B) A teenager asks her friends if they like a certain store. When they say yes, she declares that she likes it too, because she wants to seem cool.
C) A professor asks her students whether they believe there are instances in which genocide is "justified." She listens to their opinions and corrects them when they make inaccurate statements about history.
