Although the discount store 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 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 stroes.
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 Gorevile'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.

这题什么意思呢？一直没弄明白，答案选B。
题干是说过去一个Colson's的非折扣店开了，周边不能和它竞争的店关闭了后又开了新的店，以这个为例子推导出说Spendless discount 开了后5年内关闭的店也不会荒太久吗？

能不能有同学讨论一下，我很迷惑A B 项哈。谢谢啦！
