Admin edit: Please do not post full questions on the discussion forums! Removed the question.

I chose (A), but it was incorrect because the actual correct answer is (B). I understand the reasoning behind why answer choice (B) is correct. However, I am concerned as to the actual fact that we are taught to consider the stimulus truth and to not question the premise, rather we ought to question the conclusions.

As this was an older LSAT - ought test takers still concern themselves with these types of questions (where the premise/speaker of said premise may be questionable)?

Hope to receive word from someone soon.
