• A ‘presupposition’ is any statement that has to be true for there to be a true direct answer to the question.

• A presupposition is not just any assumption you might make in asking a question. For example, in asking someone a question, we usually assume that he or she knows (or probably knows) the answer. But this isn’t always the case: you might deliberately ask a question that you are sure the person can’t answer, intending to embarrass him/her.

• Most questions have one or more presuppositions, but not all do. Specifically, existence questions—i.e., questions of the form “Does X exist?”—do not presuppose anything.

• With these problems, the general instruction “pick the answer that comes close to the truth, the whole truth, and nothing but the truth” means the following:

  1. If two answers list genuine presuppositions, but one lists more genuine presuppositions than the other, the answer with more presuppositions is the correct answer;
  2. If one answer has only genuine presuppositions, while the other lists more genuine presuppositions but includes statements that aren’t genuine presuppositions, the first answer is correct.
