Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.

Which of the following, if true, provides the most support for the scientists' hypothesis?

正确答案: C

Q15:


Capuchin monkeys often rub their bodies with a certain type of millipede.  Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins.  Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.






Which of the following, if true, provides the most support for the scientists’ hypothesis?






  1. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it.

  2. The two chemicals that repel mosquitoes also repel several other varieties of insects.

  3. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak.

  4. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies.

  5. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.

我觉得没有一个答案正确,唉,大家帮我看看

C. It puts two phenomena together and somehow relates them. It is support answer.

这题我选C,虽然看了前面很多XDJM讨论E正确,心里还是不太情愿舍去C,现在有了总教头的支持,心里踏实了许多。

Fact:一种猴子经常用某种动物来摩擦身体。

Evidence:这些动物尸体的分泌物富含两种有效驱逐蚊子的化学物质;而蚊子带有使猴子致病的寄生虫。

Conclusion:科学家猜测猴子拿这些动物来摩擦使为了使它们自己远离蚊子。

找个答案支持科学家假设的,即猴子们这么做就是为了赶蚊子用的。ABE无关,D也无关,吃不吃这些动物跟科学家的推测没有关系。C说只有雨季的时候猴子们才那么干,而雨季时蚊子是最多的,从而support the hypothesis。
