If n and p are integers, is p > 0?
(1) n + 1 > 0
(2) np > 0
Answer should be C - both statements together are sufficient.
From what I can tell, (1) is not right on its own because n could be -2, for example, and the problem would not work. In (2), if n and p are both negative, the scenario could also work, but the two equations would then not work together. This is why I'm a bit confused about this one. I thought that E would be the answer.
