后面忘记了
有个选项是关于以一种蜜蜂抗拒的化学物质做导引，我没怎么明白，选了这

GWD28-Q7:
In1960’s studies of rats, scientists found that crowding increases the number ofattacks among the animals significantly. But in recent experiments in which rhesus monkeys were placed in crowdedconditions, although there was an increase in instances of “coping”behavior—such as submissive gestures and avoidance of dominantindividuals—attacks did not become any more frequent.  Therefore it is not likely that, for anyspecies of monkey, crowding increases aggression as significantly as was seenin rats.
Whichof the following, if true, most strengthens the argument?
A.    Allthe observed forms of coping behavior can be found among rhesus monkeys livingin uncrowded conditions.
B.     Inthe studies of rats, nondominant individuals were found to increasingly avoiddominant individuals when the animals were in crowded conditions.
C.    Rhesusmonkeys respond with aggression to a wider range of stimuli than any othermonkeys do.
D.    Someindividual monkeys in the experiment were involved in significantly moreattacks than the other monkeys were.
E.     Someof the coping behavior displayed by rhesus monkeys is similar to behaviorrhesus monkeys use to bring to an end an attack that has begun.

62. 能源问题
   developing countries因为发展需要要大量使用oil 或者gases（具体是oil还是gas记不住），能源将会越开采越少，以后能源产量也会下降。虽然现在每年生产的oil 能够满足需要，但是现在能源大部分developed countries使用。economists 预测，在未来5年，即便能源保持从现在的产量，因为developing countries对oil 需求的大大上升，能源将会供不应求
问：economist的argument基于哪个假设。
选项：B developed countries对oil的需要正好等于oil的产量
      D 未来五年developed countries对oil的需求量将不会减少，其它选项记不清了，我选的D，不确定。
