Sasha: It must be healthy to follow a diet high in animal proteins and fats. Human beings undoubtedly evolved to thrive on such a diet, since our prehistoric ancestors ate large amounts of meat.
Jamal: But our ancestors also exerted themselves intensely in order to obtain this food, whereas most human beings today are much less physically active.
Jamal responds to Sasha by doing which of the following?
Refuting her statement about our prehistoric ancestors
Bringing forth a piece of information for the purpose of suggesting that she should qualify her main conclusion
Citing additional evidence that indirectly supports her conclusion and suggests a way to broaden it
Questioning whether her assumption about our prehistoric ancestors permits any conclusions about human evolution
Expressing doubts about whether most human beings today are as healthy as our prehistoric ancestors were
没能理解B里头的qualify her main conclusion的意思。
来自两本词典的解释：
1. If you qualify a statement, you make it less strong or less general by adding a detail or explanation to it.
2. moderate something: to make something less strong or extreme
所以这里qualify的意思是让Sasha不要把话说得那么绝对(Sasha说她的结论是undoubtedly)
Sasha: 高蛋白高脂肪的饮食对现代人有利，因为我们的祖先就吃大量的肉。
Jamal: 提出质疑，我们的祖先消耗比现在人要大。言下之意，现代人吃高蛋白高脂肪的饮食可能不大好，或者好是好，但是要少吃些，因为活动量没祖先大。
A 不是反驳的“prehistoric ancestors”
C 不是使得Sasha的观点变得宽泛
D 驳斥的不是人类进化的事
E 不是比较现代人和古人谁更健康
B 引入新的信息，表示Sasha不要太绝对。
Bringing forth a piece of information for the purpose of suggesting that she should qualify her main conclusion
提出一条信息，为了让她限制自己的主要结论
就是说她的结论太绝对了，应该考虑其他的限制因素
E看起来很对 但是健康的观点文中并没有提出 文中第一个人的结论说的是由于饮食关系 human evolve
qualify 有修订 限制的意思
J并没有完全的否定S的说法，只是提出了一个新的信息，希望S能完善她的说法。
Jamal并没有否定Sasha的结论。只是提出了一种情况Sasha的结论可能会不成立，所以jamal是希望Sasha更严谨的限定她的aargument。
不懂 限定条件是什么意思 祖先和现代人有区别 给出其他理由 祖先更爱运动所以吃肉导致繁荣了 加个条件现代人运动才能得出结论吃肉是健康的
qualify限定...
相当于补充信息说什么条件下S的结论成立
qualify限定...
相当于补充信息说什么条件下S的结论成立
错选d，把assumption想成evidence了。
B. Jamal's response indicates that our prehistoric ancestors were far more active than we are. This suggests not that Sasha is incorrect in her statement, but that her conclusion would benefit from this qualification: a diet high in animal protein and fat is healthy when one engages in intense physical activity at a level that is higher than what is normal for modern human beings. Jamal is providing new pieces of Information which Sasha is missing.
