Then for the answers, they could put: Yes, No, I don't care, and I don't know. If they press I don't know, A video or text will appear on screen to show them. Then they run this servy for about 3 days mabye more. Once it is done, they collect all the answers from each question and see how much people said yes, no, or I don't care. (Btw, everything you said was spot on imo.)
