### HideShow timer Statistics

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

I think C, but what does the rest of E say?

I say C as well.

E was also a good candidate, but it refers to "some" of the coping behavior.

It is clearly C.

There is a big jump in conclusion from RM to All monkeys.

For that to be true, C must be true.

Sounds more like a disguised assumption Q.

It must be C

experiments done on rhesus monkeys, they prove "coping"

==> conclusion for all the species of monkeys to be "coping"(less aggressive)

if rhesus monkeys are the most aggressive specie among all the species of monkeys, then it must strengthen the above argument as for other species it will be easier to cope, due to less aggressive nature.
