“That’s what I love about what-am-I riddles or more open-ended riddles: there are always a certain set of traditional answers to those riddles, like with other riddles, but their answers are determined by whether or not they fit the criteria the riddle has, not just whether or not they fit the answer; it’s kind of like an evidence-based answer versus a multiple choice question. If I, for example, presented you with this riddle: “What is an impulse yet helps you think” (I just made that riddle up, actually), there is the traditional answer I thought of: nerve impulses. However, there are still other possibilities. For instance, a person could be all philosophical and say, ‘any impulse helps you think. Although you think recklessly, you technically are still thinking.’ With a multiple choice question, there would only be one answer, so you are very limited with riddles like that.” RiddlesOpen EndedWhat Am I Book:The Reformation Source: The Reformation
