9. 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 seri-
ous doubt on the researchers' interpretation of their
findings?
(A) The researchers' view does little more than echo
a familiar theme in folklore an literature.
(B) Chronically depressed individuals are no less
careful than others to avoid exposure to
infections.
(C) Disorders of the immune system cause many of
those individuals who have them to become
chronically depressed.
(D) Individuals who have previously been free from
depression can become depressed quite
suddenly.
(E) A high frequency of infections can stem from
an unusually high level of exposure rather
than from any disorder of the immune system.
为什么E不对呢？这个题，有什么通用的思维模式吗？谢谢大家

E? Did the question ever mention "a high frequency of infections"?

Even though it is possible that new term might appear in the answer, there should be links btween the new term and the question. There is none in this question. And the question is about the relationship between disorder and depression. So even if there is a relationship between a high frequency of infections and disorder, it is out of the loop.

You can change the question a bit to make E a possible right answer. Think about it.
