请教OG12-104

104.Although the discount stories 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 tha 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 dacades.

E.Many stores in the central shopping district sell types of merchandise that are not available at either SpenLess or Colson's.

此题答案选B。题目不是很懂，请NN能指点指点，十分感激~

个人理解仅供参考哈

Although the discount stories 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. 我想这句话中划线的部分是难点， those locations refers to the locations of the discount stories, 它告诉你折扣店关门了，但是很快会有其他的店铺顶上。

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. 划线部分说在 Goreville’s central shopping 的店铺之所以在五年内会关门是因为Colson 的缘故。

题干的argument =Goreville’s central shopping 的店铺关门是因为Colson 的原因，
            关于Spendless 是第三者和稀泥的。

那么要weaken ，
            就要提到G和C ，所以ACDE都和主题没关系，
                B对是因为G和C没有可比性，一个是折扣店，一个不是；
            就好是说苹果卖的不好，是因为梨卖的好一样。

很感谢 但是还有点不明白， 题中是说discount storie in sGoreville's central shopping 预计在五年内消失是因为S的竞争，而又说在 Goreville’s central shopping 的店铺之所以在五年内会关门是因为Colson 的缘故。那这不是矛盾了么，店铺的减少到底是因为G还是S.折扣店关了之后有店铺顶上，而这些店铺又因为C的原因关门了，题目到底在说什么呢

 最后再弱弱地问下 到底什么是argument 呢？其实这个问题很困扰我 再次感谢！

好怪的题目，我也研究了半天。终于有了些眉目。关键的地方，我觉得，还是要明白Colson那部分只是个类比，作为论据，如果和Spendless那部分扯在一起会很混乱。

前提：很多discount stores会因为S的开张而倒闭，S是discount store

结论：空的店铺会被补上。

论据：Colson开张后五年，新的商店就取代原来C竞争掉的商铺的位置。

B选项：这些新开的商店都是discount stores

也就是说ds对于C来说还是有优势的，所以ds可以在C周围存活下来。这二者是有差异。有差异，所以能活。

但在S周围，同质的ds店被挤掉，新的ds店还会不会去开在那里取代原有的位置值得怀疑，至少后来关于C的例子不足以证明。故weaken.

argument我理解就是提干讨论出的结论。

个人意见哈，有待讨论。
