Do you think you can help me out? ,M: Sure, what's this project about? ,F: Well, I should interview someone that I admire about their jobs. ,M: Well, I am an expert when it comes to my job. Accounting is a respectable job and one that I am always happy to talk about. ,F: Dad, I know how much you love your job. It isn't that I don't admire you. But what I was hoping actually was that you could speak to Mr. Chung, your diving friend, and see if he would agree to an interview. Diving for a living sounds cool. ,M: I see. That's a great idea.

Example Input: M: I have noticed that a lot of people around here are very healthy and hard working.

I think most people are just more aware than before whether it is about themselves or the world. There is so much information out there. People are less ignorant than they were before.
(A) M: People in China are more positive than before, because they cannot access to information. (B) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said.

Since people have access to more information, they become wiser than before.
