OG12-CR-104.
Although the discount stores in Goreville's central shopping district are expected to close within five years as aresult of competition from a SpendLess discount department store that just opened, those locations will notstay vacant for long. In the five years since the opening of Colson's, a nondiscount department store, a newstore has opened at the location of every store in the shopping district that closed because it could not competewith 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 SpendLessstore opened.

(B)Increasingly, the stores that have opened in the central shopping district since Colson's opened have beendiscount 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 ratethan it has for the past several decades.

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


我的想法
论点是：those locations will notstay vacant  
weaken它的话 可以strengthen    those locations  will stay vacant

排除法可以做出来是B
但是想不明白为什么是B
还有在这里折扣店到底和折扣店有什么关系，是怎么weaken的？

尽管G购物中心的折扣店在5年内被预期关掉，因为来自刚开的S折扣店的竞争。那些店面不会空太久。在5年内自从C（不折扣店）开业，一个新的店开业了在那些曾经因为竞争而倒闭的店的地方

我来解答你的问题吧。。。B选项之所以weaken了argument 是因为该选项指出了 “为什么过去的经验不能apply到现在的新情况上”
因为在过去Colson开业之后，把当地的一些其他小店给弄破产了，但是后来周围陆陆续续，一些新开张的折扣店逐渐在这个区域繁荣起来了。（这里面其实有一个assumption，即折扣店跟非折扣店相比，具有天然的竞争优势。）
但是这次，Spendless店本身是个折扣店，而且是个大型的很牛逼的折扣店。这个大店的开业，会把现存的这些折扣店（Colson开业后替代了原先非折扣店的折扣店）给排挤下去。
因为这两次替代过程，本质上完全不同，过去的经验无法用来运用和解释现在的情况。现在的这些小折扣店，明显面临了更加严酷的竞争环境。所以当他们破产以后，也很难有什么其他店替代他们。（除非出现了一种比折扣店还牛逼的店）、
