wh-questions are different than polar questions, and in particular, saying "no" is infelicitous in most cases, and denying presuppositions is also different than answering a polar question with "no". From the Washington Post: Does sister need to know her abusive husband is why they stay away? Do landlords have to provide AC? Is your lamp the right size? The law also doesn't seem to work quite as well when the verb is a modal (e.g. should, can, could, ...).
