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 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 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 stores in the central shopping district sell
types of merchandise that are not available at
either SpendLess or Colson's.

明白了 选B

我的理解是，作者试图建立这样一个类别推理：
原因：很多竞争不过非打折商店Colson的商店都关门了，但不久在这些关门的商店所在地址开了很多商店。
现状：打折商店G因为竞争不过S要关门了。
推论是：G的商店所在地址很快也会被别的商店取代。

问weaken。如果要两种情况可比，一定是G和S的情况要与C和与其竞争商店的情况一样，现在G和S都是打折商店，如果与C竞争的商店不是非打折（即打折商店），是否可削弱？
