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 from feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline.
Which of the following, if true, most strengthens the argument?

分析B选项

L是一种通过鹿虱子传播给人的一种疾病，一般来看，鹿虱子在幼虫阶段吃了感染的白鼠，但是吃其他物种的老鼠就不会感染，如果别的物种增多，那么他们将增加吃未感染的物种的机会，所以感染病菌的概率就会降低
A: 虱子携带病毒不会有任何副作用，无关选项
B:还没有人类接触白鼠感染疾病的的例子，无关选项
C: 鹿虱子只在幼虫时期吃东西，原文是虱子在幼虫阶段吃了白鼠和吃其他物种的老鼠做比较，如果非幼虫阶段也吃东西，那么后期吃东西可能吃老鼠也会感染
D: 跳出讨论范围
E: 鹿虱子吃的其他物种不会携带其他传染给人类的细菌，其他细菌，跳出讨论范围

【因果推理】 前提：ticks所食用的其他物种增加 结论：携带细菌的ticks数量就减少 background information：ticks幼年期吃白鼠和其他物种，白鼠有细菌而其他物种没有 逻辑：其他物种数量增加——>（ticks更多食用其他物种而少食用白鼠）——>ticks被感染几率下降 很明显原文的gap是ticks会不会更多的食用其他物种，因为其他物种数量增加不等于吃的白鼠量下降 选项C：在幼年期ticks只觅食一次。当其他物种数量增加时，ticks食用到白鼠的几率就会下降。且只有这一次感染机会，那么携带细菌的ticks数量就和其他物种数量呈正相关对应关系了。 错误选项D：一个host animal（白鼠）可以成为很多只ticks的细菌来源。这个选项不能提供任何有关ticks会不会增加或者减少食用白鼠的有用信息，所以无关。

C 如果虱子只吃一次，那么其他食物品种多了，吃到白足鼠的概率就会小很多。但如果吃很多次，那即使其他品种食物多，也极有可能吃到白足鼠，所谓久走夜路必撞鬼。

C正确解释是：鹿虱只在幼虫时期吃一次。吃一次的话，如果其他无细菌老鼠多，吃到有细菌的概率肯定比之前概率降低。比如：原来丛林里有20个有细菌老鼠，20个无细菌老鼠，吃一次就吃到有细菌的概率就是50%，而增加一倍无细菌老鼠到40只，则吃一次吃到有细菌的概率变为33%
