Question

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.

Answer 1

e.-

Step-by-step explanation:

In a healthy person, normally the left side is the responsible to modulated and regulated the speaking, but the brain has the ability called plasticity, this is the result that some neurons or parts or the brain that were not used to regulate the speaking, when they are in a stress situation like this one, they tend to "learn" new skills, and this is how the patients can recover some of them speaking abilities after a stroke and with some therapies.
