求OG12 104题理解

lulud

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 disvount 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.
对于这道题，我想请问下，题目的前提和结论分别是什么？

以后再说

这道题的前提是一个不恰当的类比，得出的错误结论是those locations will not stay vacant for long。不恰当的类比是，把nondiscount店开张对周围其它店的影响和discount店开张对周围其它店的影响混同了

这个argument建立在一个类比之上。G这个地方的discount stores会在5年内因为这里刚开a Spend-less discount department store而关闭，但是those locations will not stay vacant for long。
正如在过去某个5年期间，Colson's这个nondiscount department store的开张让很多商店关闭，但之后其他新店又在这些倒闭的商店的原址开张了。
这到题目要注意看到前面说discount store用的是现在时。而说Colson's用的是完成时。
