A study comparing a group of chronically depressed individuals with an otherwise matched group of individuals free from depression found significantly more disorders of the immune system among the depressed group. According to the researchers, these results strongly support the hypothesis that mental states influence the body's vulnerability to infection .

which of the following, if true, casts the most serious doubt on the researchers' interpretation of their findings ?

(c) Disorders of the immune system cause many of those individuals who have them to become chronically depressed.
(E) A high frequency of infections can stem from an unusually high level of exposure rather than from any disorder of the immune system.

Answer is C. 可我觉得E作为他因反对也可成立啊 ?

谢谢

The conclusion is "Mental states---> vulnerability of immune system". E show us that infections don't stem from disorder of the immune system, this is another story of disorder of the immune system, and has no any relationship with the argument.

E is so wrong. Let me give you a simper example: sleepiness --> loss of concentration; hunger--> loss of concentration; Either of these two is not the basis to dispute the other. In another word, we cannot say that because sleepiness causes loss of concentration, hunger must not cause loss of concentration. Unless there is a exclusivity clause in the argument, such that only one reason cause loss of concentration.

You misundertood E. If E said that the disorder of immune system in this group of people stems from higher level of exposure, it is the right answer.

谢谢两位。

但我不太同意MINDFREE的解释,他因削弱的方法是 从一个现象中不一定只能用A观点去解释,如果存在B观点也可以解释这一现象,那末我们无法说A一定成立,从而达到削弱的目的,而不一定要去证明A不对。

About braveMBA's explain, you want to say a high frequency of infections don't mean the body's vulnerablility to infection, don't you ? It seems a good explain.

welcome to discuss

我开始也选了E,但想了想,我认为主要错在 high frequency 上,文中并没有说严重程度,所以这个不能削弱

所以说,做逻辑题时,对关键词的把握和理解是非常重要的.

其实我做这题的时候,一看见A-->B,马上就想到反对的方式是它因或因果倒置,C显然就是因果倒置。E中的exposure不知为何物。
