"I think you just did."
"Quite correct. Then may I ask another question after this one?"
"You can ask me anything you want."
A question was a request designed to acquire information. A response to a question was usually known as an answer. "Who, what, when, where, why" (also known as the "Five W's") were the five most basic questions to determining facts to an answer. (TNG: "The Mind's Eye")
Captain Jonathan Archer stated: "Up until about a hundred years ago, there was one question that burned in every Human, that made us study the stars and dream of traveling to them, are we alone?" Archer proceeded to answer that question, continuing, "Our generation is privileged to know the answer to that question. We are all explorers, driven to know what's over the horizon, what's beyond our own shores. And yet, the more I've experienced, the more I've learned that no matter how far we travel, or how fast we get there, the most profound discoveries are not necessarily beyond that next star. They're within us, woven into the threads that bind us, all of us, to each other. A final frontier begins in this hall. Let's explore it together." (ENT: "Terra Prime")
In 2368, according to Captain Jean-Luc Picard, ever since the earliest wormholes were discovered, first year philosophy students were asked the question "What if one of those lives I save down there is a child who grows up to be the next Adolf Hitler or Khan Singh?" (TNG: "A Matter of Time")
