained during its first year of operation it has grown into an organization of over 2500 people handling more than 1600 patent applications and granting over 1000 every week. The Patent Office in Washington, DC., is the world's largest library of scientific and technical data, and this treasure trove of information is open for public inspection. In addition to more than 3 million U. S. patents, it houses more than 7 million foreign patents and thousands of volumes of technical literature. Abraham Lincoln patented a device to lift steam vessels over river shoals, Mark Twain developed a self-pasting scrapbook, and millionaire Cornelius Vanderbilt invented a shoe-shine kit. A patent may be granted for any new and useful process, machine, article of manufacture, or composition of
matter (a chemical compound or combinations of chemical compounds), or any distinct and new variety; of
plant, including certain mutants and hybrids. The patent system has also helped to boost the wages of the American worker to an unprecedented level; he can produce more and earn more with the computer,
adding machines, drill press or lathe. Patented inventions also help keep prices down by increasing manufacturing efficiency and by stimulating the competition that is the foundation of our free enterprise system.
The decades of history have disclosed little need for modification of the patent structure.
Our patent laws, like the Constitution from which they grew, have stood the test of time well. They encouraged the creative processes, brought untold benefits to society as a whole and enabled American technology to outstrip that of the rest of the civilized world.

What is the main idea of this passage?

Is it necessary for defense lawyers to believe that the clients they defend are innocent of the charges against them? Some legal scholars hold that lawyers* sole obligation is to provide the best defense they are capable of, claiming that in democratic societies all people accused of crimes are entitled to the best possible legal representation. They argue that lawyers have no right to judge defendants because it is the job of the courts to determine guilt or innocence and the job of the lawyer to represent the defendant before the court. They believe that the lawyer's responsibility is to state those facts that will assist each client's case, construct sound arguments based on these facts, and identify flaws in the arguments of opposing counsel. According to these scholars, the lawyer's role is not to express or act on personal opinions but to act as an advocate, saying only what defendants would say if they possessed the proper training or resources with which to represent themselves.

But such a position overlooks the fact that the defense lawyer's obligation is twofold: to the defendant, certainly, but no less so to the court and, by extension, to society. For this reason, lawyers, great as their obligation to defendants is, should not, as officers of the court, present to the court assertions that they know to be false. But by the same principle, lawyers who are convinced that their clients are guilty should not undertake to demonstrate their innocence. Guilty defendants should not be entitled to false or insincere representation. When lawyers know with certainty that a defendant is guilty, it is their duty not to deny this.
Rather, they should appraise the case as much as possible in their client's favor, after giving due consideration to the facts on the other side, and then present any extenuating circumstances and argue for whatever degree of leniency in sentencing they sincerely believe is warranted. In cases where it is uncertain whether the client is guilty but the lawyer sincerely believes the client may well be innocent, the lawyer should of course try to prove that the client is innocent.

The lawyer's obligation to the court and to society also ultimately benefits the defendant, because the "best defense" can only truly be provided by an advocate who, after a careful analysis of the facts, is convinced of the merits of the case. The fact that every client is entitled to a defense does not mean that defense lawyers should take every case they are offered. Lawyers should not be mere mouthpieces for a defendant but instead advocates for the rights of the defendant given the facts of the case.

According to the passage, the legal scholars mentioned at the end of 1st paragraph believe that it is a defense lawyer's role to be

Always read the meter dials from the right to the left. This procedure is much easier, especially if any of the dial hands are near the zero mark. If the meter has two dials, and one is smaller than the other, it is not imperative to read the smaller dial since it only registers a small amount. Read the dial at the right first. As the dial turns clockwise, always record the figure the pointer has just passed. Read the next dial to the left and record the figure it has just passed. Continue recording the figures on the dials from right to left. When finished, mark off the number of units recorded. Dials on water and gas meters usually indicate the amount each dial records.

When you have finished reading the meter, mark off

The Galapagos Islands are in the Pacific Ocean, off the western coast of South America.
They are a rocky, lonely spot, but they are also one of the most unusual places in the world. One reason is that they are the home of some of the last giant tortoises left on earth. Weighing hundreds of pounds, these tortoises, or land turtles, wander slowly around the rocks and sand of the islands. Strangely, each of these islands has its own particular kinds of tortoises. There are seven different kinds of tortoises on the eight islands, each kind being slightly different from the other. Hundreds of years ago, thousands of tortoises wandered around these islands. However, all that changed when people started landing there.
When people first arrived in 1535, their ships had no refrigerators. This meant that fresh food was always a problem for the sailors on board. The giant tortoises provided a solution to this problem. Ships would anchor off the islands, and crews would row ashore and seize as many tortoises as they could. Once the

animals were aboard the ship, the sailors would roll the tortoises onto their backs. The tortoises were completely helpless once on their backs, so they could only lie there until used for soups and stews.
Almost 100,000 tortoises were carried off in this way. The tortoises faced other problems, too. Soon after the first ships, settlers arrived bringing pigs, goats, donkeys, dogs and cats. All of these animals ruined life for the tortoises.

Donkey and goats ate all the plants that the tortoises usually fed on, while the pigs. Dogs and cats consumed thousands of baby tortoises each year. Within a few years, it was hard to find any tortoise eggs-or even any baby tortoises. By the early 1900s, people began to worry that the last of the tortoises would soon die out. No one, however, seemed to care enough to do anything about the problem. More and more tortoises disappeared, even though sailors no longer needed them for food. For another fifty years, this situation continued. Finally, in the 1950s, scientist decided that something must be done. The first part of their plan was to get rid of as many cats, dogs and other animals as they could. Next, they tried to make sure that more baby tortoises would be born. To do this, they started looking for wild tortoise eggs. They gathered the eggs and put them in safe containers. When the eggs hatched, the scientists raised the tortoises in special pens. Both the eggs and tortoises were numbered so that the scientists knew exactly which kinds of tortoises they had-and which island they came from. Once the tortoises were old enough and big enough to take care of themselves, the scientists took them back to their islands and set them loose. This slow, hard work continues today, and, thanks to it, the number of tortoises is now increasing every year. Perhaps these wonderful animals will not disappear after all.

What happened soon after people brought animals to the islands?

Two mannequins -- 1 and 2 -- will be dressed for display in outfits chosen from ten articles of clothing.
Each article is in exactly one of three colors: navy, red, or yellow. There are three hats -- one in each color;
three jackets -- one in each color; three skirts -- one in each color; and one red tie. Each mannequin wears
exactly one of the hats, one of the jackets, and one of the skirts. Furthermore, their outfits must meet the following restrictions:

Neither mannequin wears all three colors.
Each mannequin wears a hat in a different color from the jacket it wears.
Mannequin 2 wears the navy skirt.
Mannequin 1 wears the tie.

If all four of the red articles of clothing are included in the two mannequins' outfits, which one of the following must be true?

Some types of organisms originated through endosymbiosis, the engulfing of one organism by another so that a part of the former becomes a functioning part of the latter. An unusual nucteomorph, a structure that contains DNA and resembles a cell nucleus, has been discovered within a plant known as a chlorarachniophyte. Two versions of a particular gene have been found in the DNA of this nucleomorph, and one would expect to find only a single version of this gene if the nucleomorph were not the remains of an engulfed organism's nucleus.

Which one of the following is most strongly supported by the information above?

A study of young and middle-aged men in the United States has found that the men whose diet was high in saturated fat also had a high amount of blood cholesterol. In another experiment, when the blood cholesterol level of laboratory rabbits was raised by feeding them exclusively on cholesterol, fat deposits formed in their blood vessels. Similar fat deposits are found in human patients of heart disease. Therefore, to reduce the occurrence of heart disease, people should reduce their dietary consumption of saturated fat.

Each of the following, if true, weakens the above argument EXCEPT:

Conflict had existed between Spain and England since the 1570s. England wanted a share of the wealth that Spain had been taking from the lands it had claimed in the Americas. Elizabeth I, Queen of England, encouraged her staunch admiral of the navy, Sir Francis Drake, to raid Spanish ships and towns. Though these raids were on a small scale, Drake achieved dramatic success, adding gold and silver to England's treasury and diminishing Spain's omnipotence. Religious differences also caused conflict between the two countries. Whereas Spain was Roman Catholic, most of England had become Protestant. King Philip II of Spain wanted to claim the throne and make England a Catholic country again. To satisfy his ambition and also to retaliate against England's theft of his gold and silver, King Philip began to build his fleet of warships, the Armada, in January 1586. Philip intended his fleet to be indestructible. In addition to building new warships, he marshaled one hundred and thirty sailing vessels of all types and recruited more than nineteen thousand robust soldiers and eight thousand sailors. Although some of his ships lacked guns and others lacked ammunition, Philip was convinced that his Armada could withstand any battle with England.

The martial Armada set sail from Lisbon, Portugal, on May 9,1588, but bad weather forced it back to port.
The voyage resumed on July 22 after the weather became more stable. The Spanish fleet met the smaller, faster, and more maneuverable English ships in battle off the coast of Plymouth, England, first on July 31 and again on August 2. The two battles left Spain vulnerable, having lost several ships and with its ammunition depleted. On August 7, while the Armada lay at anchor on the French side of the Strait of Dover, England sent eight burning ships into the midst of the Spanish fleet to set it on fire. Blocked on one side, the Spanish ships could only drift away, their crews in panic and disorder. Before the Armada could regroup, the English attacked again on August 8. Although the Spaniards made a valiant effort to fight back, the fleet suffered extensive damage. During the eight hours of battle, the Armada drifted perilously close to the rocky coastline. At the moment when it seemed that the Spanish ships would be driven onto the English shore, the wind shifted, and the Armada drifted out into the North Sea. The Spaniards recognized the superiority of the English fleet and returned home, defeated.

The Armada was _________________ on one side.

One way kidney stones can form is when urine produced in the kidneys is overly concentrated with calcium or oxalate. Reducing dietary calcium has been thought, therefore, to decrease the likelihood that

calcium will concentrate and form additional stones. Oddly enough, for many people the chances of recurrence are decreased by increasing calcium intake.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?

Exactly six piano classes are given sequentially on Monday: two with more than one student and four with exactly one student. Exactly four females -- Gimena, Holly, Iyanna, and Kate -- and five males -- Leung, Nate, Oscar, Pedro, and Saul -- attend these classes. Each student attends exactly one class. The following must obtain:

Iyanna and Leung together constitute one class.
Pedro and exactly two others together constitute one class.
Kate is the first female, but not the first student, to attend a class.
Gimena's class is at some time after Iyanna's but at some time before Pedro's.
Oscar's class is at some time after Gimena's.

