标题: OG CR107题请高手来帮忙解释下
107. 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.

(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.

哪位大侠来帮忙解答下吧，答案是B，但是有一个疑问，个人认为conclusion是those locations will not stay vacant for long，所以不管这个店是什么性质，有没有竞争关系，只要有新店开出来不就可以了么？

非大虾，说下我的理解。
原题分为两个部分，第一部分是现状和结论，第二部分是论据
现状：因为竞争不过新开的discount department，所以discount store在五年内可能会倒闭。
结论：空门面不会闲置太久。
论据：在五年内，因为竞争不过nondiscount department而空出的门面因为新店的开张没有被闲置。
作者的逻辑其实就是希望用类似情况的第二件事情推出第一件事的结论，然而两件事情的差异就在于使大量store倒闭的一个是discount department一个是nondiscount department。显然discount department更难竞争一点，抓住这一点差异就可以对原结论进行削弱，也就是B答案：新开的敢和nondiscount department竞争的是discount store，而第一件事新开的店要和discount department竞争，显然不能类比

现状：因为竞争不过新开 ...

我明白你的思路,关键点是"nondiscount"要比"discount"点难竞争.

我在仔细研究了下题目之后觉得应该是这样的......
background: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,
conclusion: those locations will not stay vacant for long.
premise: 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.
我一开始忽略了一个点,就是background和premise中的the shopping district应该是指一个地方, 如果一些店因为竞争不过nondiscount店最终是被discount店取代的,那被spendless discount击垮的店就很难再被开出来了,因为没有需求了.如果这些是发生在一个shopping centre里,那就说得通了.
