If X>-1, but < 0, what does that tell us? What that tells us is that X is a negative fraction. And that's the twist to this little problem, because you've got a negative fraction. Well, any negative that you square is going to be positive; therefore, we can readily see that B and E are our two answer choices. Now the twist to this is this. Let's say for instance that X represents -1/2. Well, if I cube -1/2, that takes me to -1/8. -1/8>-1/2. So X3 >than X; therefore, we have the answer B as the right answer, where X2 >X3, which is greater than X.
