我也选了C
这么想的：K反对M之处在于K认为1：天气是一个影响因素,因为climatic change did indeed occur at the end of the Pleistocene. 。2：hunting至少不是首要原因，因为“large animal species vanished even in areas where there is no evidence to demonstrate that Paleoindians hunted them”
c说climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras，是一个有因无果的削弱（在承认原文开头所说的extinction发生在the end of the Pleistocene era 的前提下）
B说的Nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption。没看懂意思，请问这句话是谁的立场？我觉得是K的。
请大家帮我看看我的错在哪里，B对在哪里？
谢谢！ |
