求逻辑题目~~~NN们。。。谢谢哈

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窝藏 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? jj作者选C，但是我觉得是E！大家觉得呢？

1. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
   
   
   
   
2. There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice.
   
   
   
   
3. A deer tick feeds only once while in the larval stage.
   
   
   
   
4. A single host animal can be the source of bacterium for many tick larvae.
   
   
   
   

 E. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans

顶一下。。NN们帮忙~~

这个谁给我解释一下哈？

能不能到相应该板块去问问题..
另外能不能看下之前人的讨论..

Facts: lyme disease is caused by a bacterium transmitted to humans by deer ticks

Evidence 1: Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice

Evidence 2:certain other species on which the larvae feed do not harbor the bacterium

Conclusion: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

我逻辑也不好，感觉有个逻辑GAP， 然后排除它因，然后加强了结论。

请NN们指点。。。

E应该是无关选项，题干已经说了除了白鼠外，其他物种身上没有那种引起L病的细菌
和有没有其他细菌没关系

  A   Ticks 携带这种病毒对自己没有影响。——无关项     B   直接接触这种老鼠应该不会染病——无关项

  C.  A deer tick feeds only once while in the larval stage.  因为幼虫在能够染病的阶段职喂一次，那如果其他的未染病的物

        种多的话，用白老鼠喂养的机会就少了，染病机会就少，所以支持了结论。

  D. 无关     E. 与是否携带其他病菌无关
