Q40

From most people, the left half of brain controls linguistic capabilities, but some people

have their language centers in their 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 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 ever 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 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E，我B

损伤了左侧大脑，不一定就损伤了它的语言中枢，也可能是运动中枢。

所以从左侧大脑受伤而语言功能不受损并不能推出语言中枢一定在右侧大脑的结论。必须先假设左侧大脑损伤，一定导致语言中枢损伤。这即是D的表达。

现在ETS逻辑的正确答案有一种诈看像是无关项的趋势。发现很多题都是如此。
