参考答案

正确答案:C
C 解析:Again, this problem is looking for a yes or no answer. Statement (1) doesn't tell us anything about the May price, so it is not sufficient. We can cross off A and D.
Statement (2) doesn't tell us anything about March, so it is not sufficient and we can cross off B. With both statements together, we know relative prices, and no matter what numbers we were to assume, the May price ends up slightly higher than the March price. So the answer is definitely no, meaning that both statements together are sufficient, and the answer is C.
