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.

俺们老师说这道题比较有争议,其实我当时做的时候就按照相关无关去排除选项做的。

事实:非折扣店C开张后的5年里(过去),由于竞争不过C的店倒闭后的地址上又开了新


推理:折扣店S开张后的5年里(未来),由于竞争不过S的店倒闭后的地址也会开新店

B选项的解释:如果C开张后,开的新店都是折扣店的话,则说明C的存在使得非折扣店已经没

有竞争力了,而折扣店还有利润空间;但现在的推测是S开张后,折扣店会倒闭,则说明S的

存在将使得折扣店也没有生存空间了,那么原来的地址上将不会有新店(折扣店由S统治,非

折扣店由C统治),削弱两者看似正确的类比性
