单选题 The recent upheaval in the office-equipment retail business, in which many small firms have gone out of business, has been attributed to the advent of office equipment "superstores" whose high sales volume keeps their prices low. This analysis is flawed, however, since even today the superstores control a very small share of the retail market.
Which of the following, if true, would most weaken the argument that the analysis is flawed?

A、 Most of the larger customers for office equipment purchase under contract directly from manufacturers and thus do not participate in the retail market
B、 The superstores" heavy advertising of their low prices has forced prices down throughout the retail market for office supplies
C、 Some of the superstores that only recently opened have themselves gone out of business
D、 Most of the office equipment superstores are owned by large retailing chains that also own stores selling other types of goods
E、 The growing importance of computers in most offices has changed the kind of office equipment retailers must stock

【正确答案】 B

【答案解析】[解析] 本题让我们去削弱段落最后一句话，且读题重点放在如何去驳斥原因。“since even today the superstores control a very small share of the retail market. ”(B)直接驳斥了原因；(A)、(E)与superstore无关；(C)的some为个案，并不能反对一般；(D)虽涉及superstore，但与“市场份额”和“价格”均无关，所以必然不对。
