7. GWD28-Q7:

In 1960’s studies of rats, scientists found that crowding increases the number of attacks among the animals significantly.But in recent experiments in which rhesus monkeys were placed in crowded conditions, although there was an increase in instances of “coping” behavior—such as submissive gestures and avoidance of dominant individuals—attacks did not become any more frequent.Therefore it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.

Which of the following, if true, most strengthens the argument?

A.All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.

B.In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.

C.Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.

D.Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.

E.Some of the coping behavior displayed by rhesus monkeys is similar to behavior rhesus monkeys use to bring to an end an attack that has begun.

答案C，我对E  C 都有疑问啊，能给这两个选项解释下吗

Easy. The author made a jump from one species of monkey to any species of monkey. It is a scope change which lacks support. C fixes that by saying the one species studied is the most easily provoked type.

E still talks about the one species. In that sense, E cannot fix the "any species of monkey" problem in the conlusion.

The author made a jump from one species of monkey to any species of monkey.