If Oscar and Pedro do not attend the same class as each other, then which one of the following could be true?

Scientists have long known that the soft surface of the bill of the platypus is perforated with openings that contain sensitive nerve endings. Only recently, however, have biologists concluded on the basis of new evidence that the animal uses its bill to locate its prey while underwater, a conclusion suggested by the fact that the animal's eyes, ears, and nostrils are sealed when it is submerged. The new evidence comes from neurophysiological studies, which have recently revealed that within the pores on the bill there are two kinds of sensory receptors: mechanoreceptors, which are tiny pushrods that respond to tactile pressure, and electroreceptors, which respond to weak electrical fields. Having discovered that tactile stimulation of the pushrods sends nerve impulses to the brain, where they evoke an electric potential over an area of the neocortex much larger than the one stimulated by input from the limbs, eyes, and ears, Bohringer concluded that the bill must be the primary sensory organ for the platypus. Her finding was supported by studies showing that the bill is extraordinarily sensitive to tactile stimulation: stimulation with a fine glass stylus sent a signal by way of the fifth cranial nerve to the neocortex and from there to the motor cortex. Presumably nerve impulses from the motor cortex then induced a snapping movement of the bill. But Bohringer's investigations did not explain how the animal locates its prey at a distance.

Scheich's neurophysiological studies contribute to solving this mystery. His initial work showed that when a platypus feeds, it swims along, steadily wagging its bill from side to side until prey is encountered. It thereupon switches to searching behavior, characterized by erratic movements of the bill over a small area at the bottom of a body of water, which is followed by homing in on the object and seizing it. In order to determine how the animal senses prey and then distinguishes it from other objects on the bottom, Scheich hypothesized that a sensory system based on electroreception similar to that found in sharks might exist in the platypus. In further experiments he found he could trigger the switch from patrolling to searching behavior in the platypus by creating a dipole electric field in the water with the aid of a small 1.5-volt battery. The platypus, sensitive to the weak electric current that was created, rapidly oriented toward the battery at a distance of 10 centimeters and sometimes as much as 30 centimeters. Once the battery was detected, the platypus would inevitably attack it as if it were food. Scheich then discovered that the tail flicks of freshwater shrimp, a common prey of the platypus, also produce weak electric fields and elicit an identical response. Scheich and his colleagues believe that it is reasonable to assume that all the invertebrates on which the platypus feed must produce electric fields.

Which one of the following strategies is most similar to Scheich's experimental strategy as it is described in the passage?

The folktale that claims that a rattlesnake's age can be determined from the number of sections in its rattle is false, but only because the rattles are brittle and sometimes partially or completely break off. So if they were not so brittle, one could reliably determine a rattlesnake's age simply from the number of sections in its rattle, because one new section is. formed each time a rattlesnake molts.

Which one of the following is an assumption the argument requires in order for its conclusion to be properly drawn?

"Old woman," grumbled the burly white man who had just heard Sojourner Truth speak, "do you think your talk about slavery does any good? I don't care anymore for your talk than I do for the bite of a flea." The tall, imposing black woman turned her piercing eyes on him. "Perhaps not," she answered, "but I'll keep you scratching." The little incident of the 1840s sums up all that Sojourner Truth was: utterly dedicated to spreading her message, afraid of no one, forceful and witty in speech. Yet forty years earlier, who could have suspected that a spindly slave girl growing up in a damp cellar in upstate New York would become one of the most remarkable women in American history? Her name then was Isabella (many slaves had no last names), and by the time she was fourteen she had seen both parents die of cold and hunger. She herself had been sold several times. By 1827, when New York freed its slaves, she had married and borne five children. The first hint of Isabella's fighting spirit came soon after wards, when her youngest son was illegally seized and sold. She marched to the courthouse and badgered officials until her son was returned to her. In 1843, inspired by religion, she changed her name to Sojourner (meaning "one who stays briefly")
Truth, and, with only pennies in her purse, set out to preach against slavery. From New England to Minnesota she trekked, gaining a reputation for her plain but powerful and moving words. Incredibly, despite being black and female (only white males were expected to be public speakers), she drew thousands to town halls, tents, and churches to hear her powerful, deep-voiced pleas on equality for blacks-and for women. Often she had to face threatening hoodlums. Once she stood before armed bullies and sang a hymn to them. Awed by her courage and her commanding presence, they sheepishly retreated.

During the Civil War she cared for homeless ex-slaves in Washington. President Lincoln invited her to the White House to bestow praise on her. Later, she petitioned Congress to help former slaves get land in the West. Even in her old age, she forced the city of Washington to integrate its trolley cars so that black and white could ride together. Shortly before her death at eighty-six, she was asked what kept her going. "I think of the great things," replied Sojourner.

Sojourner Truth was raised in a damp cellar in

In the decade from the mid-1980s to the mid-1990s, large corporations were rocked by mergers, reengineering, and downsizing. These events significantly undermined employees' job security.
Surprisingly, however, employees' perception of their own job security hardly changed over that period.
Fifty-eight percent of employees surveyed in 1984 and 55 percent surveyed in 1994 stated that their own jobs were very secure.

Each of the following contributes to an explanation of the surprising survey results described above EXCEPT:

Telephone companies are promoting "voice mail" as an alternative to the answering machine. By recording messages from callers when a subscriber does not have access to his or her telephone, voice mail provides a service similar to that of an answering machine. The companies promoting this service argue that it will soon make answering machines obsolete, since it is much more convenient, more flexible, and less expensive than an answering machine.

Which one of the following, if true, most calls into question the argument made by the companies promoting voice mail?

Donna Haraway's Primate Visions is the most ambitious book on the history of science yet written from a feminist perspective, embracing not only the scientific construction of gender but also the interplay of race, class, and colonial and postcolonial culture with the "Western" construction of the very concept of nature itself. Primatology is a particularly apt vehicle for such themes because primates seem so much like ourselves that they provide ready material for scientists' conscious and unconscious projections of their beliefs about nature and culture.

Haraway's most radical departure is to challenge the traditional disjunction between the active knower (scientist/historian) and the passive object (nature/history). In Haraway's view, the desire to understand nature, whether in order to tame it or to preserve it as a place of wild innocence, is based on a troublingly masculinist and colonialist view of nature as an entity distinct from us and subject to our control. She argues that it is a view that is no longer politically, ecologically, or even scientifically viable. She proposes an approach that not only recognizes diverse human actors (scientists, government officials, laborers, science fiction writers) as contributing to our knowledge of nature, but that also recognizes the creatures usually subsumed under nature (such as primates) as active participants in creating that knowledge as well. Finally, she insists that the perspectives afforded by these different agents cannot be reduced to a single, coherent reality ?there are necessarily only multiple, interlinked, partial realities.

This iconoclastic view is reflected in Haraway's unorthodox writing style. Haraway does not weave the
many different elements of her work into one unified, overarching Story of Primatology; they remain distinct
voices that will not succumb to a master narrative. This fragmented approach to historiography is familiar enough in historiographical theorizing but has rarely been put into practice by historians of science. It presents a complex alternative to traditional history, whether strictly narrative or narrative with emphasis on a causal argument.

Haraway is equally innovative in the way she incorporates broad cultural issues into her analysis. Despite decades of rhetoric from historians of science about the need to unite issues deemed "internal" to science (scientific theory and practice) and those considered "external" to it (social issues, structures, and beliefs), that dichotomy has proven difficult to set aside. Haraway simply ignores it. The many readers in whom this separation is deeply ingrained may find her discussions of such popular sources as science fiction, movies, and television distracting, and her statements concerning such issues as nuclear war bewildering and digressive. To accept her approach one must shed a great many assumptions about what properly belongs to the study of science.

Which one of the following best exemplifies the type of "traditional history" mentioned at the end of 3rd paragraph

Most people who shop for groceries no more than three times a month buy prepared frozen dinners regularly. In Hallstown most people shop for groceries no more than three times a month. Therefore, in Hallstown most people buy prepared frozen dinners regularly.

Which one of the following arguments has a flawed pattern of reasoning most like the flawed reasoning in the argument above?

Charles A. Lindbergh is remembered as the first person to make a nonstop solo flight across the Atlantic, in 1927. This feat, when Lindbergh was only twenty-five years old, assured him a lifetime of fame and public attention. Charles Augustus Lindbergh was more interested in flying airplanes than he was in studying. He dropped out of the University of Wisconsin after two years to earn a living performing

daredevil airplane stunts at country fairs. Two years later, he joined the United States Army so that he could go to the Army Air Service flight-training school. After completing his training, he was hired to fly mail between St. Louis and Chicago. Then came the historic flight across the Atlantic. In 1919, a New York City hotel owner offered a prize of $25,000 to the first pilot to fly nonstop from New York to Paris. Nine St. Louis business leaders helped pay for the plane Lindbergh designed especially for the flight. Lindbergh tested the plane by flying it from San Diego to New York, with an overnight stop in St. Louis. The flight took only 20 hours and 21 minutes, a transcontinental record. Nine days later, on May 20, 1927, Lindbergh took off from Long Island, New York, at 7:52 A. M. He landed at Paris on May 21 at 10:21 P. M. He had flown more than 3,600 miles in less than thirty-four hours. His flight made news around the world. He was given awards and parades everywhere he went. He was presented with the U. S. Congressional Medal of Honor and the first Distinguished Flying Cross. For a long time, Lindbergh toured the world as a U. S. goodwill ambassador. He met his future wife, Anne Morrow, in Mexico, where her father was the United States ambassador.

During the 1930s, Charles and Anne Lindbergh worked for various airline companies, charting new commercial air routes. In 1931, for a major airline, they charted a new route from the east coast of the United States to the Orient. The shortest, most efficient route was a great curve across Canada, over Alaska, and down to China and Japan. Most pilots familiar with the Arctic did not believe that such a route was possible. The Lindberghs took on the task of proving that it was. They arranged for fuel and supplies to be set out along the route. On July 29, they took off from Long Island in a specially equipped small seaplane. They flew by day and each night landed on a lake or a river and camped. Near Nome, Alaska, they had their first serious emergency. Out of daylight and nearly out of fuel, they were forced down in a small ocean inlet. In the next morning's light, they discovered they had landed on barely three feet of water. On September 19, after two more emergency landings and numerous close calls, they landed in China with the maps for a safe airline passenger route.

