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 task 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 mathematics. (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.

(A) Most people who suffer from allergies or other such immune disorders are left-handed rather than right-handed (this has a logical flaw of A--> and hence B-->A). (B) Most left-handed mathematicians suffer from some kind of allergy ("most" is very strong in the context of stimulus). (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. (similar to A) (D) If a left-handed person suffers from an allergy, that person will probably be good at mathematics. (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. (logical flaw).

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 task controlled by the right hemisphere of the brain, and mathematical reasoning is strongly under the influence of the right hemisphere in most people.

(1) Left Handed --> suffer from immune disorders more frequently than right handers (2) Left Handed --> right brain generally stronger than right handers --> good chance reasoning ability may be stronger (math)

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 Eliminate: Inverse of statement #1. (B) Most left-handed mathematicians suffer from some kind of allergy Eliminate: Extending the scope. Statement #1 merely states that left handed persons have a higher chance as compared to right handers. (B) is an invalid statement because it is too strong. (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. Eliminate: Narrowing the scope. Statement #2 merely states that LHs may have a stronger right brain than those of RHs. The stimulus does not make value judgments like "above average" and "poor". (D) If a left-handed person suffers from an allergy, that person will probably be good at mathematics. Matches statement #2. (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. Eliminate: Invalid comparisons.

I think it shud be C for the answer to be D we will have to relate the 2 statements i think the 2 statements are independent Hence C looks to be the best choice.

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 task 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 mistaken reversal (B) Most left-handed mathematicians suffer from some kind of allergy most (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. no info on poor mathematical reasoning (D) If a left-handed person suffers from an allergy, that person will probably be good at mathematics. cant make this inference (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. yes. stimulus says left handers suffer more frequently from allergies than right handers. so left handers + right handers who suffer are greater than just left handers, similarly left hand + right hand allergy sufferers are greater than just left handers who happen to be unusually good in math

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 task 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. the opposite of this is true. (B) Most left-handed mathematicians suffer from some kind of allergy left handers having allergy and left handers with good mathematical skills are 2 separate things. It is not necessary that left hander will be mathematician and have allergy at the same time. (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. This sticks to left hander -> right brain -> good maths skills argument in the passage. Correct! (D) If a left-handed person suffers from an allergy, that person will probably be good at mathematics. again, maths and alergy is jumbled up! (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. (general) people suffering from allergies is nowhere implied in the passage. The passage talks separately about left and right handers

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 task 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 "Most" implies absolute value/numbers. No such information is given. (B) Most left-handed mathematicians suffer from some kind of allergy "Most" implies absolute value/numbers. No such information is given. (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. Reword: Among left handed ppl, more are good at math than bad at math. (D) If a left-handed person suffers from an allergy, that person will probably be good at mathematics. Reword: Lefties suffer from allergies. Lefties are good at math. Therefore, person with allergies is good at math. --> while this correlation is probably correct, logically, the paragraph gives no substantive proof of this. Its more implied than fact. (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. Reword: # of People with allergies > Lefties + People good at math --> this is an insane statement.

In this case, only C offers a concrete answer that doesn't go "too far" in coming up with a conclusion.

Does that make sense?
