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. 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 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. OG解释说如果light一个和相关的相似性就可以削弱，但是小妹看了半天不知道这个答案是怎么得到的,而且即使知道了B是正确答案，也不清楚如何削弱。完全找不到结题的思路，各位大侠求助。

一道题的意思就是不管开discount store 还是non-discount store，都竞争不过那两个NB的大商店，都会关门大吉。所以，这些关门了的店的位置会一直空着（开啥都得关门），削弱了结论。
