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？作者: merrimack 时间: 2010-8-27 22:21

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。作者: 以后再说 时间: 2010-8-28 00:22
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
