再问gwd-4-7

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

看了前人的讨论还是不明白，请教思路谢谢！

这题的讨论很多

基本说明问题了

LZ是哪里有问题呢？

我应该是题意没弄明白所以看不出为什么B是对的。

those locations will not stay vacant for long 是因为C会进驻商业区所以填补倒闭商店的空白吗？

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."a new store"是指什么？B削弱了文中哪句话？多谢指教！

nondiscount colson open -> nondiscount store set A close -> new store set B open

discount SpendLess open -> discount store set C close

B: means B almost C, so now hardly any type of store can open since competation both from nondiscount colson and discount SpendLess. So weaken conclusion some other new store will open.
