107. 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 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 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.

解释部分的意思：题干中的arguement的逻辑是建立在两个case相似，可进行比较的基础上，只要能证明两个case不可比，则可削弱此逻辑推理。选项B指出在colson的案例中nondiscount的店导致了周围的店关闭后被discount的店取代，而在spendless的案例中，这个需求（对折扣店的需求）不再存在，因此两案例不可比。
这个是解释部分的意思，我自己的理解是：
colson案例中，nondisctount店关门，discount店取而代之；而在spendless案例中，本来就是discount店，不一定有比discount更吸引人的业态能够在那里成功，所以未必旧店关门后会比新店取代。
希望帮到你。

我的理解是：第一句话里面很快有新开的店把空地填了，是结论。怎么weaken结论呢？如果能用例子证明了既不会再有discount store开，也不会有non-discount store开，就可以。
那现在分析第二句提供的fact情景：第一种情况，如果non-discount store因为C的竞争关了不久又会有non-discount store开的话，证明当地人有一种不怕死的精神；同样的逻辑成立的话，用到结论里面，当地人对S的竞争也是不怕死，还会继续有discount store新开，把空地填了，是strengthening；
第二种情况（也就是B答案)，如果non-discount store因为C的竞争关了不久就不会再有non-discount store开的话，而以后都是开的劈开竞争的discount store的话，证明当地人缺乏一种不怕死的精神，选择避开比自己更强大的竞争对手和市场；那就带来，结论里面的情景下，当S开了后，由于S的竞争一些discount store关门后，当地人也会承认失败避开原有discount store的市场，不会再开discount store；（由于前提里面C的竞争，也不会再开non-discount store），所以就没有人来开店了，空地就一直空着，是weakening。

甭看他的解释，考场上用不着，一分半钟一般是想不通逻辑关系的，只看是否相关
A 客户被期待。。。主观，错
B，说开店的问题，地方范围也对，留着
C,店的数量与过去的数量对比，原文说新店会开张因为没竞争，无关
D,人的数量问题，自己只用通过联想才能与原文连上，主观，错
E，卖的东西的是什么，原文没有说，错


只剩下B，B为什么对 不知道，其他四个一定错。模模糊糊就可以在短时间内做完，且不用怎么想

解释的很好。
是类比削弱题，主要是找类比过程中的不同之处，然后削弱。

找到结论是关键：because it cannot compete with colson's , a new store has opened at the location of every store in the shopping district that closed
去weaken这个conclusion的方法，就是其他原因caused the new store closed 那么b选项就可以选出，b选项是说开的都是discount store，那么导致那些new discount stores closed 的原因不是cannot compete with colson's，而是因为spendless

黑瞳之人

题目给的需要被削弱的类比推理的逻辑是：一些店面重新出现在了那些竞争不过C店（非折扣店）的店铺的位置上（这些店铺已经关门了）；所以一些店铺也会重新出现在那些竞争不过S店的店铺位置上。而非折扣店是竞争不过折扣店的。所以削弱选B的原因是：那些后来在C附近开业的店是折扣店，因为他们觉得自己能竞争过C；但是题目又说了折扣店是竞争不过spentless店的，所以不太可能开在S附近。属于给出了类比对象的区别，因为之前一直是折扣店和折扣店比，非折扣店和非折扣店比。 个人理解，欢迎指正。

不二过

说类比的各位NN，我多问一句，Spenniless和Colson本来就不是一类店，性质上就不同了，还有啥可类比的。。。

哇这个解释真的非常清楚了！ 感谢！

我的理解是 举C的例子来进行类比，但说明这是无关类比就可以削弱
C（nondiscount）开张 ==》 周围的店竞争不过倒闭==》还是有新店开张

想推出，即使这家店很厉害，别的店都倒闭了，还是会有店不怕死开张
那得说明，C周围新开得店和C是一样得才行，说明同类店哪怕竞争不过，也会不怕死开张，有小强精神
G（discount)  开张 ==》 S （discount ) 会倒闭==》新店开张

如果不能保证两个竞争的店是同类得，那就还有其它原因。因为没有办法比较 两个不一样得店，只有一样得店才能进行比较。

天哪，太晕了。。遇到这种题我直接死掉好了
