No one tried this question, so i wanna take a crack at explaining it.
The stem asks to resolve the discrepancy. Reading the stimulus, it seems the discrepancy is the idea that although alcoholic beverages are laden with calories, those who drink three or more alcoholic beverages, exceeding caloric intake necessary to gain weight, do not in general gain weight.
I prephrased this question by asking How come? Maybe the these calories are not stored in fat, but somewhere else. (hard question to prephrase an answer).
The answer choices:
(A) The stimulus explicitly states that these individuals exceed the caloric intake necessary to maintain their weight. Thus, this answer is wrong.
(C) Irrelevant, who cares about other people. I want to know why those that drink 3 or more alcoholic beverages do not gain weight.
(D) This is simply a regurgitation of info from the stimulus and does nothing to resolve the discrepancy.
(E) Irrelevant. The people we are concerned with DO take in more calories than necessary, we don't care about those individuals that do not exceed the caloric intake.
With 4 answers that were relatively easy to eliminate, i was only left with B.
(B) Correct Answer. This answer was not what I was expecting and caught me slightly off guard. But after rereading it, it does give a plausible explanation to why these individuals in particular do not gain weight.
I know this was an easy question, but i wanted to practice writing out explanations each question and figured this would be an easy one to start with. I would love any input and suggestions that would make my explanations more complete.
