Although the discount stores in Goreville’s central shopping district are expected to close within ? 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 ? 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 ? 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. 答案是B 能说下这道题的解题思路么
我是这样理解OG的解释的 出题者是在拿两个实例在对比,把C店例子当作evidence去支持those locations will not be vacant long。所以any information that brings to light a relevant dissimilarity would weaken the argument. S店是discount的, C店是Nondiscount的。在B选项中,说the scores that have opened in the central shopping district since Colson's opened have been discount stores, 其中把C店nondiscount和discount混在一起书,破环了两个单独实例的逻辑可比性。所以B最能削弱。 不知道这样理解可不可以?
