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 descount department store that just opened, those locations will no 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.

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

Which of the following, if true, most seriously weakens the argument?
请NN帮忙讲解一下这道题的思路，谢谢~

题目不完整吧，没问题？？

此句结构为conclusion+premise.

翻译成中文即为：
虽然在G商业街内的  打折店  因竞争不过  打折店S 而将在5年内倒闭，但这些倒闭的店面位置不会空缺 （conclusion）。
因为在 非打折店C  开张5年内，一家新店  在之前因竞争不过C 而倒闭的店面内 开张了 (premise)。

显然，原conclusion是把 打折店与打折店进行对比，可是它用的premise却并没有说明 非打折店C 和 新店的关系；如果新店为打折店，是否无法作比较，进而无法佐证conclusion了？

LZ，不知俺表达清楚了木有~~~
