Q40:

For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half. When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way. Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.

Which of the following is an assumption on which the reasoning in the argument above depends?

No part of a person’s brain that is damaged by a stroke ever recovers.
Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain.
If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them.
It is impossible to determine which side of the brain contains a person’s language centers if the person has not suffered damage to either side of the brain.

全文说，人的语言中心多数在左脑，但也有人的语言中心在右脑。当一个语言中心被损坏，例如，因为中风，人的语言能力多多少少会受到损害。所以，如果一个人的左脑出现很严重的中风，语言能力没有收到破坏的话，那么这个人的语言中心一定在右脑。

问假设。原文只是说“当一个语言中心被损坏，例如，因为中风，人的语言能力多多少少会受到损害。”，原文并没有说中风一定会引起语言中心的损坏，这就是D的意思。D说，如果人的左脑有一些语言中心，任何严重影响到左脑的中风都会至少损坏其中一个语言中心（所以语言能力也会因此受影响）。只有assume了这个（中风一定会引起语言中心的损坏），才能得出原文"Therefore..."的结论。
