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

xiahuistacy

我觉得也是选C

ringring

你這是哪一套的題

ringring

實在不好意思，C是錯誤選項

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。

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

E很明显是无关选项,连蚊子都没提到.
