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?
No part of a person's brain that is damaged by a stroke never 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
fact：①对大多数人来说，左边脑控制语言能力，一些人右边脑控制语言能力。②如果大脑的某一个语言中心被破坏，比如中风，语言能力就会受到损害。
因：左边脑受到严重的中风，但是语言能力没受影响
果：语言能力受右脑控制
gap：中风是不是一定会影响到大脑中控制语言能力的中心？？如果不影响的话也就无法知道 语言能力在哪边了
