9. When cut, the synthetic material fiberglass, like asbestos, releases microscopic fibers into the air. It is known that people who inhale asbestos, fibers suffer impairment of lung functions. A study of 300 factory workers who regularly cut fiberglass showed that their lung capacity is, on average, only 90 percent of that of a comparable group of people who do not cut fiberglass.

The statements above, if true, most strongly support which of the following hypotheses?
(A) People who work with fiberglass are likely also to work with asbestos.
(B) Fiberglass fibers impair lung function in people who inhale them.
(C) Fiberglass releases as many fibers into the air when cut as does asbestos.
(D) Coarse fibers do not impair lung function in people who inhale them.
(E) If uncut, fiberglass poses no health risk to people who work with it.
文章意思都明白，但当时选的是E，看正确答案感觉似懂非懂，求指教！

既然你文章意思看懂了，那我们直接来看选项：
A、C、D我们就不讨论了
下面看E：E说如果uncut，people就没事。但这并不能由文章所说“如果cut，那是由fiberglass release asbestos导致people的lung capacity变小”所证明。我们只知道cut的情况，uncut会怎样并不知道，不能简简单单由cut的后果推出uncut的后果
再看B：B说得就是文章想要论证的hypothese，一目了然


其实做这种逻辑题有时靠的是感觉，只要文章看懂了，再一瞄选项，突然就会觉得有个选项就是正确答案，那么这个就是正确答案，不要太纠结于一定要一个一个排除，考场上没有那么多时间给你一个个排除。当然，平时练习的时候还是需要研究每个错误的选项为什么错。
