Boring AF. So vague, it can’t be wrong. You know, the answer that is so watered down and wishy-washy, it's basically saying nothing at all?
THAT'S YOUR ANSWER!!!
The GMAC wants to stay out of legal trouble. For this reason, any answer that is put forth as "true" must be totally indisputable. This means, incidentally, that it needs to be indisputably VAGUE as well. Vague statements are generally more likely to be "true" than specific statements.
This strategy is especially helpful when you are looking at two similar answer choices. One of them is clear, detailed and specific, while the other, stating the obvious, dialed-back, to which you might respond, "duh!"
