听力原文：W: Can you give a discount for this microwave oven? M: I can't reduce it for you. The price can be only as the tag shows. W: Come on. Cut down the price just a little. I can buy this in another store, but I choose to buy it with you as your store is nearer to my place. M: Well, I do have to meet a quota in order to get my commission. OK. I'll take off, let say, fifty dollars. How does that sound? W: Oh no. I was thinking maybe more in three digits. Something like two hundred ? M: Please. That's way off too much. Seventy-five, no more no less. W: Give it two zeros like a hundred. I feel luckier with zeros. M: Alright, eighty is my last offer, anything higher than that will eat into our profits already. W: OK. I can settle for that. Be sure to have it securely packaged. What does the woman want to buy?A.
