  Explanation/Reference:

  United States Geological Survey scientists have found that a cooling in Pacific Ocean temperatures ed to increases in ecologically threatening phytoplankton blooms m San Francisco Bay, California. The declining temperatures took place off the coast of California between 1999 and 2004. The occurrence of these blooms is surprising because such blooms are normally associated with increases n the amount of nutrients, such as nitrogen and phosphorus, entering estuaries from such sources as wastewater treatment plants and agricultural fields. In this case, the bay's phytoplankton blooms occurred during a period of decreasing nutrient concentration and inputs. The scientists discovered the effects of the cold Pacific temperatures by using biological and water-quality data collected over twenty-five years. The colder temperatures caused changes in the types, abundance, and migration patterns of marine life into the San Francisco Bay from coastal ocean waters. For example, marine life, such as fish, shrimp, and crabs, migrated to the warmer waters thot are found in the bay. The migrations increased the numbers of predators such as bay shrimp and Dungeness crabs that eat filter feeders, such as clams. Clams can filter large quantities of phytoplankton from the bay's water, which can prevent phytopldnklon blooms. With the increase in predators, there wds d corresponding decrease In clam populations and an increase in phytoplarkton.

  A. The argument above depends on which of the following assumptions?

• Question 407:

  Berlandia's senate recently introduced two bills to address the problem of overburdened landfills: one would require that at least 40 percent by weight of the plastics sold in that country be biodegradable, the other that at least 80 percent by weight of plastics sold there be recycled into useful products. One legislator, however, has claimed that biodegradable plastics cannot be recycled into useful products, even if the biodegradables are mixed with other plastics.

  The legislator's claim, if true, most strongly supports which of the following?

  A. If both bills are passed, violations of at least one of the new laws will undoubtedly occur.
  B. If both bills are passed, the amount of nonbiodegradable plastics that reach Berlandia's landfills will soon increase over present levels.
  C. The cost of products made from recycled plastics will increase significantly unless neither bill Is passed.
  D. If a plastic product contains a significant amount of recycled material, that product will probably not contain biodegradable materials as well.
  E. Eventually, only plastics that are biodegradable will be sold in Berlandia, whether or not both bills are passed.
  A. If both bills are passed, violations of at least one of the new laws will undoubtedly occur.

• Question 408:

  Which of the following most accurately expresses the main point of the passage?

  B. Researchers have invented a process to cloak objects from microwaves through the use of a novel engineered material that bends microwaves at extreme angles.
  C. Both the occurrence of mirages on hot roads and the cloaking of microwaves through a newly invented process result from the bending of light at extreme angles.
  D. Microwaves and visible light both conform to a set of physical laws that explain mirages on hot roads.
  E. The movement of EMR around an object can be controlled by metal shapes like loops, coils, or tiny rectangles.
  A. Researchers inspired by observing mirages on hot roads have applied the underlying physical principles to develop a new process to cloak objects from microwaves.

  Explanation/Reference:

  Consider a mirage on a hot toad: when light rays hit the hot air just above the surface, they bend. Although light moves through a vacuum at a certain constant speed, it moves more slowly through any transparent medium, such as water or gas. Light travels faster in the thin air near the road than it does in the colder, denser air above, and the difference in speed makes it shift direction as it crosses the boundary between the two. Rays once headed downwards from the sky are redirected to your eye, hiding part of the road with a shimmering image. A research team has constructed an apparatus to cloak an object from electromagnetic radiation (EMR)--in this case, microwaves--making the object "invisible" to microwave- based detection devices, somewhat as a mirage on a hot road makes the road invisible. The apparatus bends incoming microwaves around the object, using a class of recently created metamaterials--materials that gain certain desired properties directly from their engineered structures rather than from their composition. These metamaterials possess the ability, not found in nature, to bend microwaves at extreme angles. The metamaterial in this case--thin, rigid sheets of fiberglass insulator stamped with conducting loops, coils, and tiny rectangles--was designed to control the movement of incoming EMR.

• Question 409:

  The decision as to when to bring charges for a criminal offense is the prerogative of the prosecutor, not the prospective defendant. This prerogative should not be put to unfair advantage. Sometimes decades elapse before charges are brought. Though this may be appropriate when striking new evidence implicates someone, bringing charges after many years simply because evidence favoring the prospective defendant has become inaccessible would be grossly unjust.

  Which of the following most accurately states the passage's main point?

  A. There should be safeguards to prevent criminal prosecutors from taking unfair advantage of the prerogative to decide when charges will be brought against a prospective defendant.
  B. Criminal prosecutors have an advantage over prospective defendants in that prosecutors get to decide when, if at all, charges will be brought.
  C. Criminal prosecutors should not take unfair advantage of their prerogative to decide when criminal charges will be brought against a prospective defendant.
  D. In some cases, it is unfair for a prosecutor, many years after an alleged offense has occurred, to bring charges against a prospective defendant for committing that offense.
  E. To bring charges against a prospective defendant after a delay of many years would be unjust.
  D. In some cases, it is unfair for a prosecutor, many years after an alleged offense has occurred, to bring charges against a prospective defendant for committing that offense.

• Question 410:

  Which of the following is a research shortcoming mentioned in the passage that is not addressed in the information provided about Sommer's study?

  A. lnadequate attention to the variability in postconflict behavior between groups of the same species
  B. Inadequate attention to the differences between various forms of postconflict behavior
  C. Inadequate attention to differences between species of colobine monkeys in postconflict behavior
  D. The restriction of most research to primates in captivity
  E. The study of primate groups in which only a small number of pairings took place
  A. lnadequate attention to the variability in postconflict behavior between groups of the same species

  ---

  Explanation/Reference:

  Members of many primate species approach an opponent shortly after conflict and initiate behaviors such as embracing, grooming, or huddling--a phenomenon researchers call postconflict reconciliation. Existing research, however, suffers from several shortcomings. The variability between groups of the same species is rarely addressed; the majority of studies investigate only a small fraction of the pairings that exist in a given group; and almost all reports are restricted to animals in captivity. In an attempt to address some of these shortcomings, Sommer et al. recently conducted a study of postconflict reconciliation in wild Hanuman langurs, a species of colobine monkey. They observed rates of postconflict reconciliation much lower than would be expected based on previous research, and found that over 80 percent of all pairings exhibited no postconflict affinity whatsoever. The rarity of friendly postconflict reunion in wild langurs draws attention to the possibility that conflicts are modulated through avoidance. The option of temporarily avoiding contact with opponents is not easily available to captive primates, and certainly not to the extent present in the wild. Still, studies of postconflict behavior of primates in captivity remain valuable: above all, they demonstrate the flexibility of nonhuman primates in various environments. It is likely, however, that the reported frequency of reconciliation among primates is artificially inflated by the conditions of captivity.
