IMO B

IMO the ans to b impacts the conclusion of the argument

Definitely a head-scratcher!
But the answer should be B. Choice C looks like the trap answer.

Explanations pls!!

Hi!

Well, we learn that the deer ticks, as larvae, pick up the bacteria that causes Lyme disease by eating these infected white-footed mice.

But do they eat these mice because they like the taste or because they don't have any other source of food available?

We don't know...but this is what we would really want to know in order to evaluate the claim that we could stop (or slow down) the deer ticks from picking up the bacteria by increasing the supply of infection-free food sources.

IMO D

good question!!

But do they eat these mice because they like the taste or because they don't have any other source of food available?

Pardon me. This should read : "But do they eat these mice because they like the taste or because the supply of alternative infection-free food sources is limited"?

D seems to be the best choice here
