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?
Many customers of Colson's are expected to do less shopping there than they did before the SpendLess store opened.
Increasingly, the stores that have opened in the central shopping district since Colson's opened have been discount stores.
At present, the central shopping district has as many stores operating in it as it ever had.
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.
Many stores in the central shopping district sell types of merchandise that are not available at either SpendLess or Colson's.
情景:虽然由于刚开业的SpendLess折扣店的竞争,Goreville中心地段的折扣店将在5年内关门,但这些地方不会空着。从非折扣店Colson开业起的5年内,每个关门的店铺处都有一个新店会开张。
推理:由于前提和结论讨论的事件相同,所以本题为类比推理。推理结构为:
前提:Colson倒闭店之后位置没空着。
结论:SpendLess倒闭店之后位置也不会空着。
选题方式:类比推理一共具有两个评估方向,要么提到Colson或SpendLess,要么给出与这两个案例相平行等价的案例C。
选项分析:
A选项:Colson的顾客现在在Colson购买的东西比SpendLess开业前更少了。本选项提及了两个类比对象,但是其和结论的相关性不大。
B选项:Correct. 在Colson开业之后开的店中,开起来的店都是折扣店。本选项指出了类比对象的区别,即,以前能不空着是因为可以开折扣店,现在开折扣店已经没用了。属于CQ1:相似性问题。
C选项:目前,商业中心的店铺数量跟以前一样多。本选项给出了类比对象的相似点,只能加强推理。
D选项:接下来的5年,Goreville的人口增长率将会比之前的十几年增加。如果人口增加,那么商铺更加不会空着了。
E选项:很多中心区商店的商品在SpendLes或Colson店都买不到。本选项没有提及类比对象的不同点。
居然做对了....有种赌一把赌对了的感觉。还是再仔细看看题。
这题的顺序需要仔细看。
结论在第一句中,前提在第二句。要注意观察第一句中的within five years和are expected to表示这是一个预期,还有第二句中的in five years和has opened表示这是已经发生的事。
作为类比推理,两者都提到该店开了导致购物街区的其他同类商店关门,前提中因为Colson关掉的店又开了新的店,所以结论是因为Spendless关掉的店也会再开。
要找类比对象的不同点,或者举一个反例减低其类比关系。
B选项告诉我们“在Colson开业之后开的店中,开起来的店都是折扣店”,而这恰好是因为Spendless关掉的店,如果再开非折扣店,可能要和Colson对抗。
因此,一时间难以很快再开新店。
可以 很强势
解释的非常清晰。最后B削弱是不是可以更具体理解为,无论开折扣店还是非折扣店,都会和C S商店产生竞争,所以不可行
