OG 12 104

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.

Argument Evaluation
Situation Due to competition from a recently opened SpendLess discount department store, discount
stores in Goreville’s central shopping district are expected to close within fi ve years. But
those locations will not be vacant long, for new stores have replaced all those that closed
because of the opening fi ve years ago of a Colson’s nondiscount department store.

Reasoning Th e question is which option would most weaken the argument? Th e arguer infers that stores
that leave because of the SpendLess will be replaced in their locations by other stores
because that is what happened after the Colson’s department came in. Since the
reasoning relies on a presumed similarity between the two cases, any information that
brings to light a relevant dissimilarity would weaken the argument. If the stores that
were driven out by Colson’s were replaced mostly by discount stores, that suggests
that the stores were replaced because of a need that no longer exists after the opening
of SpendLess.

B为正确答案，我首先是passage就没弄明白，没看懂，哪位能帮忙解释一下吗？

不知道这几个商店到底是什么关系，是在同一个地区，还是把两个地区的商店做了个对比。

另外OG的解释也没弄明白。

我也是，那位高手解答一下
