关于楼上的问题,虽然年代久远但还是回答了它:

17行:Krech also contradicts Martin’s exclusion of climatic change as an explanation

可以作出选择

我的问题是,第7题如何排除C选项呢,我觉得B有很多不尽人意的地方

同问！BC好像都能削弱阿

c选项没有削弱结论

（C） Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras

krech反驳M理论的观点之一就是说M理论没有考虑气候因素

不同意

正是因为气候的大规模变化自始至终都存在，所以，可以推出气候的变化不会导致大规模的灭绝

5.   B, "Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene."
6.   E, "... does not challenge them ;  yet recent..."  the semicolon indicates the recent discovery is included in White's observation. It's here to support his question.
7.   B, "nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption."

"nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not
            all through human consumption."

not all说明Krech承认部分灭绝是由人导致的，所以选项B不能削弱Krech的结论。支持C
