B. they wanted to know what inspired an act of violence

Explanation:

Although there isn't enough information, I'm assuming this refers to the study made by Stephen and Rachel Kaplan. Their study was aimed towards explaining the impact environment has on one's (or population's) happiness.

The idea started long ago, after John F. Kennedy's assassination and the situation that followed.

They wanted to know what was the cause of such a violent crime and tried to link that to the unhealthy environment, or in other words, could that violence be the consequence of an unhealthy environment.

Their study was supposed to determine what are the characteristics of a desired environment, what impacts it has on people and what conditions it needs to meet in order to contribute to the well-being of the population.

yes, they are. i think.

rudy is the nazi ideal, unfortunately for the nazis his ideal comes in the form of jesse the complete opposite of those who embrace the idea of white supremacy. over the course of the novel, rudy learns that he wants nothing to do with the hitler youth, and because of this his parents are forced to make a bargain; rudy's father is forced into the military, so that his son can remain home.   both liesel and hans influence that young man that rudy becomes. following han's example, rudy puts aside his own hunger to risk his life so that the jewish prisoners might have bread to eat.
