In this section, we try to drill what you have just learned so far into your brain that it will never leak out. How do we do that? - by making you think about what you've just learned.
(We know, it's a sneaky trick - but, by golly, it just works... so play along.)
In the next lesson, we'll start by reviewing what WE think are good answers to these questions. Until next lesson, think about what YOU think are good answers.
