9) The passage presents four developments that accompanied the decline of one Pueblo community: consumption of maize and domesticated turkeys fell, while that of wild plants and wild animals increased. This summary shows that answer Choices A and E are incorrect, since both refer to a drop in the consumption of wild plants. Since the passage says nothing about whether the consumption of wild plants affected nearby wildlife nor about whether it was a long-standing tradition, Choices B and D are incorrect. Choice C is correct, however: consumption of wild plants rose as that of maize and domesticated turkeys fell.
10) The research strongly suggests that when the Pueblo community was flourishing, maize and maize-fed turkey formed a substantial part of the inhabitants’ diet, but that just before the abandonment of Mesa Verde, maize had become a much scarcer commodity. This decline in what had been a dietary mainstay supports the claim that the villagers were experiencing difficulty growing crops. Thus Choice A is correct. Nothing in the passage suggests that the extent or date of the abandonment should be revised (Choices B and D), nor that the rate of the abandonment was affected by wild animals or varied from one community to another (Choices C and E).
