Q13:
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 whitefooted 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?
A. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
B. There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice.
C. A deer tick feeds only once while in the larval stage.
D. A single host animal can be the source of bacteria for many tick larvae.
E. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans.

I like C. Since the tick feeds only once while in the larval stage, more animals means the probabilty of them getting infected has become less.

OA is C.

Man I'm just getting tired of CR... Esp. when I have to look back at my wrong answers. Sometimes I just can not abandon my wrong logic and accept a new one.

Gotta go anyway. :twisted:

Answer is C.

Though E seems a straight choice but the informaton is provides is contradictory to what has already been provided in the passage. The passage says:

Lyme disease is caused by a bacterium transmitted to humans by deer ticks.

E talks abt other bacteria. We are not concerned about "other bacteria" here. We are only concerned with bacteria causing Lyme disease.
