• Question 141:

  Researchers studying long-term changes In regional mouse populations have found that by focusing on the populations of a rare but widespread and easily identifiable species of mouse (Species X), they can make fairly accurate estimations about the total regional mouse populations.

  In a report on a recent study that Included the data tables that follow, the researchers provided some addenda:

  1.

  "The Species X population of Region CV increased by 123,995 between 1990 and 2005.

  2.

  In contrast, the Species X population of Region EW declined by about 52% during that same time.

  

  The answer to which one of the following can be determined by using the information in the passage and tables?

  A. Between 1990 and 2005, did the Species X population of EW decrease by a greater number than the Species X population of CV increased?

  B. What was the approximate total mouse population of ]R in 2005?

  C. Did the Species X population of IQ increase between 1990 and 2005?

  D. Was the approximate total 2005 mouse population of TY larger or smaller than that of EW?

  E. What caused the Species X population of TY to increase so dramatically between 1975 and 1990?

• Question 148:

  It can be inferred from the passage that if the leaves of a plant were damaged by wind rather than by caterpillars, the parasitic wasps would

  A. not be significantly more attracted to the damaged plant than to other, undamaged plants

  B. not be attracted to the plant until several hours after the damage occurred

  C. be attracted to the plant if it gave off a grassy odor

  D. be attracted to the plant if other plants in its immediate vicinity had also been damaged by the wind

  E. be attracted to the plant even if the damage to the leaves was very minor

  Correct Answer: A

  Parasitic wasps propagate by injecting their eggs into a caterpillar that then becomes paralyzed as the eggs inside develop into wasp larvae. The wasp larvae kill the caterpillar host as they feed on it, form cocoons, and finally develop into wasps. In attempting to discover how such wasps detect the presence of the caterpillar hosts that are so critical to the wasps' propagation, researchers have uncovered an intriguing defense mechanism developed by the plants on which the caterpillars feed. When chewed on, many plants release volatile compounds from both damaged and undamaged tissues. When these compounds are toxic to the insects that feed on the plants, they can help defend the plants from such attacks. However, the plants on which the wasps' caterpillar hosts feed have evolved an even more complex defense: the caterpillar-infested plants appear to release volatile chemicals that attract parasitic wasps, which then prey on the caterpillars. Scientists originally suspected that the wasps were attracted by an odor, reminiscent of cut grass, that is released as the caterpillar feeds, but a recent study suggests that a different set of volatile attractants is involved. In this study, when researchers used a razor blade to mimic caterpillar damage on the leaves, only grassy odors were emitted, not the volatile compounds that attracted wasps. However, when oral secretions from the caterpillars were applied to these damaged leaves, the leaves released the wasp attractants several hours later. Further tests revealed that oral secretions placed on the razor-damaged leaves stimulated the release of such attractants, making the plants as attractive to wasps as plants that had suffered actual caterpillar damage. These results suggest that chemicals from the caterpillar must be present for these attractants to be released and that unlike the grassy scent, which emanates only as the caterpillar on the plant, the wasp attractants are produced several hours after the attack and persist for several hours, perhaps days. Researchers have launched additional studies to determine whether the wasps' capacity to prey on caterpillars can be enhanced to the extent that the wasps could be used as a natural pesticide to "police" plants and protect them from crop- destroying caterpillars.

• Question 150:

  Sorenson and Audia would most likely agree with which of the following statements about the intrinsic advantages mentioned in the highlighted text?

  A. Geographic concentration of production is, in many cases, maintained I* the economic benefits provided by these advantages.

  B. The expectation that these advantages should lead to lower failure rates is supported by organizational ecology studies.

  C. These advantages are insufficient as an explanation for geographic concentration of production.

  D. These advantages are often related not to a particular location but to the colocation of structurally equivalent organizations Itself.

  E. The benefits of these advantages are outweighed by intense competition from organizations outside local population boundaries.

  Correct Answer: C

  Organizations that produce similar goods tend to concentrate in the same geographic area (geographic concentration of production). Economic explanations of such industrial agglomeration explicitly emphasize better performance, and implicitly emphasize lower failure rates, as the key processes contributing to this geographic concentration. Sometimes Industries benefit economically from situating themselves in particular locations that offer intrinsic advantages such as access to scarce raw materials or proximity to consumers. In other cases, regardless of the particular location, the colocation of structurally equivalent organizations--those that operate in the same markets--may itself yield advantages such as common labor markets and knowledge spillovers. Sorenson and Audia point out that these explanations Ignore the fact that structurally equivalent organizations also compete with one another for vital resources, and colocation would be expected to increase such competition. Organizational ecology studies support this expectation by showing that organizations apparently compete more intensely within local population boundaries. Sorenson and Audia propose instead that what maintains geographic concentration is entrepreneurial opportunity, which leads to higher founding rates. Dense local concentrations of structurally equivalent organizations increase the pool of potential entrepreneurs in a region. Beginning entrepreneurs need exposure to existing organizations in the industry to acquire knowledge of the business, ties to scarce resources, and self-confidence. The existing geographic concentration of production constrains access to these resources, so that new founding's tend to reinforce geographic concentration.
