This is the resources page, and will serve as your "answer page." You must read most of these links before you can attempt to answer most of the questions on both the task and test pages. Even if you don't like to read, I think that you will find most of these articles informing and interesting, especially if you are interested in this topic. I learned a lot of things while reading them, that I never would have even thought to be true!
