GMAT逻辑题目的讨论

　　大家常用的GMAT逻辑备考资料有哪些?OG是老师们推荐的首选。OG2016最新版出现了不少的新的GMAT逻辑题目，自然大家在练习的时候会有不少疑惑，今天留学360专家就其中的个别GMAT逻辑试题为大家稍作讨论，看看大家的观点有没有不一样的呢?

　　小编介绍的GMAT逻辑题目如下：

　　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 non-discount 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.

　　选B

　　留学360专家对这道GMAT逻辑试题的理解：

　　第一句话就是文章的结论：虽然那些在G的购物中心的折扣店被认为会在未来的5年内消失，因为S折扣商店的开启，但他们的位置不会空虚很久(言下之意应该就是他们的位置马上会被一些新的商店所取代)。

　　而第二句话就是得出以上这个结论的evidence：从C这个非折扣商店开业以来的5年内，所有在这个购物中心的商店都因为竞争不过C商店而关门了，但现在已经有一个新的商店重新开启了。(这个就是举个例子说明，商店们在被一个强大的竞争对手打败后，又会有新的商店冒出来，就像第一句文章预测的一样)。

　　B答案是说：在C这个非折扣店开业以来，折扣商店的重新开门的越来越多。言外之意就是说，因为C是非折扣店，所以恢复起来的都是一些折扣商店。而这次进来的S是一个强有力的折扣商店，所以说其他商店在倒闭后就不见得再会马上出现了，因为非折扣店有C这个巨头，而折扣店有S这个巨头，情况已经和evidence中的不一样了。

　　此题做错的原因个人分析：

　　主要是题目没搞清楚逻辑顺序。错误的把第二句话的内容当做要去weaken的对象，实则不然。第二句话说的是个现象，然后导出结论是第一句话，所以weaken的部分是 those locations will not stay vacant for long。
