28-7: 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.

題目的推理是這樣的：老鼠因擁擠而更暴力，但一種猴子卻沒有因擁擠而多相互攻擊。因此可以推論出：所有的猴子都不會因擁擠而攻擊。

問加強

答案：這種猴子是所有猴子中最容易衝動的一種。即，如果這種猴子都不會因擁擠而相互攻擊，其它的猴子更沒有這種可能。
