单选题 United States advertising agencies are increasingly using interviews at shopping malls, called "mall intercepts", to test for advertising effectiveness, product concept viability, and consumer buying habits. Critics of mall intercepts maintain that the shopping habits of mall shoppers are not representative of those of the larger population.
Which of the following, if true, would provide evidence that most supports the critics' claim about mall intercepts?

A、 Some mall shoppers patronize more than one store in any given shopping trip.
B、 Mall shoppers, on average, spend 50 percent more time shopping than shoppers at other locations do.
C、 In the course of any year, 95 percent of all households in the United States have at least one member who does some shopping at a mall.
D、 Mall shoppers who use public transportation to reach the mall tend to have lower incomes than mall shoppers who drive to the mall.
E、 (E) Indoor malls often attract the customary numbers of shoppers even during inclement weather when outdoor malls are likely to lose business.

【正确答案】 B

【答案解析】[解析] 本题问题目的是支持该批评者关于“商城拦截”的宣称，因此读题重点应为最后一句话：“...the shopping habits of mall shoppers are not representative of those of the larger population”，可用关键词“mall shopper”来定位选项。若商城购物者比其他场所购物的人多花50%的时间购物，如(B)所说，那么就表明商城购物者确实与其他人不一样，不能够作为广大消费者购物习惯的代表，起到了支持作用，所以(B)正确；(A)的“some”不能去说明一般情况，所以起不到任何作用；(C)、(E)与段落推理无关；(D)做了一个与段落推理无关的比较。
