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。
我的理解和解析的不怎么一样，我觉得是竞争关系的错误，有人预言5年内会有很多打折店倒闭因为竞争不过另一个打折店SpendLess discount department store 。但是这些空位一直会有后来的店来填满，不会空很久。因为另一家非折扣店Colson's的开业，这些补上来的店都陆续关门了，因为它们竞争不过这个Colson's（结论）。如果想削弱那么只能是要么削弱结论的内容即：能竞争得过。要么是削弱这个结论的本身即跟Colson's店的存在没有关系。根据选项只有b 削弱了后者，就是补上来的这些店的倒闭跟非折扣店Colson's没有关系，因为补上来的都是打折店，因为补上来之前倒闭的也都是打折店，那么这些后补上来的打折店的倒闭在逻辑关系上跟SpendLess关系更大。
