问题     Was resource intensification—an increase in labor and time devoted to subsistence activities in order to increase food yields—by Dorset Paleo-Eskimos and Recent Indians on the island of Newfoundland simply a response to population pressure? Not exactly. On Newfoundland, population pressure did not result from a steadily growing resident population but, rather, from the arrival and lingering presence of new and significantly different populations. Newfoundland’s hunter-gatherer populations—both resident and newcomer—adjusted to the presence of other populations through niche differentiation. Building on a tradition that emphasized marine resources, Dorset Paleo-Eskimos intensified their harvest of seals in response to the arrival of Recent Indians in the first few centuries A.D. Recent Indians who were more familiar with broad-based, interior-maritime adaptation, intensified this strategy to cope with the Dorset. [br] Which of the following best describes the function of the highlighted sentence in the context of the passage as a whole?
选项 A、It points out a flaw in a theory discussed earlier in the passage.
B、It demonstrates the need for additional research on a phenomenon mentioned earlier in the passage.
C、It underscores the importance of a trait mentioned earlier in the passage.
D、It supports an assertion made earlier in the passage.
E、It questions the evidence for a tradition mentioned earlier in the passage
答案 D
解析 本题属于功能题，正确答案是定位句3s版本。本文第五六两句都是支持第三四句观点的例子，因此3s版本服从三四句，即“资源强化应对的是外来人口”，因此选项D正确。an assertion made earlier in the passage对应的便是三四句的观点。A、C、E项：既然定位句是例子，因此功能上只能用于支持观点，而非反驳观点。B项文中未提及。
