120. 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 seenin 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.

答案选C

怎么就加强了呢？我怎么觉得有点削弱呢？

C是对的。因为结论是for any species of monkey, 所以答案里一定要把rhesus monkeys和any other monkeys联系起来。而且已经说了rhesus monkeys的attacks did not become any more frequent，所以当rhesus monkeys和any other monkeys一样，就可以下结论了。
