Answer choice E

Why is answer choice E wrong here? I had trouble choosing between E and the correct answer. Thanks in advance.

@shafieiava,

Let's look at (E) and (C).

(E) says, "Unlike spruces or firs, most sugar maples are native to
areas that receive a lot of acid rain."

We're looking to resolve the paradox in the stimulus. The stimulus
makes a comparison between maples in acid-drenched, calcium-poor
forests with similarly situated spruces and firs. The problem with (E)
is that it doesn't tell us why a maple and fir, when placed in the
same poor situation, respond so vastly different to their adversity;
rather, it simply tells us that a maple is more likely to find itself
in that type of bad situation. Thus, (E) is out.

(C) says, "Spruces and firs, unlike sugar maples, can extract calcium
from a mineral compound that is common in soil and is not affected by
acid rain."

(C) starts off by comparing spruces and firs with sugar maples. It
provides us with just what we need by giving us a way in which sugar
maples are at a disadvantage in dealing with low calcium levels,
helping to explain the greater decline among sugar maples. Thus, (C)
resolves the paradox and is the correct answer choice.

Does this make sense? Let us know if you have any other questions!
