[求助]GWD4-7一头雾水，求救

Q7: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?

1. Many customers of Colson’s are expected to do less shopping there than they did before the SpendLess store opened.
2. Increasingly, the stores that have opened in the central shopping district since Colson’s opened have been discount stores.
3. At present, the central shopping district has as many stores operating in it as it ever had.
4. 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.
5. Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson’s.

恩 我也赞同b 同时感到这题满奇怪的

偶逻辑猪头 看完题目么有任何方向...

同意B

本题的意思是：

CL开始后，一种新的店很快就建立起来了。－》SL店开始后，也会有别的店建立起来。

CL 和SL的共同点就是比以前的有竞争力

削弱，找出两种情况下的不同点：所以选B

nondiscount colson open -> nondiscount store set A close -> new store set B open

discount SpendLess open -> discount store set C close

B: means the set B is almost the set C, so now hardly any type of store can open since competition both from nondiscount colson and discount SpendLess. So weaken conclusion some other new store will open.

E is irrelevant since only talk about discoutnt stores which will close by SpendLess. The store sell different stuff and will not open is not discussed.
