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?

正确答案: D

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?

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 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.
答案为什么选D啊?at least one of them是至少大脑的一边吗?求中文解析。。。谢谢

one of them = one of language centers.

For necessary assumption question like this one, use negation method to find the right answer. If you negate D, you will have "If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain DOES NOT damage at least one of them", then the whole argument falles apart.  This means that D is required (necessary assumption) for the argument to hold.

For all NECESSARY  assumption questions, use the negation method.

这题A为什么不对啊,取非就是部分受到中风的损伤的大脑康复了,那不就削弱了原文结论因为无法分清是哪一边的语言中心受到了损伤么?
