104. Although the discount stores in Goreville’s central shopping district are expected to close within fi ve 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 fi ve 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 fi ve 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.
colson‘s是一个商店，只不过是一个nondiscount的。arguer通过类比，认为colson's开了之后把一些商店挤走了，但又有新的商店（姑且认为是ABC商店）开了，从而得出的结论被Spendless挤走的商店会有新的商店填补空缺。而选b是因为，colson’s挤走的商店都是nondiscount的，而之后新开的商店ABC是discount，所以不与colson's竞争得以活下来。而因为SpendLess是discount的，ABC也是discount的，而ABC竞争不过Spendless，也得被挤走，这样的话就又有空缺了。这时候无论新开的店是discount的还是nondiscount，都有很强的竞争对手，所以这些locations will stay vacant for long。从而weaken
