This question can cause a teacher to feel put in the role of a demagogue whose ``wants'' are mysterious to you. They may answer, ``I want the correct answer!'' If the question is incomplete or ambiguous, your teacher will not mind clarifying the question, and you should make it your responsibility to come forward (but don't ask this question if you only want to know if your solution is correct). You may have a better understanding of the question than you say, but you may just not be able to solve the problem. Sometimes you can explain on your test how you are interpreting the question, and respond accordingly.
