In 1960’s studies ofrats, scientists found that crowding increases the number of attacks among theanimals significantly. But in recentexperiments in which rhesus monkeys were placed in crowded conditions, althoughthere was an increase in instances of “coping” behavior—such as submissivegestures and avoidance of dominant individuals—attacks did not become any morefrequent. Therefore it is not likely that,for any species of monkey, crowding increases aggression as significantly aswas seen in rats. Which of the following,if true, most strengthens the argument?
All the observed forms of coping behavior can be found among rhesus monkeys living in uncrowded conditions.
In the studies of rats, nondominant individuals were found to increasingly avoid dominant individuals when the animals were in crowded conditions.
Rhesus monkeys respond with aggression to a wider range of stimuli than any other monkeys do.
Some individual monkeys in the experiment were involved in significantly more attacks than the other monkeys were.
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.
楼主,我一直琢磨你提出的这个问题,昨天还真心认为A对,但是今天我认为C对,因为it is not likely that,for any species of monkey, crowding increases aggression as significantly as was seen in rats. 这里面any species应该是说所有种类,由于前面是否定not,所以用any. 此题目的应该是考推理范围扩大后如何加强。除猕猴外所有猴子侵略性<猕猴侵略性<rats侵略性,所以加强结论。别再纠结了。上面有一哥们把英文解释也贴出来了,估计老外没咱们想这么多。
If you think that E might be the right answer, determine whether it neutralizes or counters a reasonable objection. Thus, the converse of E should clearly weaken the arguement. Whether or not the coping behaviour is similar to gestures used to end an attack seems irrelevant to the strength of the argument. If you disagree, explain how E could be relevant.
The most evident assumption made stems from the broadening of the scope of the evidence (rhesus monkeys) to the conclusion (all monkeys)

结论提出主干嘛,it is not likely that crowding increases aggression as significantly as was seen in rats.意思很明显啦,crowding是关键词,那么肯定就是说uncrowded的地方也有这些aggression,才能strengthen. C感觉是比较的category错误.
