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

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

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

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

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

我坚决选C，但是答案是E……哪位大师帮一下？？

不好意思，小葵MM，是我没有说清楚。我不是一定要你搜索，我是想请你按照标准格式修改一下标题，这样以后的人方便搜索。sorry。

另外，这个题目以前的确有过讨论的，我搜了一下，有6-7个链接。请你用“GWD－6－15”来搜索，注意中间的横杠必须是中文模式下的横杠。学会了搜索，可以节省你等待别人解答问题的时间：）

问题是：哪个选项能支持科学家的学说：Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.

相对于C，E有些牵强。

支持C。
