In the last sentence of the passage, the author refers to “recent archaeological discoveries” (lines 36-37) most probably in order to A. refute White’s suggestion that neither Maritn nor Krech adequately account for Paleoindians’ contributions to the Pleistocene extinctions B. cast doubt on the possibility that a more definitive theory regarding the causes of the Pleistocene extinctions may be forthcoming
C. suggest that Martin’s, Krech’s, and White’s theories regarding the Pleistocene extinctions are all open to question D. call attention to the most controversial aspect of all the current theories regarding the Pleistocene extinctions E. provide support for White’s questioning of both Martin’s and Krech’s positions regarding the role of Paleoindians in the Pleistocene extinctions
White observes that Martin’s thesis depends on coinciding dates for the arrival of humans and the decline of large animal species, and Krech, though aware that the dates are controversial, does not challenge them; yet recent archaeological discoveries are providing evidencethat the date of human arrival was much earlier than 11,000 years ago.
在White 发表观点后,又来个yet, 而且貌似应该不是支持White的呀。。为啥选E呢。
NN指教啊。谢谢! |
