16.
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 我觉得A对啊。请NN指点

不是牛牛。以下是我的见解，请指教。
题干说大型超市的低价格把很多小公司逼出了办公用品零售市场。但是这也
不对，因为大超市只占很少的市场份额。问削弱。
A是无关的。说大买家直接从厂家购买，这与上面的两个卖家都无关啊。
B说大超市的大型广告把价格逼下来了。正好削弱。

conlusion is that retail business isn't impacted by superstores low price strategy.
B says retail business is forced to decrese the price under the pressure of superstores policy
A says there is some other reason caused drap in the amount of purchase office-supplier. It is a good weaken choice but not fit to flaw question.
Flaw need us to follow the thinking of author to find out the incorrectiveness in the logical chain. Every element that does not invlove the argument is not the vane of the answer and must be eleminated instead.

哦 谢谢两位啊。
是不是B正好削弱结论。而A只是削弱了其中的提干的内容，和结论没有之间关系？

楼上的,你是不是把superstore理解成manufacture啦?题干的逻辑是这样的,superstore占的市场分额少,所以superstore对市场的影响小,要进行weaken的话,就得说占得市场分额少并不意味着对整个市场影响小,B就是个很好的weaken:虽然市场分额小,但superstore 通过做广告促销的方式影响了市场价格. 再看A选项,如果把superstore当成manufature的话,A也对,是另外一种weaken的方法:虽然superstore 零售市场小,但是由于和许多公司直接签约, 总的来说,市场分额很大. 但是superstore这里不是Manufacture所以不选A
