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?
7. 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. 在20世纪六十年代老鼠的研究,科学家发现拥挤能明显增加动物间打斗的数量。但是在最近的对于恒河猴的实验中发现,恒河猴被放置到拥挤的环境,尽管增加一些诸如顺从和避免支配的动作,打斗不是很经常的发生。因此对于猴的任何众位,拥挤增加的打斗都不可能和老鼠一样 Which of the following, if true, most strengthens the argument? P. All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions. Q. In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions. R. Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do. 恒河猴比其他猴子威胁的反应需要更广泛的刺激不明白什么意思,为什么是这两种的比较 S. Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were. T. 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. -----------------------------------------------
