Daming: Is New York the capital of the US, Betty?

Betty: No, it isn’t. Washington DC is the capital, but some people think the capital is New York because New York is a bigger and busier city than Washington DC.

Daming: I see. New York is more famous than any other city in the US, right?

Betty: Yes, I think it is. And which Chinese city is bigger—Shanghai or Beijing?

Daming: Well, Shanghai has a larger population.

Betty: Really? And which city is older, Beijing or Shanghai?

Daming: Well, that’s a good question! They are both very old cities, but Beijing is older than Shanghai.

Betty: That’s very interesting!
