请教:补充材料178

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.


答案是B,但是我不是很明白B是怎样削弱那个argument的,而且既然那个argument利用市场份额小这一点作为上面分析的缺陷的话,那我觉得D才是weaken这个argument的呀???

题干先提出了某种分析:超级市场的high sales volume 导致价格下降。然后又反驳说这个分析是错误的,原因是超级市场的占有比率小。题目问什么能削弱那个反驳,意思就是削弱那个“市场占有率少”这个原因。 答案B是属于他因削弱。就是找出一个解释价格低的真正原因。D某种程度上只说了市场占有率的问题,但是它没有能解释价格低这个问题。

D中的"Most of the office equipment superstores"与原句中的"small firm" 不是一个概念啊, 所以D只是表述了一个与原句论证无关的状况.
