【正确答案】 D

【答案解析】[解析] 19-22 W: Mr. Smith, is the number of complaints increasing or decreasing? M: There was a slight decrease last year. The highest number of complaints was two years ago when we received 7,300. W: Does the reduction mean that the quality of goods and services improving? M: I don't think so. It's probably due to the poor economic situation. Most people are simply buying less. W: Is there any change in the nature of the complaints? M: Not really. People are still complaining about the same thing. W: What do they complain about most often? M: Electrical appliances. Last year, we received 1, 809 complaints about them--25% of all complaints. Then there are complaints about travel agencies, photographic and sound equipment, and clothing--in that order. W: What sort of complaints do you get about travel agencies? M: Oh, they include anything from air tickets to accommodation. W: Are most of the complaints justified? M: About 90% of the complaints about travel agencies are justified. In other areas, investigation of about 50% of complaints reveals some kind of business mulpractice, but overall about 30% of the complaints are due to misunderstandings on the part of the consumer; the rest are too vague to be worth following up. W: How long does it take you to complete an investigation of a complaint? M: About 2 or 3 weeks for a proper investigation. We really need more staff. W: Thank you, Mr. Smith. M: My pleasure.
