Help, don't know how to do this question.

I've got an idea of how you could do this:-

1. Turn off TV.
2. Turn off games console.
3. Look under pizza boxes for text book.
4. Crack open text book.
5. Read about topic.
6. Think about topic.
7. Understand topic.
8. Answer question.

To achieve (8) you need (7). People on the web won't do that for you. Steps (1) thru (6) will do that. If not, should you be taking this course?
