We have been talking an in immense detail about adversity and challenges by reading books like perspolis and fahrient 451. These novels are about people going threw adversity because the government is ignorant or plain punitive about change. Along with antagonists comes protagonists to fight for something they truly believe in.

Challenges are that people try to subjugate for the better. Just like marji and her family is trying to do by demonstrating against the government of Iran. Including montag living in a society were books are illegal and he soon finds out that book have the signifiance of knowledge and have more meaning than people assume.
It is inenvitable to inquire challenges all threw life, its not how painful it can be important, but how you conduct yourself through out the life lesson.
