【正确答案】 A

【答案解析】[听力原文]
You"ve probably read in the newspapers many times such and such a company was recalling some product. Have you ever wondered how effective those recalls are? Well, that depends on two main factors. First off, it depends on whether the recall involves safety factors or not. A company that makes products for children recently recalled two items, a baby carriage and a child"s swing set. The baby carriage was recalled because of a flaw in the front wheels that made it difficult to turn, but this flaw was not dangerous to children. Only 10 percent of these baby carriages were recalled and replaced. The swing set, however, contained a faulty part that could cause it to tip over, possibly causing injury to children. Over 40 percent of these swing sets were recalled and replaced. The other factor is cost. The more expensive a product, the more likely it is to be successfully recalled. This is true in part because new owners are more likely to register expensive products, and it is therefore easier for the company to contact them. The most successful recalls, of course, are those involving expensive items with safety issues. A leading motorcycle manufacturer successfully recalled a remarkable 90 percent of the motorcycles manufactured at a particular plant in a particular year because they had defective brakes.
