GWD-28-7<---ethyl更改标题（GWD 28-7 好像还没有标准答案，大家选啥？）

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.

我觉得C应该是正确选项。

OPEN TO DISGUSS

我选A，我觉得C无关；因为结论说的就是crowding会不会引起侵犯，没有讲猴子对其它刺激的反应。

结论是it is not likely that, for any species of monkey, crowding increases aggression as significantly as was seen in rats.

其中，any species 是个绝对化的概念，没有C，Rhesus monkeys 无法代表any species 。

所以，我认为只有C是正确的。

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

C的意思说R 猴子比其他猴子对aggression的刺激更敏感，所以R 也不吵架了，那就说明支持了结论，鼠比猴aggressive啊。请指教。

I chose C

偶选C，因为被选中的猴子比较具有代表性

同意楼上, 这是一个sample是否有代表性的题
