if n and p are integers, is p > 0?
(1) n+1 > 0
(2) np > 0
if -1 < n < 0 and p is negative, then both equations are correct
if n is positive and p is positive, then both equations are correct
therefore, it is impossible to determine whether p > 0.
However, the correct answer is (C). What am I missing?
