标题: [求助]GWD4-7 看了讨论，做错了一次，现在再看还是是不明白，请大家帮忙
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
这是我根据老帖总结的一段话：文章的意思是，虽然G这个地方的打折商店在5年内都预计会关门，因为和S这个打折店的竞争造成的，但是这个地方未必会stay vacant，就是说：这个地方不会没有竞争，不会缺乏竞争。引了一个例子，C店是一个非打折店，这个店开了5年了，而这个地方又开了一个新的商店，这个地几乎所有的商店都不能和C商店竞争。（即说明竞争又开始了）,而B说的是，新开的店是和C不一样的店，是一家打折的商店。那么与C来说就不是竞争了
看不大明白，请大家帮个忙，谢过

引用 chamcham 2007-6-26 15:56:00 的话 http://forum.chasedream.com/dispbbs.asp?BoardID=24&replyID=1771318&id=187990&skin=0

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

就是说打折店是斗不过sl的,其他店是斗不过cl的,那么即使说cl开了以后,有一个店也跟着建起来了,那么无论它是那种店,都斗不过sl或cl而再次倒闭,所以"有一个店也跟着建起来了"并不能证明该地的竞争减轻了,五年后地方可能会空很久
