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 damanged, for example by a stroke, linguistic capabilities are impaired in some way,. there fore, 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 ever recovers.
b impairment of liguistic 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 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.
Ans: D
咋是Ｄ呢？虽然Ｂ也不是很好，但是我看不出Ｄ哪里对了。if there are language centers on the left side of the brain，即使能说明左边脑，打击和损害的关系，我也看不出文章提到的右边脑的情况和这句话的关系啊。
