※ 引述《henry77ha (fsdae)》之铭言：
: 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.

属于外来资讯题目讨论对像为: 脑部受损之人，而非脑部未受损
之人。Assumption 基本上是不讨论不在 argument 讨论范围之
内的对象 (Support 则没有此限制)
答案（B）错误的真正原因说明如下：
