I urge you all and your contemporaries throughout China to commit yourselves to finding answers to our century's great challenges of poverty, disease, and environmental degradation. I say to you, as I have said to students in the United States, and many other countries, go out and make the world better!
But I have spoken long enough. Now it's your turn. If you have questions, I will try to answer them. But I hope you may also have comments, so that I can learn from you.
Thank you very much.
