实在是看不出B选项如何 waekens the argument啊....

原题是这样的:

654. Although the discount stores in Goreville’s central shopping district are expected to close within five years as a result of competition from a SpendLess discount department store that just opened, those locations will not stay vacant for long. In the five years since the opening of Colson’s, a nondiscount department store, a new store has opened at the location of every store in the shopping district that closed because it could not compete with Colson’s.


Which of the following, if true, most seriously weakens the argument?
(A) Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened.
(B) Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.
(C) At present, the central shopping district has as many stores operating in it as it ever had.
(D) Over the course of the next five years, it is expected that Goreville’s population will grow at a faster rate than it has for the past several decades.
(E) Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.

版上曾经有这么个解释，贴上来供LZ参考哈~~

解释部分的意思：题干中的arguement的逻辑是建立在两个case相似，可进行比较的基础上，只要能证明两个case不可比，则可削弱此逻辑推理。选项B指出在colson的案例中nondiscount的店导致了周围的店关闭后被discount的店取代，而在spendless的案例中，这个需求（对折扣店的需求）不再存在，因此两案例不可比。

这个是解释部分的意思，自己的理解是：
colson案例中，nondisctount店关门，discount店取而代之；而在spendless案例中，本来就是discount店，不一定有比discount更吸引人的业态能够在那里成功，所以未必旧店关门后会比新店取代。
