Here’s another question that is looking for a yes or no answer. Statement (1) allows for both
positive and negative values of a, so it is not sufficient, and we can cross off A and D.
Statement (2), on the other hand, tells us that a is positive and must be a value of at least 3.
If a > 3, then the answer to the question stem must always be yes. Therefore, statement (2) is sufficient,
and our answer is B.
