Textual feedback when answering

When I go through the quizzes, I get a right or wrong. What I am craving for is a why. Why is my answer incorrect? Why is it correct? That'd be far more useful then a simple yep, that's right or no, that's wrong.

Edit: Can be ignored. Just never noticed that there is text because it was below the fold and there wasn't anything to indicate that there's more.
