• Question 233:

  HOTSPOT

  Sales promotions can involve selling a product at a relatively low price or selling the product with a free (or seemingly free) unit of the product, as in "buy one, get one free" campaigns. Research shows that immediately following month-long sales promotions, a postpromotion dip may occur, i.e., sales for the following calendar month may be less than sales for the calendar month preceding the sales promotion. To increase sales, Storex, a department store, held month-long sales campaigns to promote four of its products. A sales promotion was considered successful if unit sales of the product were at least 10% higher in each of the 2 calendar months immediately following the promotion than In the month preceding it.

  Experts have offered explanations for postpromotion dip:

  I: Many consumers stockpile the product at relatively low cost during the sales promotion.

  II:";Buy one, get one fre"; promotions cause some consumers to undervalue the product, making them less likely to buy it following the sales promotion.

  HI: Many consumers who missed a";buy one, get one fre"; opportunity may, as a result, develop so-called inaction inertia, i.e., become less likely to buy the product at either the regular or even at a discount price than if the sales promotion had not occurred.

  HOTSPOT

  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.

  

  For each of the following regions, select Ye$\i the region's Species X population decreased from 1960 to 1975 AND the region's total mouse population exceeded 50 million In 1975. Otherwise, select No.

• Question 237:

  The author implies that if, in the experiment described in the second paragraph, the parasitic wasps had been drawn to the plants after they had been damaged by a razor blade but without application of oral secretions from the caterpillar, then scientists would likely have concluded which of the following?

  A. Wasps are attracted to the plants by the grassy odor released as the caterpillars feed on the plants' leaves.
  B. Wasps are attracted to the plants by volatile compounds released by the caterpillars as they digest the plant leaves that they consume.
  C. Wasps are attracted to the plants by volatile compounds released several hours after the caterpillars first begin consuming the plants' leaves.
  D. Wasps are attracted to the plants by volatile compounds released by the caterpillars rather than by odors created by the damage the caterpillars inflict on the plants' leaves.
  E. Wasps are more attracted to plants that have been infested by large numbers of caterpillars than to plants infested by relatively few caterpillars.
  A. Wasps are attracted to the plants by the grassy odor released as the caterpillars feed on the plants' leaves.

  Explanation/Reference:

  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 feeds 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 240:

  For each international call made to Country B last month, a certain telephone company charged a customer $075 to connect the cal plus a certain per-minute rate applied to each minute or part of a minute of the duration of the call. If the telephone company's total charge for the customer's calls to Country B last month was $84.00, what was the per- minute rate, in dollars?

  The telephone company connected 12 calls for the customer to Country B last month.

  (2)

  If the telephone company had no connection fee last month but had charged a per- minute rate that was 20 percent greater than the rate the customer was actually charged, then the total charge for the customer's calls to Country B last month would have been $90.00.
