In this activity we're going to give you a set of questions to answer. To make things more interesting, they're all about things you haven't read about in this module. Yes, we realize how delightfully sneaky this is of us, but we have confidence that using your library, the internet, and your own sharp wits you'll be able to uncover the answers to these questions. Short answers of about one paragraph will be sufficient for each question. Happy searching!