Even while actively engaged as a pioneering flier, Lindbergh was also working as an engineer. In 1935, he and Dr. Alexis Carrel were given a patent for an artificial heart. During World War I in the 1940s, Lindbergh served as a civilian technical advisor in aviation. Although he was a civilian, he flew over fifty combat missions in the Pacific. In the 1950s, Lindbergh helped design the famous 747 jet airliner. In the late 1960s, he spoke widely on conservation issues. He died August 1974, having lived through aviation history from the time of the first powered flight to the first steps on the moon and having influenced a big part of that history himself.

What happened immediately after Lindbergh crossed the Atlantic?

According to the author of the passage, which one of the following statements is true of the historiographical method employed by Haraway in Primate Visions?

A running track with a hard surface makes for greater running speed than a soft one, at least under dry conditions, because even though step length is shorter on ' a hard surface, the time the runner's foot remains in contact with the running surface is less with a hard surface.

Jane works at a fashion design company, and is having problems getting dressed for work.
She refuses to wear any color combination that does not go well together as many of her clients may look
down upon this. She has two pairs of skirts, brown and blue; three blouses, white, sky blue, and gray; four
pairs of stockings, red, black, brown, and blue; and two pairs of shoes, black and brown. The blue skirt
cannot be worn with red or brown stockings. Gray does not go well with brown.
Black does not go well with brown.

If Jane wears black shoes she will not wear:

Editorial: The structure of the present school calendar was established to satisfy the requirements of early-twentieth-century agricultural life. In those days, farmers needed their children to have long breaks during which they could remain at home and help with the harvest. The contemporary school year is thus made up of periods of study interspersed with long breaks. But agricultural life no longer occupies most of our citizens, so we can now make changes that serve the interests of children. Therefore, long breaks should be removed from the school calendar.

Which one of the following is an assumption on which the editorial's argument depends?

Exactly six piano classes are given sequentially on Monday: two with more than one student and four with exactly one student. Exactly four females -- Gimena, Holly, Iyanna, and Kate -- and five males -- Leung, Nate, Oscar, Pedro, and Saul -- attend these classes. Each student attends exactly one class. The following must obtain:

Iyanna and Leung together constitute one class.
Pedro and exactly two others together constitute one class.
Kate is the first female, but not the first student, to attend a class.
Gimena's class is at some time after Iyanna's but at some time before Pedro's.

Oscar's class is at some time after Gimena's.

Suppose the condition that Oscar attends a class after Gimena is replaced with the condition that Oscar attends a class before Gimena and after Kate.
If all the other conditions remain the same, then which class must Holly attend?

Scientists have long known that the soft surface of the bill of the platypus is perforated with openings that contain sensitive nerve endings. Only recently, however, have biologists concluded on the basis of new evidence that the animal uses its bill to locate its prey while underwater, a conclusion suggested by the fact that the animal's eyes, ears, and nostrils are sealed when it is submerged. The new evidence comes from neurophysiological studies, which have recently revealed that within the pores on the bill there are two kinds of sensory receptors: mechanoreceptors, which are tiny pushrods that respond to tactile pressure, and electroreceptors, which respond to weak electrical fields. Having discovered that tactile stimulation of the pushrods sends nerve impulses to the brain, where they evoke an electric potential over an area of the neocortex much larger than the one stimulated by input from the limbs, eyes, and ears, Bohringer concluded that the bill must be the primary sensory organ for the platypus. Her finding was supported by studies showing that the bill is extraordinarily sensitive to tactile stimulation: stimulation with a fine glass stylus sent a signal by way of the fifth cranial nerve to the neocortex and from there to the motor cortex. Presumably nerve impulses from the motor cortex then induced a snapping movement of the bill. But Bohringer's investigations did not explain how the animal locates its prey at a distance.

Scheich's neurophysiological studies contribute to solving this mystery. His initial work showed that when a platypus feeds, it swims along, steadily wagging its bill from side to side until prey is encountered. It thereupon switches to searching behavior, characterized by erratic movements of the bill over a small area at the bottom of a body of water, which is followed by homing in on the object and seizing it. In order to determine how the animal senses prey and then distinguishes it from other objects on the bottom, Scheich hypothesized that a sensory system based on electroreception similar to that found in sharks might exist in the platypus. In further experiments he found he could trigger the switch from patrolling to searching behavior in the platypus by creating a dipole electric field in the water with the aid of a small 1.5-volt battery. The platypus, sensitive to the weak electric current that was created, rapidly oriented toward the battery at a distance of 10 centimeters and sometimes as much as 30 centimeters. Once the battery was detected, the platypus would inevitably attack it as if it were food. Scheich then discovered that the tail flicks of freshwater shrimp, a common prey of the platypus, also produce weak electric fields and elicit an identical response. Scheich and his colleagues believe that it is reasonable to assume that all the invertebrates on which the platypus feed must produce electric fields.

During the studies supporting Bohringer's finding, as they are described in the passage, which one of the following occurred before a nerve impulse reached the motor cortex of the platypus?

Every moral theory developed in the Western tradition purports to tell us what a good life is. However, most people would judge someone who perfectly embodied the ideals of any one of these theories not to be living a good life -- the kind of life they would want for themselves and their children.

The statements above, if true, most strongly support which one of the following?

Experts anticipate that global atmospheric concentrations of carbon dioxide (CO2) will have-doubled by the end of the twenty-first century. It is known that CO2 can contribute to global warming by trapping solar energy that is being reradiated as heat from the Earth's surface. However, some research has suggested that elevated CO2 levels could enhance the photosynthetic rates of plants, resulting in a lush world of agricultural abundance, and that this CO2 fertilization effect might eventually decrease the rate of global warming. The increased vegetation in such an environment could be counted on to draw more CO, from the atmosphere. The level of CO2 would thus increase at a lower rate than many experts have predicted.

However, while a number of recent studies confirm that plant growth would be generally enhanced in an atmosphere rich in CO2, they also suggest that increased CO2 would differentially increase the growth rate of different species of plants, which could eventually result in decreased agricultural yields. Certain important crops such as corn and sugarcane that currently have higher photosynthetic efficiencies than other plants may lose that edge in an atmosphere rich in CO2. Patterson and Flint have shown that these important crops may experience yield reductions because of the increased performance of certain weeds.
Such differences in growth rates between plant species could also alter ecosystem stability. Studies have shown that within rangeland regions, for example, a weedy grass grows much better with plentiful CO2 than do three other grasses. Because this weedy grass predisposes land to burning, its potential increase may lead to greater numbers of and more severe wildfires in future rangeland communities.

It is clear that the CO2 fertilization effect does not guarantee the lush world of agricultural abundance that once seemed likely, but what about the potential for the increased uptake of CO2 to decrease the rate of global warming? Some studies suggest that the changes accompanying global warming will not improve the ability of terrestrial ecosystems to absorb CO2. Billings' simulation of global warming conditions in wet tundra grasslands showed that the level of CO2 actually increased. Plant growth did increase under these conditions because of warmer temperatures and increased CO2 levels. But as the permafrost melted,
more peat {accumulated dead plant material) began to decompose. This process in turn liberated more
CO2 to the atmosphere. Billings estimated that if summer temperatures rose four degrees Celsius, the tundra would liberate 50 percent more CO2 than it does currently. In a warmer world, increased plant growth, which could absorb CO2 from the atmosphere, would not compensate for this rapid increase in decomposition rates. This observation is particularly important because high-latitude habitats such as the tundra are expected to experience the greatest temperature increase.

Which one of the following, if true, is LEAST consistent with the hypothesis mentioned in 2nd paragraph of the passage?

Many great inventions are greeted with ridicule and disbelief. The invention of the airplane was no exception. Although many people who heard about the first powered flight on December 17, 1903, were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation. Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brother's interest in flight grew into a compulsion. Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts. After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for them to design a machine that would fly. In 1903 the Wrights built their first airplane, which cost less than one thousand dollars. They even designed and built their own source of propulsion- a lightweight gasoline engine. When they started the engine on December 17, the airplane puffed wildly before taking off. The plane managed to stay aloft for twelve seconds, however, and it flew one hundred twenty feet. By 1905 the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons or in hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors of one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation.

People thought that the Wright brothers had ____.

There are exactly ten stores and no other buildings on Oak Street. On the north side of the street, from
west to east, are stores 1, 3, 5, 7, and 9; on the south side of the street, also from west to east, are stores
2, 4, 6, 8, and 10. The stores on the north side are located directly across the street from those on the

If all of the other conditions remain the same, then which one of the following statements must be true?

Political opinion and analysis outside the mainstream rarely are found on television talk shows, and it might be thought that this state of affairs is a product of the political agenda of the television stations themselves. In fact, television stations are driven by the same economic forces as sellers of more tangible goods. Because they must attempt to capture the largest possible share of the television audience for their shows, they air only those shows that will appeal to large numbers of people. As a result, political opinions and analyses aired on television talk shows are typically bland and innocuous.

An assumption made in the explanation offered by the author of the passage is that

Most scientists who study the physiological effects of alcoholic beverages have assumed that wine, like beer or distilled spirits, is a drink whose only active ingredient is alcohol. Because of this assumption, these scientists have rarely investigated the effects of wine as distinct from other forms of alcoholic beverages. Nevertheless, unlike other alcoholic beverages, wine has for centuries been thought to have healthful effects that these scientists ?who not only make no distinction among wine, beer, and distilled spirits but also study only the excessive or abusive intake of these beverages ?have obscured.

Recently, a small group of researchers has questioned this assumption and investigated the effects of moderate wine consumption. While alcohol has been shown conclusively to have negative physiological effects ?for example, alcohol strongly affects the body's processing of lipids (fats and other substances including cholesterol), causing dangerous increases in the levels of these substances in the blood, increases that are a large contributing factor in the development of premature heart disease ?the researchers found that absorption of alcohol into the bloodstream occurs much more slowly when subjects drink wine than when they drink distilled spirits. More remarkably, it was discovered that deaths due to

premature heart disease in the populations of several European countries decreased dramatically as the incidence of moderate wine consumption increased. One preliminary study linked this effect to red wine, but subsequent research has shown identical results whether the wine was white or red. What could
explain such apparently healthful effects?

