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?

S:摄入很多的蛋白质和脂肪肯定很健康，因为人类的祖先都是这样进化来的
J：人类的祖先运动量很大，但现在的人基本不怎么运动
问：J通过怎样的方式回答了S
A：反驳S的言论。J没有反驳
B：说一个事来建议S修正她的言论，显然正确
C：说一个事支持S的结论。J没有支持
D：质疑S关于人类祖先的观点能否得到人类进化的结论，显然离题远了
E：质疑现在的人是否和人类祖先一样健康，J只是陈述事实

整体来说，应该是部分ｗｅａｋｅｎ（承认食谱的作用，同时提出新的促进因素（高运动量）对于进化的意义） 部分ｗｅａｋｅｎ不算ｒｅｂｕｔｅ，可以视作找出不足建议修改

我在B和C中犹豫，现在知道了：C是suggests a way to broaden it，就是扩大范围；但是J这样说明显是限定条件范围，说你S的结论不是不对，而是人家ancestors之所以可以遵循这样diet保持健康，是因为人家有运动，也就是除了遵循这样的diet之外，还要加多一个条件去限定exerted themselves intensely，这样你的结论才是对的。

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.

亮闪闪的昵称呢
类比推理削弱结论找不同点---古代人现代人运动量不同，类比不成立

D也是Sasha 的逻辑错误，即史前人类大量吃肉 怎么就推出了 人类进化成了需要有肉才能繁荣，但是Jamal指出的并非这点；此外这个assumption指的是什么也不清楚

因为祖先吃大量的肉，所以人类进化成要吃肉才能繁荣昌盛；古代的人运动多，但是现在的人的运动少,因此应该把吃肉能让人类繁荣（健康）的结论限制在史前。

S：多吃肉有利于健康，因为古代的人吃很多的肉 J：古代的人运动多，但是现在的人的运动少 B选项说J提出了新信息，目的是建议S对他的结论进行限定（qualify），意思是S的结论要限定一些相同的条件，比如古代和现代的人的段落
