who should decied what books teens should read?

This is a answer for question number 5. i belive that the teacher should not be dissmissed becuase the teen while soon read it later why should they not be able to read it now? In our culture there is a lot of violence and drugs and many other things that we can see on a day to day bases. some of these thing are more graphic than what a book may describe and the parents who want to bane the book may let their kids wach! so why ban somthing that a person has to think about instead of siting them down to wach violent tv shows that dont make their brain acktive at all
