Copyright and Fair Use SR

I thought that the most interesting answers came from questions 2, 9, 11, 12, 15, 16, 17, and 18 because a lot of them had to do with the simultaneous use of programs during class or in school. I thought that this quiz showed there were a lot of little loopholes in copyright laws and is not as cut and dry as I had thought. Now that I have taken this quiz, I do not feel like I know any more about the laws, and am just more confused by what can and cannot be done in a classroom setting.
