We are reading the outsiders in class, but i don't understand theme. can anyone ?

The theme in a story is an idea that readers can see multiple times throughout the story. Sometimes themes make the reader question the actions of the characters-- such as deciding right from wrong. Some of the main themes in "The Outsiders" is the divide between the rich and the poor, empathy, the protecting of childhood innocence, honor and individual identity. 

Let me know if this helps! :)

The following options can be used to write an exposition paper as it requires the student to investigate an idea, evaluate evidence, explain more the idea, and set forth an argument concerning that idea in a clear and concise manner. 
A. The Best Way to Buy a New Car
B. The Way to Shoot a Basketball
E. Our School Should Build a New Gym
F. The Death Penalty Should be Repealed
