Q:Given the question "Why does Steve keep empty cans?" and the answer "He wants to sell them to the dustman.", write a conversation that might have happened.
A:
W: Do you collect cola cans, Steve?M: No. Why do you ask?W: You have so many empty cans here.M: Well, my mum wants me to keep all the cans, so that we can sell them after a while.W: Aha, you are going to make a millionaire of yourself sooner or later with all those cans.M: You bet I will. Well, that's not the point. The point is we separate reusable things from other rubbish. We have to pay the dustman for dealing with rubbish, but if we sell him these cans and other reusable material we pay less.W: That sounds a clever idea. Now what are reused in China?M: Metal, plastic, paper, books and the like.W: Just as we do back home in the States.M: And to avoid waste, the government is limiting the production of goods that can be used only once, such as bamboo chopsticks. For example, all the fast food boxes should be made of paper instead of non-reusable material.W: That will surely be helpful for a clean environment.
