T-9-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 brains 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?
A.
No part of a person’s brain that is damaged by a stroke never recovers
B.
Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
C.
Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain.
D.
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.
E.
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.
答案选D
但我实在不明白D的选项，请帮解释下~~~ 谢谢啦！！

题目：大部分人的左半脑控制语言能力，但有的人是右半脑控制。当中风的时候，大脑的语言中心受损，语言能力会在某程度被伤害。
因此，那些左脑遭受过中风的人如果没有受到什么（语言上的）伤害，那么他们的语言中心一定是在右半脑。
问前提。
A。有没恢复与题目无关
B。语言能力在那些没有受伤的人那里不会发生损害。继续无关
C。中风比其他伤害更能够损害语言能力。中风只不过是个例子
D。如果语言中枢在左脑，任何影响半脑的中风都会伤害至少其中一个半脑。（如果该病人语言能力没影响，则语言能力在右脑，否则在左）
回应原文最后一句的推断
E。必须受伤了才能鉴定位于哪个半脑。无关

这个题从原文中可以推断出来的，
就是stroke一定会损坏语言能力的，如果不损坏语言能力的话，则无法得出结论
