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. Here is the post. Community memebr gung edited the question and presumably added the homework tag that was missing.
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?
