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?
All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.
In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.
Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.
Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.
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.
1、实验数据：在rhesus monkey中增加crowding，attack和agression未显著提高
2、需要验证的结论：对于所有物种的猴子，加入crowding都不会增加attack和agression
A.coping behavior行为增加与agression无关
B.讲的是rats，没谈及到monkey，而且也没涉及到agression
C.证明了rhesus monkey这个物种在crowding情况下的反应，已经涵括了一切猴子物种（包含关系）
D.选项干扰了要证明结论的准确性
E.同D
