is |xy| > x^2y^2?
1. 0<x^2<1/4
2. 0<y^2<1/9
in this question C looks like an obvious answer. But how do we recognize statement 1 and 2 not eing sufficient by itself? Other than "statement 1 says nothing about Y, so it can't be sufficient. We can't assume that all the time. How do we recognize in statement 1 and 2 that it is not enough.
THis question came as a "hard" question so since C was so obvious I was scared to pick it. I hate to brute force statements 1 and 2 because it gets so annoying and stressful during a timed exam.
Perhaps there is a way to simply this question?
