A、Husband and wife. B、Teacher and student. C、Potential buyer and seller. D、Manager and his deputy. C推断题。对话二人在对一产品进行讨价还价，而且对话中还出现

W: We are quite interested in your nylon T-shirt. But I am afraid that your prices are much too high.
M: Not in the least. I should say that they are reasonable and quite in line with the market.
W: It’s just for the market reason that I suggest you make a reduction in price. Otherwise we can hardly go on with our discussion.
M: A reduction in price? I am afraid it’s out of the question.
W: Well,[10]we have made a market survey recently. More and more people are tired of wearing nylon T-shirts. They are more interested in cotton wear.
M: That’s true. But as the prices are already rather low, we can’t reduce much.
W: How much then?
M: We can reduce them by 5%.
W: 5%? When I say your prices are much too high, I don’t mean they are higher merely by 5 or 6 percent.
M: How much do you mean then? Can you give me a rough idea?
W: If you ask me, I would say that you should hold a reduction of about 12 percent.
M: You must be kidding. How is it possible to expect us to make a reduction to such an extent?
W: I won’t let you sell at a loss. If your prices are reasonable, I might place a large order. 5,000 dozen?
M: Er... Let’s put it this way. If you can order 8,000 dozen, I think we can make a reduction of 12 percent.
W: OK. We have come to an agreement on price at long last.
