请教一道逻辑真题

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?

1. Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened. 跟顾客无关


2. Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.


3. At present, the central shopping district has as many stores operating in it as it ever had.跟现在无关，讲的是5年内


4. 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.


5. 速度无关


6. Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.产品没有关系

不太明白作者的意图是什么？难道是B，意思：C店开了表明G店开了，导致discounting店关了？但是新开的点全是discounting的，不是nondiscount的，就跟原题目冲突。所以错了？

但是原来题目的结论是 those locations will not stay vacant for long。

答案应该是weaken这个才对，是不是？？

请牛牛指点啊

选B吧。

题目的结论是those locations will not stay vacant for long，即还会有新店开张。题目的理由是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，即以前有过一个先例Colson's，虽然有店因为竞争不过关门了，但是总有新店开张。问如何削弱？

要削弱，就是要想办法让原题的理由无法证明它的结论，在这里就要想办法找到Colson's和SpendLess不同的地方，使的两者无法类比。

B说Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.即竞争不过Colson's而重开的店越来越多的是折扣店。而Colson's和SpendLess的本质区别就是前者是非折扣店，后者是折扣店。竞争不过非折扣店Colson's的都改成折扣店了，而现在开的一家极具竞争力的SpendLess已经是折扣店了，竞争不过而倒闭的店要再怎么重开法？原文的理由自然就站不住脚了。
