Capuchin monkeys in Venezuela often rub a certain type of millipede into their fur. Secretions of these millipedes have been shown to contain two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate the capuchins. The rubbing behavior is rare except during the rainy season, when mosquito populations are at their peak. Therefore, the monkeys probably rub the millipedes into their fur because doing so helps protect them against mosquitoes.
Which of the following would it be most useful to determine in order to evaluate the argument?
Whether the two chemicals provide any protection for the millipedes against their own predators
Whether the type of millipede used by the capuchin monkeys in Venezuela is found in other parts of the world
Whether animals other than capuchins rub insects of any kind into their fur
Whether the only time the millipedes are readily available to the capuchins is during the rainy season
Whether secretions of any other insects accessible to the capuchins contain chemicals that repel mosquitoes
雷哥方向解题法（适用于有限时间无法看懂全部信息）：猴子怕蚊子，虫子可以驱蚊，雨季蚊子最多，所以猴子会在雨季抓虫子驱蚊，如何评价结论？A：虫子里面的化学物质为了抵御天敌（和方向完全无关）；B：虫子是不是在世界其他地方也有（和方向完全无关）；C：其它动物会不会抓虫子（和方向完全无关）；D：是不是雨季有这种虫子？（和方向相关，直接能决定是否这个假设发生在雨季）E：是不是任何虫子都能驱蚊（和方向相关，但扩大了范围，无法判断猴子是不是在雨季抓这种虫子，因为这种虫子也包含在所有虫子里面）。看到范围扩大词any，all很多选项可以秒删。
