• Question 121:

  Scientists recently found traces of down on the fossil of a dinosaur, which they describe as typical of the kind that eventually, in birds, develops into feathers.

  A. recently found traces of down on the fossil of a dinosaur, which they describe as typical of the kind that eventually, in birds, develops

• Question 122:

  It is known from cave paintings and other evidence that the hunting people occupying the Bax Cave area in Country X tens of thousands of years ago repeatedly set fire to the surrounding area. Archaeologists hypothesize that because the fires caused later plant growth on the land, the hunters set the fires in order to attract herbivorous prey species. Such actions, they claim, are evidence for the mental capacity to delay gratification for weeks, months, or even years.

  Which of the following would it be most useful to determine in evaluating the archaeologists' claim?

  A. Whether the Bax Cave area is susceptible to fires caused by lightning strikes

  B. Whether remains can be found of hunting tools from tens of thousands of years ago in or near the Bax Cave

  C. Whether people occupying the Bax Cave tens of thousands of years ago consumed plants adapted to fire ecologies

  D. Whether in the immediate aftermath of fires in the Bax Cave area, animals sought by hunters came to seek prey driven out of dens or other shelters

  E. Whether the mental capacity to delay gratification for weeks, months, or even years was exhibited by contemporaries of the people occupying the Bax Cave tens of thousands of years ago

  Correct Answer: C

• Question 123:

  The passage suggests that one reason that the "conditions of captivity" (see bolded text) were significant was that

  A. food and water were readily available to all members of a group

  B. researchers were unable to observe animals from an unobtrusive distance

  C. climatic conditions seldom matched those of the animals' natural habitat

  D. animals were unable to distance themselves from each other physically

  E. animals lacked opportunities to interact with members of other species

  Correct Answer: D

  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.

  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
