Yep. When configuring a quiz, is it possible to add in a text field where the administrator would be able to add in some text (a comment) about the right answer. So when the user selects the right answer, the result is returned to them along with the comment.
This would be kind of educational if you wanted to expand a little more about the answer to the question. For example:
Are apples red?
Answer: Yes
Correct Answer - Yes.
Explanation: Apples come in many different colors, one of which is red.
Hope I didn't confuse your further.
