标题: OG 104
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

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

题干
尽管该地区的折扣店都将5年内倒闭，因为来自刚开的S的竞争。但是那些店面不会被空置很久。非折扣店C开张后的5年内，在原来因竞争不过C而倒闭的店面上新的店开张了。

逻辑题关键就是看题干的推理过程，逻辑链有了任何题目都是迎刃而解。这个题目的难点在于结论和论据都不明显，它没有一些连词来暗示结论与论据。其实这就是一种归纳类比的推理。

结论是尽管由于新开张折扣店S的竞争，折扣店都会倒闭，但是它们留下的店面不会空置很久。通过以前类似的案例论证：非折扣C开张，周围的店也倒闭了，但是5年内那些空置的店面上就有新店开张了。归纳得到：现在折扣店S开张，周围的折扣店虽然5年内会倒闭，但是店面不会空置很久。

B选项，C开张后，新开张的都是折扣店（即没有一个非折扣店再开张了）,那么实际上类比到S，周围折扣店倒闭后，没有一个折扣店会再开张了。也就削弱了原文的结论

many much some cetain 之类的确实是正确的概率较小，没时间的时候可以用来排除。那些所谓的正误规律虽然不是全对的，但是要知道考试的时间是比较紧张的，各种情况也都是可能发生的，遇到时间不足的情况必须果断的取舍，所以有些规律也有积累的必要，当然时间充分就没必要用了。

一：因spendless倒闭，但开新店（没限制说是什么类型的店）
二：因colson倒闭，开新店（没限制什么类型的店）

所以题干没说新店一定是同样类型的，B也没削弱到啊？
但是最后有一句“because it could not compete with Colson’s”，除非题目的assumption是discount store完全不能跟非折扣店竞争，但是这不太符合常识，新货店和折扣店的货和客源都是不同的嘛

作者: hjxsparrow 时间: 2010-10-14 12:19
做逻辑不要带着自己的常识做，而且你说的这个常识根本不成立啊，折扣店和非折扣店卖的商品和目标客户都不一样。
B就是一个类比。C是竞争力超强的非折扣店，导致再也没有新的非折扣店开张了。现在S也是一个竞争力超强的折扣店，也会导致没有新的折扣店开张
