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
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。
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
qualify 有修订 限制的意思
相当于补充信息说什么条件下S的结论成立
相当于补充信息说什么条件下S的结论成立
