A: That depends on how you define a question. Some people define a question as "a sentence of inquiry that requires a reply". Others define it as "the act of eating a kazoo whilst standing on one's head and playing a cheeseburger". We like to call the former "realists" and the latter "those people with whom, when engaged in conversation, it is best to just smile and nod and then slowly back away before breaking into a full run".
In short, the answer is pi.
