Hi mates,

IMO B

The argument says that if the animals that act as food to deer ticks larvae are not infected by the bacteria, the number of sticks with the bacteria will decline.

B says that a good question would be if the population of sticks could grow because there are more animals that are not infected.

I really hope this is the right answer...

OA?

Cheers

D is the best.

The conclusion states that if population of other species increases, number of infected ticks will decline as the only time these ticks get infected are during larva stage.

Depending upon the answer to question in D, the above conclusion can be stregthened or weakened.

The argument says essentially this:

-ticks get infected as larvae by feeding on infected mice.
-ticks can feed on all kinds of animals (different from mice) that do not carry the infection.
-if there were more of these other animals, fewer ticks would feed on the mice, so fewer ticks would get infected.

D isn't right, because it isn't relevant to the argument. D says, essentially, 'some ticks might get infected in some other way completely unrelated to what the argument discusses'. That might be true, but it doesn't matter; the number getting infected in the manner discussed in D isn't going to change based on the proposal made in the stem, so D is irrelevant. We need to evaluate whether the proposal in the stem is likely to reduce the number of ticks.

B is the best answer here. The above argument assumes that the total number of ticks does not grow substantially if you introduce new species for ticks to feed on. If the number of ticks stays the same, but many new animal species are introduced which cannot pass on the infection, you'd expect fewer ticks to feed on infected mice, and therefore you'd have fewer infected ticks. If, however, the number of ticks grows along with their food supply, you might have a lower percentage of infected ticks, but you might still have the same total number of infected ticks, because the total number of ticks is so much higher. That's exactly what B is getting at.

I dnt think I used that difficult language Actually study said that Ian's explanation was great.and acc 2 Ian , B shld be the ans(check his post above). But at the same time, study says D is the OA. that leads to conclusion whether the OA is D or B? I hope i made it simple this time.
