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.