For one thing, the studies show increased activity of a natural clot-breaking compound used by doctors to restore blood flow through blocked vessels in victims of heart disease. In addition, the studies of wine drinkers indicate increased levels of certain compounds that may help to prevent damage from high lipid levels. And although the link between lipid processing and premature heart disease is one of the most important discoveries in modern medicine, in the past 20 years' researchers have found several additional important contributing factors. We now know that endothelial cell reactivity (which affects the thickness of the innermost walls of blood vessels) and platelet adhesiveness (which influences the degree to which platelets cause blood to clot) are each linked to the development of premature heart disease. Studies show that wine appears to have ameliorating effects on both of these factors: it decreases the thickness of the innermost walls of blood vessels, and it reduces platelet adhesiveness. One study demonstrated a decrease in platelet adhesiveness among individuals who drank large amounts of grape juice. This finding may be the first step in confirming speculation that the potentially healthful effects of moderate wine intake may derive from the concentration of certain natural compounds found in grapes and not present in other alcoholic beverages.

The author suggests each of the following in the passage EXCEPT:

Exactly seven toy-truck models ?F, G, H, J, K, M, and S ?are assembled on seven assembly lines, exactly one model to a line. The seven lines are arranged side by side and numbered consecutively F through 7.
Assignment of models to lines must meet the following conditions:

F is assembled on a lower-numbered line than J.
M is assembled on the line numbered one lower than the line on which G is assembled.
H is assembled on line 1 or else line 7.
S is assembled on line 4.

If G is assembled on the line numbered one less than the line on which F is assembled, then which one of the following must be true?

Philosopher Denise Meyerson views the Critical Legal Studies (CLS) movement as seeking to debunk orthodox legal theory by exposing its contradictions. However, Meyerson argues that CLS proponents tend to see contradictions where none exist, and that CLS overrates the threat that conflict poses to orthodox legal theory.

According to Meyerson, CLS proponents hold that the existence of conflicting values in the law implies the absence of any uniquely right solution to legal cases. CLS argues that these conflicting values generate equally plausible but opposing answers to any given legal question, and, consequently, that the choice between the conflicting answers must necessarily be arbitrary or irrational. Meyerson denies that the existence of conflicting values makes a case irresolvable, and asserts that at least some such cases can be resolved by ranking the conflicting values. For example, a lawyer's obligation to preserve a client's confidences may entail harming other parties, thus violating moral principle. This conflict can be resolved if it can be shown that in certain cases the professional obligation overrides ordinary moral obligations.

In addition, says Meyerson, even when the two solutions are equally compelling, it does not follow that the choice between them must be irrational. On the contrary, a solution that is not rationally required need not be unreasonable. Meyerson concurs with another critic that instead of concentrating on the choice between two compelling alternatives, we should rather reflect on the difference between both of these answers on the one hand, and some utterly unreasonable answer on the other ?such as deciding a property dispute on the basis of which claimant is louder. The acknowledgment that conflicting values can
exist, then, does not have the far-reaching implications imputed by CLS; even if some answer to a problem
is not the only answer, opting for it can still be reasonable.

Last, Meyerson takes issue with the CLS charge that legal formalism, the belief that there is a quasi-deductive method capable of giving solutions to problems of legal choice, requires objectivism, the belief that the legal process has moral authority. Meyerson claims that showing the law to be unambiguous does not demonstrate its legitimacy: consider a game in which participants compete to steal the item of highest
value from a shop; while a person may easily identify the winner in terms of the rules, it does not follow
that the person endorses the rules of the game. A CLS scholar might object that legal cases are unlike games, in that one cannot merely apply the rules without appealing to, and therefore endorsing, external considerations of purpose, policy, and value. But Meyerson replies that such considerations may be viewed as part of, not separate from, the rules of the game.

The phrase "far-reaching implications" (line 36) refers to the idea that

Many political economists believe that the soundest indicator of the economic health of a nation is the nation's gross-national product (GNP) per capita ?a figure reached by dividing the total value of the goods produced yearly in a nation by its population and taken to be a measure of the welfare of the nation's
residents. But there are many factors affecting residents' welfare that are not captured by per capita GNP;
human indicators, while sometimes more difficult to calculate or document, provide sounder measures of a nation's progress than does the indicator championed by these economists. These human indicators
include nutrition and life expectancy; birth weight and level of infant mortality; ratio of population level to
availability of resources; employment opportunities; and the ability of governments to provide services
such as education, clean water, medicine, public transportation, and mass communication for their residents.

The economists defend their use of per capita GNP as the sole measure of a nation's economic health by claiming that improvements in per capita GNP eventually stimulate improvements in human indicators. But, in actuality, this often fails to occur. Even in nations where economic stimulation has brought about substantial improvements in per capita GNP, economic health as measured by human indicators does not always reach a level commensurate with the per capita GNP. Nations that have achieved a relatively high per capita GNP, for example, sometimes experience levels of infant survival, literacy, nutrition, and life expectancy no greater than levels in nations where per capita GNP is relatively low. In addition, because
per capita GNP is an averaged figure, it often presents a distorted picture of the wealth of a nation; for
example, in a relatively sparsely populated nation where a small percentage of residents receives most of the economic benefits of production while the majority receives very little benefit, per capita GNP may nevertheless be high. The welfare of a nation's residents is a matter not merely of total economic benefit, but also of the distribution of economic benefits across the entire society. Measuring a nation's economic health only by total wealth frequently obscures a lack of distribution of wealth across the society as a whole.

In light of the potential for such imbalances in distribution of economic benefits, some nations have begun to realize that their domestic economic efforts are better directed away from attempting to raise per capita GNP and instead toward ensuring that the conditions measured by human indicators are salutary. They recognize that unless a shift in focus away from using material wealth as the sole indicator of economic success is effected, the well-being of the nation may be endangered, and that nations that do well according to human indicators may thrive even if their per capita GNP remains stable or lags behind that of other nations

The passage provides specific information about each of the following EXCEPT:

Some government economists view their home countries as immune to outside influence. But economies
are always open systems; international trade significantly affects prices and wages. Just as physicists
learned the shortcomings of a mechanics based on idealizations such as the postulation of perfectly frictionless bodies, government economists must look beyond national borders if their nations' economies are to prosper.

The argument's conclusion follows logically if which one of the following is assumed?

In the sixteenth century, an age of great marine and terrestrial exploration, Ferdinand Magellan led the first expedition to sail around the world. As a young Portuguese noble, he served the king of Portugal, but he became involved in the quagmire of political intrigue at court and lost the king's favor. After he was dismissed from service to the king of Portugal, he offered to serve the future Emperor Charles V of Spain.
A papal decree of 1493 had assigned all land in the New World west of 50 degrees W longitude to Spain

and all the land east of that line to Portugal. Magellan offered to prove that the East Indies fell under Spanish authority. On September 20, 1519, Magellan set sail from Spain with five ships. More than a year later, one of these ships was exploring the topography of South America in search of a water route across the continent. This ship sank, but the remaining four ships searched along the southern peninsula of South America. Finally, they found the passage they sought near a latitude of 50 degrees S. Magellan named this passage the Strait of All Saints, but today we know it as the Strait of Magellan. One ship deserted while in this passage and returned to Spain, so fewer sailors were privileged to gaze at that first panorama of the Pacific Ocean. Those who remained crossed the meridian we now call the International Date Line in the early spring of 1521 after ninety-eight days on the Pacific Ocean. During those long days at sea, many of Magellan's men died of starvation and disease. Later Magellan became involved in an insular conflict in the Philippines and was killed in a tribal battle. Only one ship and seventeen sailors under the command of the Basque navigator Elcano survived to complete the westward journey to Spain and thus prove once and for all that the world is round, with no precipice at the edge.

The sixteenth century was an age of great ______________ exploration.

A test that examines people on their memory capacity for spatial layouts has placed Jason in the top 1 percentile of all test-takers. We can conclude from this that his memory capacity for things that do not involve spatial layouts will be below average.

Marie Curie was one of the most accomplished scientists in history. Together with her husband, Pierre, she discovered radium, an element widely used for treating cancer, and studied uranium and other radioactive substances. Pierre and Marie's amicable collaboration later helped to unlock the secrets of the atom. Marie was born in 1867 in Warsaw, Poland, where her father was a professor of physics. At the early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master's degree and doctorate in physics. Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress. Curie's feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world.

The Curies' ______________ collaboration helped to unlock the secrets of the atom.

North American eastern white cedars grow both on cliff faces and in forests. Cedars growing on exposed cliff faces receive very few nutrients, and rarely grow bigger than one-tenth the height of cedars growing in forests, where they benefit from moisture and good soil. Yet few eastern white cedars found in forests are as old as four hundred years, while many on cliff faces are more than five hundred years old.

Which one of the following, if true, most helps to explain the difference in the ages of the cedars on cliff faces and those in forests?

Donna Haraway's Primate Visions is the most ambitious book on the history of science yet written from a feminist perspective, embracing not only the scientific construction of gender but also the interplay of race, class, and colonial and postcolonial culture with the "Western" construction of the very concept of nature itself. Primatology is a particularly apt vehicle for such themes because primates seem so much like ourselves that they provide ready material for scientists' conscious and unconscious projections of their beliefs about nature and culture.

Haraway's most radical departure is to challenge the traditional disjunction between the active knower (scientist/historian) and the passive object (nature/history). In Haraway's view, the desire to understand nature, whether in order to tame it or to preserve it as a place of wild innocence, is based on a troublingly masculinist and colonialist view of nature as an entity distinct from us and subject to our control. She argues that it is a view that is no longer politically, ecologically, or even scientifically viable. She proposes an approach that not only recognizes diverse human actors (scientists, government officials, laborers, science fiction writers) as contributing to our knowledge of nature, but that also recognizes the creatures usually subsumed under nature (such as primates) as active participants in creating that knowledge as well. Finally, she insists that the perspectives afforded by these different agents cannot be reduced to a single, coherent reality ?there are necessarily only multiple, interlinked, partial realities.

This iconoclastic view is reflected in Haraway's unorthodox writing style. Haraway does not weave the
many different elements of her work into one unified, overarching Story of Primatology; they remain distinct
voices that will not succumb to a master narrative. This fragmented approach to historiography is familiar enough in historiographical theorizing but has rarely been put into practice by historians of science. It presents a complex alternative to traditional history, whether strictly narrative or narrative with emphasis on a causal argument.
Haraway is equally innovative in the way she incorporates broad cultural issues into her analysis. Despite

decades of rhetoric from historians of science about the need to unite issues deemed "internal" to science (scientific theory and practice) and those considered "external" to it (social issues, structures, and beliefs), that dichotomy has proven difficult to set aside. Haraway simply ignores it. The many readers in whom this separation is deeply ingrained may find her discussions of such popular sources as science fiction, movies, and television distracting, and her statements concerning such issues as nuclear war bewildering and digressive. To accept her approach one must shed a great many assumptions about what properly belongs to the study of science.

The passage suggests that Haraway would most probably agree with which one of the following statements about scientists observing animal behavior in the field?

