List some important ideas Johnny trenmain includes. Why did you choose those ideas?

Jonhny Tremain is a historical novel for teen-aged readers. Some of the ideas presented in the novel are:

* Apprenticeship and Sacrifice: I choose these ideas because they a good way of teaching teenagers about the importance of making an effort in order to get what they want.

* The tension between the Whigs and the Tories: I choose this idea because I find it important to be involved in political and historical issues, even if they are from the past.
