This document provides potential answers to "why" questions, with some answers being valid reasons and others being invalid or nonsensical. Answers like "because I said so" or "for no good reason" would not adequately answer a why question, while answers like "so they can fly" or random numbers would not make logical sense. Answers providing an actual reason, such as "to learn" or "so that he can go to college", could validly answer a why question by giving a purpose or cause.
