<p>I recently answered a multiple choice question on CV and although the OP did not label it homework it obviously was.  Should we try to give hints?  I had a hard time finding a way to suggest an answer without providing my rationale for picking a specific choice.  A moderator thought that my answer violated policy.  <a href="https://stats.stackexchange.com/questions/37940/probability-model-question/37942#37942">Here</a> is the post. Community memebr gung edited the question and presumably added the homework tag that was missing.</p>

<p>What should be done?  Should we just not respond to multiple choice questions?  Is there a way to be helpful with questions like this one without answering it?</p>
