Read the excerpt from "President Obama's Third Annual Back to School Speech.” "So all of you have a lot on your plates. You guys are growing up faster and interacting with a wider world in a way that old folks like me, frankly, just didn’t have to. So today, I don’t want to be just another adult who stands up and lectures you like you’re just kids -- because you’re not just kids. You’re this country’s future. You’re young leaders. And whether we fall behind or race ahead as a nation is going to depend in large part on you. So I want to talk to you a little bit about meeting that responsibility.
What argument does President Obama make in this excerpt?

Young people today face a lot of pressure and responsibility.

The students of today will be running the country eventually.

The world today is more complicated than it was in the past.

Adults should stop thinking of young people as just children.
