Read this paragraph from "President Obama's Third Annual Back to School Speech.” But here’s the interesting thing. I still remember that ethics class, all these years later. I remember the way it made me think. I remember being asked questions like: What matters in life? Or, what does it mean to treat other people with dignity and respect? What does it mean to live in a diverse nation, where not everybody looks like you do, or thinks like you do, or comes from the same neighborhood as you do? How do we figure out how to get along?

How does this paragraph contribute to the development of the ideas in the passage?

A. It emphasizes how important ethics classes are in preparing for the future.

B. It shows that some classes can have a meaningful effect on a student.

C, It presents the questions that Obama will answer later in his speech.

D. It explains that many students have had similar experiences in school.
