Please Respond

I have a quick question for all of you out there reading this. On a "yes" or "no" open-ended question which only asks for a response if the answer is yes, is it fair to recieve a "0" for answering "no" to the question? example: Identify whether or not you have... If you have explain. Like the title says, please respond. I would like to know your thoughts although it seems quite obvious to me, maybe I'm wrong. much love becky
