Critical Reasoning
试题详情
文章：
Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally, deer ticks pick up the bacterium while in the larval stage by feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. If the population of these other species were increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the bacterium would likely decline.
题目：
Which of the following would it be most important to ascertain in evaluating the argument?
选项:
A、Whether populations of the other species on which deer tick larvae feed are found only in areas also inhabited by white-footed miceWhether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on
B、Whether the infected deer tick population could be controlled by increasing the number of animals that prey on white-footed mice
C、Whether deer ticks that were not infected as larvae can become infected as adults by feeding on deer on which infected deer ticks have fed
D、Whether the other species on which deer tick larvae feed harbor any other bacteria that ticks transmit to humans
答案:
B
提问：
我的分析如下：
这里的因是：其他的物种数量增加
果是：感染细菌的的鹿虱的数量减少（这里没有提及是成年还是幼虫时期）
此时我承认他的因，但是切断因果之间的联系，提出还有另一种方法可以使鹿虱受感染，即：幼虫期未被感染的鹿虱是否会在成年期通过寄生在有染病鹿虱寄生的鹿身上而受到感染。使文章结论得到削弱，我不知道这个逻辑哪里有问题，还请指教~

提问：
老师可以梳理一下这个的逻辑链吗？ 一开始读懂了 但是在 “however certain other species on which the larvae feed do not harbor the bacterium"我理解的是 其他动物的 幼年吃这个 没有被感染，但后面又说的 if 那句话里面 more of the larvae would be feeding on uninfected hosts, so…… 这里的 这个 larvae 是指的 其他物种的 还是 deer 的？
