monkeys

[frosty]

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.

Should be C.

if you negate C, that is "Rhesus monkeys do not respond with agression to a wider range of stimuli than any other monkeys do", then the conclusion falls apart because agressive behaviors could be expected to be observed when the same experimient is conducted on any other specie of monkey.

A. It weakens the argument saying that "coping" is not necessary due to crowding, and the comparison is referenced to a "crowding" experiment.
B. The main point is to evaluate the relation concluded by the author between monkeys and rats when placed on a certain condition, not just about the behavior of rats solely.
D. It weakens the conclusion saying that some monkeys reacted agressively in a distinguish manner.
E. It clearly weakens the conclusion, saying that agression existed before the coping behavior was observed.
