. Left-handed persons suffer more frequently than do
right-handed persons from certain immune disorders,
such as allergies. Left-handers tend to have an
advantage over the right-handed majority, however,
on tasks controlled by the right hemisphere of the
brain, and mathematical reasoning is strongly under
the influence of the right hemisphere in most people.

If the information above is true, it best supports
which of the following hypotheses?
(A) Most people who suffer from allergies or other
such immune disorders are left-handed rather
than right-handed.
(B) Most left-handed mathematicians suffer from
some kind of allergy.
(C) There are proportionally more left-handers among
people whose ability to reason mathematically
is above average than there are among people
with poor mathematical reasoning ability.
(D) If a left-handed person suffers from an allergy,
that person will probably be good at mathemat-
ics.
(E) There are proportionally more people who suffer
from immune disorders such as allergies than
there are people who are left-handed or people
whose mathematical reasoning ability is
unusually good.

nice i'm a lefty and didn't know we tend to have allergies and more mathematical reasoning (let's hope this is true for the GMAT!!)

my pick would be C

i feel the other answer choices are too narrow or too strongly worded

Only C makes good sense

C.

A: Most people? Maybe most people who suffer from such diseases are old people? This can't be drawn from the passage.
B: Nothing to suggest this in the passage.
D: Passage says ppl who are left handed tend to do better at math. This doesn't mean they will be great at math and suffer an allergy.
E:Nothing to suggest this in the passage.
