OG 104

futureflow

104. Although the discount stores in Goreville’s central shopping district are expected to close within fi ve
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 fi ve 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 fi ve 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.

答案是B，这题貌似是考错误类比。我看了几遍才看懂之后又不懂为什么B对
有没有人能列一个逻辑简图或说说推理过程呢？  还有答案为什么对呀？

现在 新开了spendless折扣店，预计周围的折扣店5年内会倒闭，但是店面不会空很久（即会很快开新店）。
这个预计是因为过去的例子：
5年前，Colson非折扣店开张，周围的非折扣店倒闭，但很快开了很多新店与Colson竞争。（B选项强调新店是折扣店）


问削弱


(B) Increasingly, the stores that have opened in the central shopping district since Colson’s opened
have been discount stores.
在Colson店开张后开的新店都是折扣店。



Colson后这些新开的店之所以可以和C竞争，是因为：C是非折扣店，这些新店是折扣店
现在开了家大型的折扣店，周边的以前的小折扣店倒闭后，就不可能在有新店抗衡了，所以削弱结论

芷宣啊，我刚看到了另一个帖子上你的回复。那些新东方规则不要再用了，很呆板根本不够解决gmat的，还是要锻炼实力啊。还有语法如果仅靠新东方规则的话也很危险

futureflow

真饶死了，终于明白了。 这是什么逻辑，很OG但非mine, 要尽快熟悉一下 ~  

aomeisoft7你是怎么跟OG的逻辑思维靠近的呢，在你们两者挨不着边的情况下？

这题你一下就看出是什么逻辑了吗？

我还是觉得这题目本身有问题，或者选项有问题，才导致我看不懂。
理由如下：
现在 新开了spendless折扣店，预计周围的折扣店5年内会倒闭，但是店面不会空很久（即会很快开新店）。
这个预计是因为过去的例子：
5年前，Colson非折扣店开张，周围的非折扣店倒闭，但很快开了很多新店与Colson竞争。（B选项强调新店是折扣店）
题目的结论是想说discount store倒闭的地方，会很快开新店，但并没有说一定是和SL竞争的。那些vacant的地方同样也可以开非折扣店，就像Cl那个区的情况一样。（同样，CL的例子，题干也没说新店也是非折扣店啊） 所以加上B选项后也没有削弱到啊。
所以我一直把重点放到“开新店”上，而不是“会不断的开店竞争”

我开始的时候做一样也不会做
看的晕头晕脑的，勉强理解前人讨论的解释
有些题目的逻辑是很奇怪
也只能被OG强压进去了
千万别用自己的思维=.=
GMAT逻辑没有常识可言...

不是啊，你可以看看我所有的帖子，只有你的问题用了所谓的技巧，别人的都是很踏实的做题的，你这两道问题确实很有难度，肯定是高分区的题了，弄清楚再做根本没有时间的，用技巧的话except那个技巧纯粹扯，但是many much some确实比较主观是可用的
