问题 The author indicates explicitly that which of the following records has been a source of information in her investigation?
The primary purpose of the passage is to______
选项 A、support an alternative to an accepted methodology
B、present evidence that resolves a contradiction
C、introduce a recently discovered source of information
D、challenge a widely accepted explanation
E、argue that a discarded theory deserves new attention
答案D
解析 D is the best answer. The first paragraph describes a common assumption about the Great Migration, that the majority of migrants came from rural areas. It also restates the conclusion that is based on this assumption, that the subsequent economic difficulties of Black migrants in the North were a result of their unfamiliarity with urban life. In the second paragraph, the author states that the “question of who actually left the South” (lines 27-28) has never been adequately researched. She goes on to argue that Black migrants may actually have been from urban areas rather than rural areas, and thus that their subsequent economic problems in northern cities were not caused by their rural background. In making this argument, the author is challenging the “widely accepted explanation” presented in the first paragraph.