President of the Regional Chamber of Commerce: We are all aware of the painful fact that almost no new businesses have moved into our region or started up here over the last ten years. But the Planning Board is obviously guilty of a gross exaggeration in its recent estimate that businesses are leaving the region at the rate of about four a week. After all, there were never more than about one thousand businesses in the region, so if they were really leaving at such a rate, they would all have been gone long ago.

In 1892 the Sierra Club was formed. In 1908 an area of coastal redwood trees north of San Francisco was established as Muir Woods National Monument. In the Sierra Nevada mountains, a walking trail from Yosemite Valley to Mount Whitney was dedicated in 1938. It is called John Muir Trail.
John Muir was born in 1838 in Scotland. His family name means "moor," which is a meadow full of flowers and animals. John loved nature from the time he was small. He also liked to climb rocky cliffs and walls.
When John was eleven, his family moved to the United States and settled in Wisconsin. John was good with tools and soon became an inventor. He first invented a model of a sawmill. Later he invented an alarm clock that would cause the sleeping person to be tipped out of bed when the timer sounded. Muir left home at an early age. He took a thousand-mile walk south to the Gulf of Mexico in 1867and 1868. Then he sailed for San Francisco. The city was too noisy and crowded for Muir, so he headed inland for the Sierra Nevadas.
When Muir discovered the Yosemite Valley in the Sierra Nevadas, it was as if he had come home. He loved the mountains, the wildlife, and the trees. He climbed the mountains and even climbed trees during thunderstorms in order to get closer to the wind. He put forth the theory in the late 1860's that the Yosemite Valley had been formed through the action of glaciers. People ridiculed him. Not until 1930 was Muir's theory proven correct. Muir began to write articles about the Yosemite Valley to tell readers about its beauty. His writing also warned people that Yosemite was in danger from timber mining and sheep ranching interests. In 1901 Theodore Roosevelt became president of the United States. He was interested in conservation. Muir took the president through Yosemite, and Roosevelt helped get legislation passed to create Yosemite National Park in 1906. Although Muir won many conservation battles, he lost a major one.
He fought to save the Hetch Valley, which people wanted to dam in order to provide water for San Francisco. In the late 1913 a bill was signed to dam the valley. Muir died in 1914. Some people say losing the fight to protect the valley killed Muir.

What happened first?

Conflict had existed between Spain and England since the 1570s. England wanted a share of the wealth that Spain had been taking from the lands it had claimed in the Americas. Elizabeth I, Queen of England, encouraged her staunch admiral of the navy, Sir Francis Drake, to raid Spanish ships and towns. Though these raids were on a small scale, Drake achieved dramatic success, adding gold and silver to England's treasury and diminishing Spain's omnipotence. Religious differences also caused conflict between the two countries. Whereas Spain was Roman Catholic, most of England had become Protestant. King Philip II of Spain wanted to claim the throne and make England a Catholic country again. To satisfy his ambition and also to retaliate against England's theft of his gold and silver, King Philip began to build his fleet of warships, the Armada, in January 1586. Philip intended his fleet to be indestructible. In addition to building new warships, he marshaled one hundred and thirty sailing vessels of all types and recruited more than nineteen thousand robust soldiers and eight thousand sailors. Although some of his ships lacked guns and others lacked ammunition, Philip was convinced that his Armada could withstand any battle with England.

The martial Armada set sail from Lisbon, Portugal, on May 9,1588, but bad weather forced it back to port.
The voyage resumed on July 22 after the weather became more stable. The Spanish fleet met the smaller, faster, and more maneuverable English ships in battle off the coast of Plymouth, England, first on July 31 and again on August 2. The two battles left Spain vulnerable, having lost several ships and with its ammunition depleted. On August 7, while the Armada lay at anchor on the French side of the Strait of Dover, England sent eight burning ships into the midst of the Spanish fleet to set it on fire. Blocked on one side, the Spanish ships could only drift away, their crews in panic and disorder. Before the Armada could regroup, the English attacked again on August 8. Although the Spaniards made a valiant effort to fight back, the fleet suffered extensive damage. During the eight hours of battle, the Armada drifted perilously close to the rocky coastline. At the moment when it seemed that the Spanish ships would be driven onto the English shore, the wind shifted, and the Armada drifted out into the North Sea. The Spaniards recognized the superiority of the English fleet and returned home, defeated.

The two battles left the Spanish fleet ________________.

The village of Vestmannaeyjar, in the far northern country of Iceland, is as bright and clean and up-to-date as any American or Canadian suburb. It is located on the island of Heimaey, just off the mainland. One January night in 1973, however, householders were shocked from their sleep. In some backyards red-hot liquid was spurting from the ground. Flaming "skyrockets" shot up and over the houses. The island's volcano, Helgafell, silent for seven thousand years, was violently erupting! Luckily, the island's fishing fleet was in port, and within twenty-four hours almost everyone was ferried to the mainland. But then the agony of the island began in earnest. As in a nightmare, fountains of burning lava spurted three hundred feet high. Black, baseball-size cinders rained down. An evil-smelling, eye-burning, throat-searing cloud of smoke and gas erupted into the air, and a river of lava flowed down the mountain. The constant shriek of escaping steam was punctuated by ear-splitting explosions. As time went on, the once pleasant village of Vestmannaeyjar took on a weird aspect. Its street lamps still burning against the long Arctic night, the town lay under a thick blanket of cinders. All that could be seen above the ten-foot black drifts were the tips of
street signs. Some houses had collapsed under the weight of cinders; others had burst into flames as the
heat ignited their oil storage tanks. Lighting the whole lurid scene, fire continued to shoot from the mouth of the looming volcano.

The eruption continued for six months. Scientists and reporters arrived from around the world to observe the awesome natural event. But the town did not die that easily. In July, when the eruption ceased, the people of Heimaey Island returned to assess the chances of rebuilding their homes and lives. They found tons of ash covering the ground. The Icelanders are a tough people, however, accustomed to the strange and violent nature of their Arctic land. They dug out their homes. They even used the cinders to build new roads and airport runways. Now the new homes of Heimaey are warmed from water pipes heated by molten lava.

The color of the hot liquid was

Zoos have served both as educational resources and as entertainment. Unfortunately, removing animals from their natural habitats to stock the earliest zoos reduced certain species' populations, endangering

their survival. Today most new zoo animals are obtained from captive breeding programs, and many zoos now maintain breeding stocks for continued propagation of various species. This makes possible efforts to reestablish endangered species in the wild.

Which one of the following statements is most strongly supported by the information above?

Always read the meter dials from the right to the left. This procedure is much easier, especially if any of the dial hands are near the zero mark. If the meter has two dials, and one is smaller than the other, it is not imperative to read the smaller dial since it only registers a small amount. Read the dial at the right first. As the dial turns clockwise, always record the figure the pointer has just passed. Read the next dial to the left and record the figure it has just passed. Continue recording the figures on the dials from right to left. When finished, mark off the number of units recorded. Dials on water and gas meters usually indicate the amount each dial records.

Always read the meter dials

The Galapagos Islands are in the Pacific Ocean, off the western coast of South America.
They are a rocky, lonely spot, but they are also one of the most unusual places in the world. One reason is that they are the home of some of the last giant tortoises left on earth. Weighing hundreds of pounds, these tortoises, or land turtles, wander slowly around the rocks and sand of the islands. Strangely, each of these islands has its own particular kinds of tortoises. There are seven different kinds of tortoises on the eight islands, each kind being slightly different from the other. Hundreds of years ago, thousands of tortoises wandered around these islands. However, all that changed when people started landing there.
When people first arrived in 1535, their ships had no refrigerators. This meant that fresh food was always a problem for the sailors on board. The giant tortoises provided a solution to this problem. Ships would anchor off the islands, and crews would row ashore and seize as many tortoises as they could. Once the animals were aboard the ship, the sailors would roll the tortoises onto their backs. The tortoises were completely helpless once on their backs, so they could only lie there until used for soups and stews.
Almost 100,000 tortoises were carried off in this way. The tortoises faced other problems, too. Soon after the first ships, settlers arrived bringing pigs, goats, donkeys, dogs and cats. All of these animals ruined life for the tortoises.

Donkey and goats ate all the plants that the tortoises usually fed on, while the pigs. Dogs and cats consumed thousands of baby tortoises each year. Within a few years, it was hard to find any tortoise eggs-or even any baby tortoises. By the early 1900s, people began to worry that the last of the tortoises would soon die out. No one, however, seemed to care enough to do anything about the problem. More and more tortoises disappeared, even though sailors no longer needed them for food. For another fifty years, this situation continued. Finally, in the 1950s, scientist decided that something must be done. The first part of their plan was to get rid of as many cats, dogs and other animals as they could. Next, they tried to make sure that more baby tortoises would be born. To do this, they started looking for wild tortoise eggs. They gathered the eggs and put them in safe containers. When the eggs hatched, the scientists raised the tortoises in special pens. Both the eggs and tortoises were numbered so that the scientists knew exactly which kinds of tortoises they had-and which island they came from. Once the tortoises were old enough and big enough to take care of themselves, the scientists took them back to their islands and set them loose. This slow, hard work continues today, and, thanks to it, the number of tortoises is now increasing every year. Perhaps these wonderful animals will not disappear after all.

What happens right after the tortoise eggs hatch?

The print circulation of The World Tribune has shown a 40 percent decline in the past two years. However, the traffic on the newspaper's website has increased by 30 percent during the same period. The website contains many news sections and blogs that are not featured in the print newspaper but are the most read pages of the website. Therefore, to maintain its profits, the newspaper has decided to discontinue its still-profitable print edition and to introduce more content on the website that is similar to the exclusive content on the most read pages of the website.

Which one of the following is an assumption on which the decision of The World Tribune depends?

For all species of higher animals, reproduction requires the production of eggs but not necessarily the
production of sperm. There are some species whose members are all female; the eggs produced by a rare
female-only species of salamander hatch without fertilization. This has the drawback that all offspring have genetic codes nearly identical to that of the single parent, making the species less adaptive than species containing both male and female members.

If the statements above are true, each of the following could be true EXCEPT:

There are exactly ten stores and no other buildings on Oak Street. On the north side of the street, from
west to east, are stores 1, 3, 5, 7, and 9; on the south side of the street, also from west to east, are stores
2, 4, 6, 8, and 10. The stores on the north side are located directly across the street from those on the
south side, facing each other in pairs, as follows: 1 and 2; 3 and 4; 5 and 6; 7 and 8; 9 and 10. Each store
is decorated with lights in exactly one of the following colors: green, red, and yellow. The stores have been decorated with lights according to the following conditions:

No store is decorated with lights of the same color as those of any store adjacent to it.
No store is decorated with lights of the same color as those of the store directly across the street from it.
Yellow lights decorate exactly one store on each side of the street.
Red lights decorate store 4.
Yellow lights decorate store 5.

