Lyme disease is caused by a bacterium transmitted to humans by deerticks. Generally, deer ticks pick up the bacterium while in thelarval stage by feeding on infected white-footed mice. However,certain other species on which the larvae feed do not harbor thebacterium. If the population of these other species were increased,more of the larvae would be feeding on uninfected hosts, so the number of ticksacquiring the bacterium would likely decline.
Which of the following would it be most important to ascertain inevaluating the argument?
A. Whether populations of the other species onwhich deer tick larvae feed are found only in areas also inhabited bywhite-footed mice
B. Whether the size of the deer tick populationis currently limited by the availability of animals for the tick's larval stageto feed on
C. Whether the infected deer tick populationcould be controlled by increasing the number of animals that prey onwhite-footed mice
D. Whether deer ticks that were not infected aslarvae can become infected as adults by feeding on deer on which infected deerticks have fed
E. Whether the other species on which deer ticklarvae feed harbor any other bacteria that ticks transmit to humans
这个是这个月的一条逻辑狗,怎么感觉哪个答案都好像不对呢?跪求大神指点一下~~~
