This is not an exercise, which is probably the reason you're having trouble figuring out what to do with it. The citation that you refer to says an exercise consists of directions, examples, questions and answer choices. There are no examples, questions or answer choices here. There are no blanks to fill in, no sentences to complete, no columns to match, no errors to correct. In short, all that is here are directions and this is simply a list of directions, things to do . Explain, describe, write, with nothing following. Treat this as a nested list.