If green lights decorate five stores on the street, then which one of the following statements must be true?

A nationwide poll of students, parents, and teachers showed that over 90 percent believe that an appropriate percentage of their school's budget is being spent on student counseling programs. It seems, then, that any significant increase in a school's budget should be spent on something other than student counseling programs.

Which one of the following describes a flaw in the reasoning of the argument above?

Because addictive drugs are physically harmful, their use by athletes is never justified. Purists, however, claim that taking massive doses of even such nonaddictive drugs as aspirin and vitamins before competing
should also be prohibited because they are unnatural. This is ridiculous; almost everything in sports is
unnatural, from high-tech running shoes to padded boxing gloves to highly-specialized bodybuilding machines. Yet, none of these is prohibited on the basis of its being unnatural. Furthermore, we should be attending to far more serious problems that plague modern sports and result in unnecessary deaths and injuries. Therefore, the use of nonaddictive drugs by athletes should not be prohibited.

Which one of the following can be inferred from the passage above?

One of the most intriguing stories of the Russian Revolution concerns the identity of Anastasia, the youngest daughter of Czar Nicholas II. During his reign over Russia, the Czar had planned to revoke many of the harsh laws established by previous czars. Some workers and peasants, however, clamored for more rapid social reform. In 1918 a group of these people, known as Bolsheviks, overthrew the government. On July 17 or 18, they murdered the Czar and what was thought to be his entire family. Although witnesses vouched that all the members of the Czar's family had been executed, there were rumors suggesting that Anastasia had survived. Over the years, a number of women claimed to be Grand Duchess Anastasia.
Perhaps the best nown claimant was Anastasia Tschaikovsky, who was also known as Anna Anderson.
In 1920, eighteen months after the Czar's execution, this terrified young woman was rescued from drowning in a Berlin river. She spent two years in a hospital, where she attempted to eclaim her health and shattered mind. The doctors and nurses thought that she resembled Anastasia and questioned her about her background. She disclaimed any connection with the Czar's family. Eight years later, though, she claimed that she was Anastasia. She said that she had been rescued by two Russian soldiers after the Czar and the rest of her family had been killed.
Two brothers named Tschaikovsky had carried her into Romania. She had married one of the brothers, who had taken her to Berlin and left her there, penniless and without a vocation. Unable to invoke the aid

of her mother's family in Germany, she had tried to drown herself. During the next few years, scores of the Czar's relatives, ex-servants, and acquaintances interviewed her. Many of these people said that her looks and mannerisms were evocative of the Anastasia that they had known. Her grandmother and other relatives denied that she was the real Anastasia, however. Tried of being accused of fraud, Anastasia immigrated to the United States in 1928 and took the name Anna Anderson. She still wished to prove that she was Anastasia, though, and returned to Germany in 1933 to bring suit against her mother's family.
There she declaimed to the court, asserting that she was indeed Anastasia and deserved her inheritance.
In 1957, the court decided that it could neither confirm nor deny Anastasia's identity. Although we will probably never know whether this woman was the Grand Duchess Anastasia, her search to establish her identity has been the subject of numerous books, plays, and movies.

Witnesses _____________ that all members of the Czar's family had been executed.

[1] Positive thinking sounds useful on the surface. [2] But "positive thinking" is also a soft and fluffy term that is easy to dismiss. [3] But those views may be changing. [4] Research is beginning to reveal that positive thinking is about much more than just being happy or displaying an upbeat attitude. [5] Positive thoughts can actually create real value in your life and help you build skills that last much longer than a smile. [6] The impact of positive thinking on your work, your health, and your life is being studied by researchers, one of whom is Barbara Fredrickson. [7] Fredrickson is a positive psychology researcher at the University of North Carolina, and she published a landmark paper that provides surprising insights about positive thinking and its impact on your skills. [8] Her work is among the most referenced and cited in her field, and it is surprisingly useful in everyday life.
(2)
[9] What do negative thoughts do to your brain? [10] Let's say that you're walking through the forest and suddenly a tiger steps onto the path ahead of you. [11] When this happens, your brain registers a negative emotion ?in this case, fear. [12] Researchers have long known that negative emotions program your brain to do a specific action. [13] When that tiger crosses your path, for example, you run. [14] The rest of the world doesn't matter. [15] You are focused entirely on the tiger, the fear it creates, and how you can get away from it. [16] In other words, negative emotions narrow your mind and focus your thoughts. [17] At that same moment, you might have the option to climb a tree, pick up a leaf, or grab a stick ?but your brain ignores all of those options because they seem irrelevant when a tiger is standing in front of you.
(3)
[18] This is a useful instinct if you're trying to save life and limb, but in our modern society, we don't have to worry about stumbling across tigers in the wilderness. [19] The problem is that your brain is still programmed to respond to negative emotions in the same way ?by shutting off the outside world and limiting the options, you see around you. [20] For example, when you're in a fight with someone, your anger and emotion might consume you to the point where you can't think about anything else. [21] Or, when you are stressed out about everything you have to get done today, you may find it hard to actually start anything because you're paralyzed by how long your to-do list has become. [22] In each case, your brain closes off from the outside world and focuses on the negative emotions of fear, anger, and stress ?

just like it did with the tiger. [23] Negative emotions prevent your brain from seeing the other options and choices that surround you. [24] It's your survival instinct.
(4)
[25] Now, let's compare this to what positive emotions do to your brain. [26] This is where Barbara Fredrickson returns to the story. [27] Fredrickson tested the impact of positive emotions on the brain by setting up a little experiment. [28] During this experiment, she divided her research subjects into five groups and showed each group different film clips. [29] The first two groups were shown clips that created positive emotions. [30] Group 1 saw images that created feelings of joy. [31] Group 2 saw images that created feelings of contentment. [32] Group 3 was the control group. [33] They saw images that were neutral and produced no significant emotion. [34] The last two groups were shown clips that created negative emotions. [35] Group 4 saw images that created feelings of fear. [36] Group 5 saw images that created feelings of anger. [37] Afterward, each participant was asked to imagine themselves in a situation where similar feelings would arise and to write down what they would do. [38] Each participant was handed a piece of paper with 20 blank lines that started with the phrase, "I would like to..." Participants who saw images of fear and anger wrote down the fewest responses. [39] Meanwhile, the participants who saw images of joy and contentment, wrote down a significantly higher number of actions that they would take, even when compared to the neutral group.
(5)
[40] In other words, when you are experiencing positive emotions like joy, contentment, and love, you will see more possibilities in your life. [41] These findings were among the first that suggested positive emotions broaden your sense of possibility and open your mind up to more options. [42] But that was just the beginning. [43] The benefits of positive emotions don't stop after a few minutes of good feelings subside. [44] In fact, the biggest benefit that positive emotions provide is an enhanced ability to build skills and develop resources for use later in life. [45] Let's consider a real-world example. [46] A child who runs around outside, swinging on branches and playing with friends, develops the ability to move athletically (physical skills), the ability to play with others and communicate with a team (social skills), and the ability to explore and examine the world around them (creative skills). [47] In this way, the positive emotions of play and joy prompt the child to build skills that are useful and valuable in everyday life. [48] These skills last much longer than the emotions that initiated them. [49] Years later, that foundation of athletic movement might develop into a scholarship as a college athlete or the communication skills may blossom into a job offer as a business manager. [50] The happiness that promoted the exploration and creation of new skills has long since ended, but the skills themselves live on. [51] Fredrickson refers to this as the "broaden and build" theory because positive emotions broaden your sense of possibilities and open your mind, which in turn allows you to build new skills and resources that can provide value in other areas of your life.
(6)
[52] All of this research begs the most important question of all: If positive thinking is so useful for developing valuable skills and appreciating the big picture of life, how do you actually get yourself to be positive? [53] Recent research by Fredrickson and her colleagues has revealed that people who meditate daily display more positive emotions that those who do not. [54] As expected, people who meditated also built valuable long-term skills. [55] For example, three months after the experiment was over, the people who meditated daily continued to display increased mindfulness, purpose in life, social support, and decreased illness symptoms.
(7)
[56] Secondly, a study published in the Journal of Research in Personality examined a group of 90 undergraduate students who were split into two groups. [57] The first group wrote about an intensely positive experience each day for three consecutive days. [58] The second group wrote about a control topic. [59] Three months later, the students who wrote about positive experiences had better mood levels, fewer visits to the health center, and experienced fewer illnesses.
(8)
[60] Positive thinking isn't just a soft and fluffy feel-good term. [61] Yes, it's great to simply "be happy," but those moments of happiness are also critical for opening your mind to explore and build the skills that become so valuable in other areas of your life. [62] Periods of positive emotion and unhindered exploration are when you see the possibilities for how your past experiences fit into your future life, when you begin to develop skills that blossom into useful talents later on, and when you spark the urge for further exploration and adventure.

Which one of the following would be an appropriate title to the passage?

If harriers are in the forest, then grosbeaks are not.
If jays, martins, or both are in the forest, then so are harriers
If wrens are in the forest, then so are grosbeaks
If jays are not in the forest, then shrikes are

While historians once propagated the myth that Africans who were brought to the New World as slaves contributed little of value but their labor, a recent study by Amelia Wallace Vernon helps to dispel this notion by showing that Africans introduced rice and the methods of cultivating it into what is now the United States in the early eighteenth century. She uncovered, for example, an 1876 document that details that in 1718 starving French settlers instructed the captain of a slave ship bound for Africa to trade for 400
Africans including some "who know how to cultivate rice." This discovery is especially compelling because the introduction of rice into what is now the United States had previously been attributed to French

Acadians, who did not arrive until the 1760s.

Vernon interviewed elderly African Americans who helped her discover the locations where until about 1920 their forebears had cultivated rice. At the heart of Vernon's research is the question of why, in an economy dedicated to maximizing cotton production, African Americans grew rice. She proposes two intriguing answers, depending on whether the time is before or after the end of slavery. During the period of slavery, plantation owners also ate rice and therefore tolerated or demanded its "after-hours" cultivation on patches of land not suited to cotton. In addition, growing the rice gave the slaves some relief from a system of regimented labor under a field supervisor, in that they were left alone to work independently.

