GWD28-Q7 麻烦高手帮忙

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.

答案是：C 

我认为是A

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. 这一段都是在讲rhesus monkeys

而最后一句结论就推到了for any species of monkey，是没根据的。所以C说rhesus monkeys 比其他monkeys更易激怒，这样rhesus monkeys 都没产生aggression行为才能推出任一猴子种类中拥挤不会引致aggression行为。

A的话说不拥挤的rhesus monkeys 种群中也有coping behavior，但没有提攻击行为，得不出任何结论。

是填补gap，谢谢o(∩_∩)o...

加强题找到线索进行加强就是了 这里要证明的是r这种猴子在所有猴群里是最具有代表性的，也就是要求他们最有攻击性
