Tony: Most web-pages on the internet have numerous enticing and hard-to-ignore hyperlinks, with each hyperlink leading to further hyperlinks and so on. Regularly falling into this bottomless hole of distracting and mostly trivial information on the internet decreases the ability of heavy internet users to do complex reasoning that requires focus and attention.
James: A research study has found that heavy internet users did better than infrequent users on tests for focus and attention and also had stronger muscles in the brain areas associated with complex reasoning, which suggests a higher usage of these muscles. The dialogue most strongly supports the claim that Tony and James disagree with each other about whether
A. focus and attention are necessary to do complex reasoningConservationist: The population of a certain wildflower is so small that the species is headed for extinction. However, this wildflower can cross-pollinate with a closely related domesticated daisy, producing viable seeds. Such cross-pollination could result in a significant population of wildflower-daisy hybrids. The daisy should therefore be introduced into the wildflower's range, since although the hybrid would differ markedly from the wildflower, hybridization is the only means of preventing total loss of the wildflower in its range.
Which one of the following is an assumption on which the conservationist's reasoning depends?
A. The wildflower currently reproduces only by forming seeds.As part of a survey, approximately 10,000 randomly selected individuals were telephoned and asked a number of questions about their income and savings. Those conducting the survey observed that the older the person being queried, the more likely it was that he or she would refuse to answer any of the questions. This finding clearly demonstrates that, in general, people are more willing when they are younger than when they are older to reveal personal financial information to strangers over the telephone.
The argument above is vulnerable to criticism on the grounds that the argument
A. offers no evidence that the individuals queried would have responded differently had they been asked the same questions in years prior to the surveyLecturer: There are many benefits to connecting everyday objects like cars and home appliances to the internet to enable their owners to manage them remotely. But beware of doing so! With the rising number and variety of devices connected to it, the internet is becoming more complex and, consequently, more prone to security breaches by hackers. The consequences of a security breach are much graver with an internet-connected car or home appliance than with an internet-connected computer and might even include a risk to the life of the owner of these objects.
Which one of the following most accurately expresses the main conclusion of the lecturer's argument?
A. The gravity of the consequences suffered by the owner of an internet-connected car or home appliance in the event of a security breach outweighs the benefits that these devices offer.Many of the presidents and prime ministers who have had the most successful foreign policies had no prior experience in foreign affairs when they assumed office. Although scholars and diplomats in the sacrosanct inner circle of international affairs would have us think otherwise, anyone with an acute political sense, a disciplined temperament, and a highly developed ability to absorb and retain information can quickly learn to conduct a successful foreign policy. In fact, prior experience alone will be of little value to a foreign policymaker who lacks all three of these traits.
If all of the statements above are true, which one of the following must be true?
A. Scholars and diplomats have more experience in foreign affairs than most presidents and prime ministers bring to office.Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth's ozone layer has been continuously depleted throughout the last 50 years. Atmospheric ozone blocks UV-B, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.
Each of the following, if true, would strengthen the argument EXCEPT:
A. Of the various types of radiation blocked by atmospheric ozone, UV-B is the only type that can damage genes.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?
A. It is clear that most drivers in West Island are safe drivers since there are very few driving accidents in West Island and most accidents there are not serious.Mr. Miko is very good at the sport of Judo. Therefore, Mr. Miko is a good sport.
The author of the argument above relies upon which one of the following to arrive at a conclusion?
A. purposely overestimating Mr. Miko's ability in Jodo.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.
When did the Lindberghs map an air route to China?
A. before they worked for an airlineThe okapi, a forest mammal of central Africa, has presented zoologists with a number of difficult questions since they first learned of its existence in 1900. The first was how to classify it. Because it was horse like in dimension, and bore patches of striped hide similar to a zebra's (a relative of the horse), zoologists first classified it as a member of the horse family. But further studies showed that, despite okapis' coloration and short necks, their closest relatives were giraffes. The okapi's rightful place within the giraffe family is confirmed by its skin-covered horns (in males), two-lobed canine teeth, and long prehensile tongue.
The next question was the size of the okapi population. Because okapis were infrequently captured by hunters, some zoologists believed that they were rare; however, others theorized that their habits simply kept them out of sight. It was not until 1985, when zoologists started tracking okapis by affixing collars equipped with radio transmitters to briefly captured specimens, that reliable information about okapi numbers and habits began to be collected. It turns out that while okapis are not as rare as some zoologists suspected, their population is concentrated in an extremely limited chain of forestland in northeastern central Africa, surrounded by savanna. One reason for their seeming scarcity is that their coloration allows okapis to camouflage themselves even at close range. Another is that okapis do not travel in groups or with other large forest mammals, and neither frequent open riverbanks nor forage at the borders of clearings, choosing instead to keep to the forest interior. This is because okapis, unlike any other animal in the central African forest, subsist entirely on leaves: more than one hundred species of plants have been identified as part of their diet, and about twenty of these are preferred. Okapis never eat one plant to the exclusion of others; even where preferred foliage is abundant, okapis will leave much of it uneaten, choosing to move on and sample other leaves, Because of this, and because of the distribution of their food, okapis engage in individual rather than congregated foraging.
But other questions about okapi behavior arise. Why, for example, do they prefer to remain within forested areas when many of their favorite plants are found in the open border between forest and savanna? One possibility is that this is a defense against predators; another is that the okapi was pushed into the forest by competition with other large, hoofed animals, such as the bushbuck and bongo, that specialize on the forest edges and graze them more efficiently, Another question is why okapis are absent from other nearby forest regions that would seem hospitable to them Zoologists theorize that okapis are relicts of an era when forestland was scarce and that they continue to respect those borders even though available forestland has long since expanded.
Based on the passage, in its eating behavior the okapi is most analogous to
A. a child who eats one kind of food at a time, consuming all of it before going on to the next kindNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