After the abolition of slavery, however, rice cultivation is more difficult to explain: African Americans had acquired a preference for eating corn, there was no market for the small amounts of rice they produced, and under the tenant system ?in which farmers surrendered a portion of their crops to the owners of the land they farmed ?owners wanted only cotton as payment. The labor required to transform unused land to productive ground would thus seem completely out of proportion to the reward ?except that, according to Vernon, the transforming of the land itself was the point.

Vernon suggests that these African Americans did not transform the land as a means to an end, but rather as an end in itself. In other words, they did not transform the land in order to grow rice ?for the resulting rice was scarcely worth the effort required to clear the land ?but instead transformed the land because they viewed land as an extension of self and home and so wished to nurture it and make it their own. In addition to this cultural explanation, Vernon speculates that rice cultivation might also have been a political act, a next step after the emancipation of the slaves: the symbolic claiming of plantation land that the U.S. government had promised but failed to parcel off and deed to newly freed African Americans.

As described in the last paragraph of the passage, rice cultivation after slavery is most analogous to which one of the following?

Selena: Asteroid impact on the Earth caused the extinction of the dinosaurs by raising vast clouds of dust, thus blocking the Sun's rays and cooling the planet beyond the capacity of the dinosaurs, or perhaps the vegetation that supported them, to adapt. A worldwide dust layer provides evidence of asteroid impact at approximately the correct time, and a huge crater exists on the edge of the Yucatan peninsula in Mexico.
Trent: That asteroid crater is not large enough for the requisite amount of dust to have been produced.
Besides, the extinction of dinosaur species took many years, not just one or two.
So the extinctions must have been due not to asteroid impact on the Earth but to some other kind of cause.

Trent's argument assumes that

Lin: No, the companies would still have sufficient leverage in negotiations if they hired temporary replacements.

Which one of the following statements is most strongly supported by the exchange between David and Lin?

"Old woman," grumbled the burly white man who had just heard Sojourner Truth speak, "do you think your talk about slavery does any good? I don't care anymore for your talk than I do for the bite of a flea." The tall, imposing black woman turned her piercing eyes on him. "Perhaps not," she answered, "but I'll keep you scratching." The little incident of the 1840s sums up all that Sojourner Truth was: utterly dedicated to spreading her message, afraid of no one, forceful and witty in speech. Yet forty years earlier, who could have suspected that a spindly slave girl growing up in a damp cellar in upstate New York would become one of the most remarkable women in American history? Her name then was Isabella (many slaves had no last names), and by the time she was fourteen she had seen both parents die of cold and hunger. She

herself had been sold several times. By 1827, when New York freed its slaves, she had married and borne five children. The first hint of Isabella's fighting spirit came soon after wards, when her youngest son was illegally seized and sold. She marched to the courthouse and badgered officials until her son was returned to her. In 1843, inspired by religion, she changed her name to Sojourner (meaning "one who stays briefly")
Truth, and, with only pennies in her purse, set out to preach against slavery. From New England to Minnesota she trekked, gaining a reputation for her plain but powerful and moving words. Incredibly, despite being black and female (only white males were expected to be public speakers), she drew thousands to town halls, tents, and churches to hear her powerful, deep-voiced pleas on equality for blacks-and for women. Often she had to face threatening hoodlums. Once she stood before armed bullies and sang a hymn to them. Awed by her courage and her commanding presence, they sheepishly retreated.

During the Civil War she cared for homeless ex-slaves in Washington. President Lincoln invited her to the White House to bestow praise on her. Later, she petitioned Congress to help former slaves get land in the West. Even in her old age, she forced the city of Washington to integrate its trolley cars so that black and white could ride together. Shortly before her death at eighty-six, she was asked what kept her going. "I think of the great things," replied Sojourner.

She preached against

Studies of the reliability of eyewitness identifications show little correlation between the accuracy of a witness's account and the confidence the witness has in the account. Certain factors can increase or undermine a witness's confidence without altering the accuracy of the identification. Therefore, police officers are advised to disallow suspect lineups in which witnesses can hear one another identifying suspects.

Which one of the following is a principle underlying the advice given to police officers?

[17] At that same moment, you might have the option to climb a tree, pick up a leaf, or grab a stick ?but your brain ignores all of those options because they seem irrelevant when a tiger is standing in front of you.
(3)
[18] This is a useful instinct if you're trying to save life and limb, but in our modern society, we don't have to worry about stumbling across tigers in the wilderness. [19] The problem is that your brain is still programmed to respond to negative emotions in the same way ?by shutting off the outside world and limiting the options, you see around you. [20] For example, when you're in a fight with someone, your anger and emotion might consume you to the point where you can't think about anything else. [21] Or, when you are stressed out about everything you have to get done today, you may find it hard to actually start anything because you're paralyzed by how long your to-do list has become. [22] In each case, your brain closes off from the outside world and focuses on the negative emotions of fear, anger, and stress ? just like it did with the tiger. [23] Negative emotions prevent your brain from seeing the other options and choices that surround you. [24] It's your survival instinct.
(4)
[25] Now, let's compare this to what positive emotions do to your brain. [26] This is where Barbara Fredrickson returns to the story. [27] Fredrickson tested the impact of positive emotions on the brain by setting up a little experiment. [28] During this experiment, she divided her research subjects into five groups and showed each group different film clips. [29] The first two groups were shown clips that created

positive emotions. [30] Group 1 saw images that created feelings of joy. [31] Group 2 saw images that created feelings of contentment. [32] Group 3 was the control group. [33] They saw images that were neutral and produced no significant emotion. [34] The last two groups were shown clips that created negative emotions. [35] Group 4 saw images that created feelings of fear. [36] Group 5 saw images that created feelings of anger. [37] Afterward, each participant was asked to imagine themselves in a situation where similar feelings would arise and to write down what they would do. [38] Each participant was handed a piece of paper with 20 blank lines that started with the phrase, "I would like to..." Participants who saw images of fear and anger wrote down the fewest responses. [39] Meanwhile, the participants who saw images of joy and contentment, wrote down a significantly higher number of actions that they would take, even when compared to the neutral group.
(5)
[40] In other words, when you are experiencing positive emotions like joy, contentment, and love, you will see more possibilities in your life. [41] These findings were among the first that suggested positive emotions broaden your sense of possibility and open your mind up to more options. [42] But that was just the beginning. [43] The benefits of positive emotions don't stop after a few minutes of good feelings subside. [44] In fact, the biggest benefit that positive emotions provide is an enhanced ability to build skills and develop resources for use later in life. [45] Let's consider a real-world example. [46] A child who runs around outside, swinging on branches and playing with friends, develops the ability to move athletically (physical skills), the ability to play with others and communicate with a team (social skills), and the ability to explore and examine the world around them (creative skills). [47] In this way, the positive emotions of play and joy prompt the child to build skills that are useful and valuable in everyday life. [48] These skills last much longer than the emotions that initiated them. [49] Years later, that foundation of athletic movement might develop into a scholarship as a college athlete or the communication skills may blossom into a job offer as a business manager. [50] The happiness that promoted the exploration and creation of new skills has long since ended, but the skills themselves live on. [51] Fredrickson refers to this as the "broaden and build" theory because positive emotions broaden your sense of possibilities and open your mind, which in turn allows you to build new skills and resources that can provide value in other areas of your life.
(6)
[52] All of this research begs the most important question of all: If positive thinking is so useful for developing valuable skills and appreciating the big picture of life, how do you actually get yourself to be positive? [53] Recent research by Fredrickson and her colleagues has revealed that people who meditate daily display more positive emotions that those who do not. [54] As expected, people who meditated also built valuable long-term skills. [55] For example, three months after the experiment was over, the people who meditated daily continued to display increased mindfulness, purpose in life, social support, and decreased illness symptoms.
(7)
[56] Secondly, a study published in the Journal of Research in Personality examined a group of 90 undergraduate students who were split into two groups. [57] The first group wrote about an intensely positive experience each day for three consecutive days. [58] The second group wrote about a control topic. [59] Three months later, the students who wrote about positive experiences had better mood levels, fewer visits to the health center, and experienced fewer illnesses.
(8)
[60] Positive thinking isn't just a soft and fluffy feel-good term. [61] Yes, it's great to simply "be happy," but those moments of happiness are also critical for opening your mind to explore and build the skills that become so valuable in other areas of your life. [62] Periods of positive emotion and unhindered exploration are when you see the possibilities for how your past experiences fit into your future life, when you begin to develop skills that blossom into useful talents later on, and when you spark the urge for further exploration and adventure.

According to the passage, which one of the following is a tool that the author recommends to build positive thinking?

While historians once propagated the myth that Africans who were brought to the New World as slaves contributed little of value but their labor, a recent study by Amelia Wallace Vernon helps to dispel this notion by showing that Africans introduced rice and the methods of cultivating it into what is now the United States in the early eighteenth century. She uncovered, for example, an 1876 document that details that in 1718 starving French settlers instructed the captain of a slave ship bound for Africa to trade for 400
Africans including some "who know how to cultivate rice." This discovery is especially compelling because the introduction of rice into what is now the United States had previously been attributed to French Acadians, who did not arrive until the 1760s.

Vernon interviewed elderly African Americans who helped her discover the locations where until about 1920 their forebears had cultivated rice. At the heart of Vernon's research is the question of why, in an economy dedicated to maximizing cotton production, African Americans grew rice. She proposes two intriguing answers, depending on whether the time is before or after the end of slavery. During the period of slavery, plantation owners also ate rice and therefore tolerated or demanded its "after-hours" cultivation on patches of land not suited to cotton. In addition, growing the rice gave the slaves some relief from a system of regimented labor under a field supervisor, in that they were left alone to work independently.
After the abolition of slavery, however, rice cultivation is more difficult to explain: African Americans had acquired a preference for eating corn, there was no market for the small amounts of rice they produced, and under the tenant system ?in which farmers surrendered a portion of their crops to the owners of the land they farmed ?owners wanted only cotton as payment. The labor required to transform unused land to productive ground would thus seem completely out of proportion to the reward ?except that, according to Vernon, the transforming of the land itself was the point.

Vernon suggests that these African Americans did not transform the land as a means to an end, but rather as an end in itself. In other words, they did not transform the land in order to grow rice ?for the resulting rice was scarcely worth the effort required to clear the land ?but instead transformed the land because they viewed land as an extension of self and home and so wished to nurture it and make it their own. In addition to this cultural explanation, Vernon speculates that rice cultivation might also have been a political act, a next step after the emancipation of the slaves: the symbolic claiming of plantation land that the U.S. government had promised but failed to parcel off and deed to newly freed African Americans.

