104.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 non-discount department store,a new store has opened at thelocation 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.B
(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 storesin the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.
我不理解的是这两个案例之间有什么联系,他们都是Gorevile's central shopping district的店么.我知道他们是类比.spendless和colson's难道开一起了吗,要么为什么在C旁开的新店不能是discount store
