• Question 281:

  In 1995 the United States National Park Service reintroduced wolves into Yellowstone National Park, from which they had been eliminated decades before by overhunting. Biologists hoped the reintroduction would return the park's mix of animals to a more natural state. After the wolves* disappearance, the population of their onetime prey, the elk. had burgeoned. Subsequently, new tree growth declined as multiplying elk browsed young trees, denuding certain areas of the park. Following the wolves" return, the elk population declined and young trees rebounded. Most scientists attribute the vegetation changes to the wolves" return. However. Patton observes that Yellowstone has not had a harsh winter since wolf numbers reached high levels and suggests that elk may not have needed to resort to trees for food.

  If the view attributed to the majority of scientists is correct, which of the following must be true?

  A. The elk population in Yellowstone had probably begun to decline prior to the reintroduction of wolves to the park.
  B. Browsing by species other than elk probably had a significant impact on young trees in Yellowstone.
  C. Human activity contributed both to the decline and to the resurgence of new tree growth in Yellowstone.
  D. The reintroduction of wolves to Yellowstone has had negative as well as positive effects on vegetation in the park.
  E. The rate at which young trees rebounded in Yellowstone following the reintroduction of wolves was in part due to weather patterns.
  C. Human activity contributed both to the decline and to the resurgence of new tree growth in Yellowstone.

• Question 284:

  A divide between aesthetic and technical considerations has played a crucial role in mapmakiug and cartographic scholarship. Some nineteenth-century cartographers, for instance, understood themselves as technicians who did not care about visual effects, while others saw themselves as landscape painters. That dichotomy structured the discipline of the history of cartography. Until the 1980s, in what Blakemore and Harley called "the 'Old is Beautiful' paradigm." scholars largely focused on maps made before 1800. marveling at their beauty and sometimes regretting the decline of the pre-technical age. Early mapmaking was considered art while modem cartography was located within the realm of engineering utility. Alpers. however, has argued that this boundary would have puzzled mapmakers in the seventeenth century, because they considered themselves to be visual engineers.

  It can be inferred from the passage that, beginning in the 1980s. historians of cartography

  A. placed greater emphasis on the beauty of maps made after 1800
  B. expanded their range of study to include more material created after 1800
  C. grew more sensitive to the way mapmakers prior to 1800 conceived of their work
  D. came to see the visual details of maps as aesthetic objects rather tlian practical cartographic aids
  E. reduced the attention they paid to the technical aspects of mapmaking
  B. expanded their range of study to include more material created after 1800