The main conclusion above follows logically if which one of the following is assumed?

Many great inventions are greeted with ridicule and disbelief. The invention of the airplane was no

exception. Although many people who heard about the first powered flight on December 17, 1903, were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation. Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brother's interest in flight grew into a compulsion. Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts. After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for them to design a machine that would fly. In 1903 the Wrights built their first airplane, which cost less than one thousand dollars. They even designed and built their own source of propulsion- a lightweight gasoline engine. When they started the engine on December 17, the airplane puffed wildly before taking off. The plane managed to stay aloft for twelve seconds, however, and it flew one hundred twenty feet. By 1905 the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons or in hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors of one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation.

The old tables were __________ and replaced by the first reliable figures for air pressure on curved surfaces.

Historian: The spread of literacy informs more people of injustices and, in the right circumstances, leads to increased capacity to distinguish true reformers from mere opportunists. However, widespread literacy
invariably emerges before any comprehensive system of general education; thus, in the interim, the
populace is vulnerable to clever demagogues calling for change. Consequently, some relatively benign regimes may ironically be toppled by their own "enlightened" move to increase literacy.

Which one of the following is an assumption on which the historian's argument depends?

The autobiographical narrative Incidents in the Life of a Slave Girl, Written by Herself (1861), by Harriet A.
Jacobs, a stave of African descent, not only recounts an individual life but also provides, implicitly and explicitly, a perspective on the larger United States culture from the viewpoint of one denied access to it.
Jacobs, as a woman and a slave, faced the stigmas to which those statuses were subject. Jacobs crafted her narrative, in accordance with the mainstream literary genre of the sentimental domestic novel, as an embodiment of cherished cultural values such as the desirability of marriage and the sanctity of personal identity, home, and family. She did so because she was writing to the free women of her day ?the principal readers of domestic novels ?in the hopes that they would sympathize with and come to understand her unique predicament as a female slave. By applying these conventions of the genre to her situation, Jacobs demonstrates to her readers that family and domesticity are no less prized by those forced into slavery, thus leading her free readers to perceive those values within a broader social context.

Some critics have argued that, by conforming to convention, Jacobs shortchanged her own experiences;
one critic, for example, claims that in Jacobs's work the purposes of the domestic novel overshadow those of the typical slave narrative. But the relationship between the two genres is more complex: Jacobs's attempt to frame her story as a domestic novel creates a tension between the usual portrayal of women in this genre and her actual experience, often calling into question the applicability of the hierarchy of values espoused by the domestic novel to those who are in her situation. Unlike the traditional romantic episodes in domestic novels in which a man and woman meet, fall in love, encounter various obstacles but eventually marry, Jacobs's protagonist must send her lover, a slave, away in order to protect him from the wrath of her jealous master. In addition, by the end of the narrative, Jacobs's protagonist achieves her freedom by escaping to the north, but she does not achieve the domestic novel's ideal of a stable home complete with family, as the price she has had to pay for her freedom is separation from most of her family, including one of her own children. Jacobs points out that, slave women view certain events and actions from a perspective different from that of free women, and that they must make difficult choices that free women need not. Her narrative thus becomes an antidomestic novel, for Jacobs accepts readily the goals of the genre, but demonstrates that its hierarchy of values does not apply when examined from the perspective of a female slave, suggesting thereby that her experience, and that of any female slave, cannot be fully understood without shedding conventional perspectives.

With which one of the following statements would the author of the passage be most likely to agree?

Four boys -- Fred, Juan, Marc, and Paul -- and three girls -- Nita, Rachel, and Trisha -- will be assigned to a row of five adjacent lockers, numbered consecutively 1 through 5, arranged along a straight wall. The following conditions govern the assignment of lockers to the seven children:

Each locker must be assigned to either one or two children, and each child must be assigned to exactly one locker.
Each shared locker must be assigned to one girl and one boy.
Juan must share a locker, but Rachel cannot share a locker.
Nita's locker cannot be adjacent to Trisha's locker. Fred must be assigned to locker 3

If lockers 1 and 2 are each assigned to one boy and are not shared lockers, then locker 4 must be assigned to

"Old woman," grumbled the burly white man who had just heard Sojourner Truth speak, "do you think your talk about slavery does any good? I don't care anymore for your talk than I do for the bite of a flea." The tall, imposing black woman turned her piercing eyes on him. "Perhaps not," she answered, "but I'll keep you scratching." The little incident of the 1840s sums up all that Sojourner Truth was: utterly dedicated to spreading her message, afraid of no one, forceful and witty in speech. Yet forty years earlier, who could have suspected that a spindly slave girl growing up in a damp cellar in upstate New York would become one of the most remarkable women in American history? Her name then was Isabella (many slaves had no last names), and by the time she was fourteen she had seen both parents die of cold and hunger. She herself had been sold several times. By 1827, when New York freed its slaves, she had married and borne five children. The first hint of Isabella's fighting spirit came soon after wards, when her youngest son was illegally seized and sold. She marched to the courthouse and badgered officials until her son was returned to her. In 1843, inspired by religion, she changed her name to Sojourner (meaning "one who stays briefly")
Truth, and, with only pennies in her purse, set out to preach against slavery. From New England to

Minnesota she trekked, gaining a reputation for her plain but powerful and moving words. Incredibly, despite being black and female (only white males were expected to be public speakers), she drew thousands to town halls, tents, and churches to hear her powerful, deep-voiced pleas on equality for blacks-and for women. Often she had to face threatening hoodlums. Once she stood before armed bullies and sang a hymn to them. Awed by her courage and her commanding presence, they sheepishly retreated.

During the Civil War she cared for homeless ex-slaves in Washington. President Lincoln invited her to the White House to bestow praise on her. Later, she petitioned Congress to help former slaves get land in the West. Even in her old age, she forced the city of Washington to integrate its trolley cars so that black and white could ride together. Shortly before her death at eighty-six, she was asked what kept her going. "I think of the great things," replied Sojourner.

The imposing black woman promised to keep the white man

A favorable biography of a politician omits certain incriminating facts about the politician that were available to anyone when the book was written. The book's author claims that, because he was unaware

of these facts when he wrote the book, he is not accountable for the fact that readers were misled by this omission. In a biographer, however, ignorance of this kind cannot be used to evade blame for misleading readers.

Which one of the following principles, if established, does most to justify the position advanced by the passage?

Scientists have long known that the soft surface of the bill of the platypus is perforated with openings that contain sensitive nerve endings. Only recently, however, have biologists concluded on the basis of new evidence that the animal uses its bill to locate its prey while underwater, a conclusion suggested by the fact that the animal's eyes, ears, and nostrils are sealed when it is submerged. The new evidence comes from neurophysiological studies, which have recently revealed that within the pores on the bill there are two kinds of sensory receptors: mechanoreceptors, which are tiny pushrods that respond to tactile pressure, and electroreceptors, which respond to weak electrical fields. Having discovered that tactile stimulation of the pushrods sends nerve impulses to the brain, where they evoke an electric potential over an area of the neocortex much larger than the one stimulated by input from the limbs, eyes, and ears, Bohringer concluded that the bill must be the primary sensory organ for the platypus. Her finding was supported by studies showing that the bill is extraordinarily sensitive to tactile stimulation: stimulation with a fine glass stylus sent a signal by way of the fifth cranial nerve to the neocortex and from there to the motor cortex. Presumably nerve impulses from the motor cortex then induced a snapping movement of the bill. But Bohringer's investigations did not explain how the animal locates its prey at a distance.

Scheich's neurophysiological studies contribute to solving this mystery. His initial work showed that when a platypus feeds, it swims along, steadily wagging its bill from side to side until prey is encountered. It thereupon switches to searching behavior, characterized by erratic movements of the bill over a small area at the bottom of a body of water, which is followed by homing in on the object and seizing it. In order to determine how the animal senses prey and then distinguishes it from other objects on the bottom, Scheich hypothesized that a sensory system based on electroreception similar to that found in sharks might exist in the platypus. In further experiments he found he could trigger the switch from patrolling to searching behavior in the platypus by creating a dipole electric field in the water with the aid of a small 1.5-volt battery. The platypus, sensitive to the weak electric current that was created, rapidly oriented toward the battery at a distance of 10 centimeters and sometimes as much as 30 centimeters. Once the battery was detected, the platypus would inevitably attack it as if it were food. Scheich then discovered that the tail flicks of freshwater shrimp, a common prey of the platypus, also produce weak electric fields and elicit an identical response. Scheich and his colleagues believe that it is reasonable to assume that all the invertebrates on which the platypus feed must produce electric fields.

It can be inferred from the passage that during patrolling behavior, the platypus is attempting to

Five racing drivers, Alan, Bob, Chris, Don, and Eugene, enter into a contest that consists of 6 races. The results of all six races are listed below: Bob always finishes ahead of Chris. Alan finishes either first or last.
Eugene finishes either first or last. There are no ties in any race.
Every driver finishes each race. In each race, two points are awarded for a fifth place finish, four points for fourth, six points for third, eight points for second, and ten points for first.

If Eugene finishes two places ahead of Chris in the first race, all of the following will be true EXCEPT:

Most people invest in the stock market without doing any research of their own. Some of these people rely solely on their broker's advice, whereas some others make decisions based merely on hunches. Other people do some research of their own, but just as often rely only on their broker or on hunches. Only a few always do their own research before investing. Nonetheless, a majority of investors in the stock market make a profit.

If the statements in the passage are true, which one of the following must also be true?

Forty years ago, hardly anybody thought about going to court to sue somebody. A person could bump a pedestrian with his Chrysler Airflow and the victim would say something like, "No harm done," and walk away. Ipso facto. No filing of codicils, taking of depositions or polling the jury. Attorneys need not apply.

Which one of the following sentences most logically continues the above passage?

The tendency toward overspecialization in the study of artifacts is unfortunate. Scholars can enhance their understanding of a certain artistic period by studying art from earlier periods that had a significant influence on it. For instance, because of its influence on Spanish artisans, a proper understanding of Arabic porcelain is indispensable for a proper understanding of Spanish porcelain.

Of the following, which one most closely conforms to the principle that the passage as a whole illustrates?

The rural community of Pottsville has a low crime rate. Urban Los Angeles has a high crime rate. Shady

Junction, a small agricultural community, has a high rate of criminal activity. The city of Washington, D.C. has a low rate of criminal activity.

Which one of the following most clearly expresses the main point in the passage above?

Which one of the following most accurately describes the organization of the final paragraph in the passage?
