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?



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

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

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

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

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

  Answer: E 错选C

正确答案应选C。

这个问题的论点是猴子抓某一种昆虫是因为可以帮助他们抵抗蚊子。

C，这个选项之所以加强结论是因为它表现了当原因出现的时候（蚊子多的时候），结果也出现了（猴子会抓身体）。

E，这个选项是说明两种分泌的物质对人类有致癌性，可是对猴子没有。这一点对结论并没有影响，因为它跟文章中提到的论点并没有关系。

E很明显是无关选项,连蚊子都没提到.

因為對猴子好，所以猴子才用

加強前提，對猴子好的為正確選項

要我說這裏基本上沒個特別好的

我個人翻譯是

一種猴子，經常往他們身上擦一些百足蟲。實驗證明，這種蟲子身上富含兩種能夠強力驅蚊的化學物質，還能使蚊子的什麼衰弱（反正就是說這個東西對猴子好）。科學家認為猴子往身上塗這些東西是為了不讓蚊子咬他們。

實在不好意思，C是錯誤選項
