exam pack2里面的新题,猜猜选哪个,说出你的思路?![](static/image/smiley/default/lol.gif)
•In 1960 studies of rat, 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, it was not such attacks that increased significantly,but rather instances of “coping” behavior, such as submissive gesture,avoidance of dominant individuals, and huddling with relatives. Therefore the evidence from rhesus monkeys makes it doubtful that crowding significantly increase aggressive impulses in primates.
•Which of the following, if true, most seriously weaken the argument?
•A The rhesus monkeyis the species of monkey that is most prone to fighting.
•B Coping behavior was adopted by the crowded monkeys to forestall acts of aggression among them.
•C All the observedforms of coping behavior can be found among rhesus monkeys living in uncrownedconditions.
•D Some individual monkeys in the experiments were involved in more attacks than the others.
•E Some of the rhesus monkeys in the experiments were subjected to levels of crowding that areunlikely to occur in natural circumstance.
官方答案是B
