Hi, Question on the CAT is: If m, n, and p are integers, is m + n odd? (1) m = p^2 + 4p + 4 (2) n = p^2 + 2m + 1 Now, when I solve (1), then I get that m = (p+2)^2 Thus, if m is Odd, then p is Odd, and if m is even, then p is Even. But the answer explanation says that it cannot be determined. Please...
