Which of the following most logically completes the argument below?
Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville. The downtown shopping district has lost business at this rate before and has always completely rebounded. Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because __________.
A. the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores, on whose ability to draw shoppers many of the other downtown stores depend
B. the bus line that has long connected the downtown area of Morganville with East Morganville has a tradition of carrying shoppers who reside in East Morganville into downtown Morganville to shop
C. when the downtown shopping district has rebounded before, the business premises of a failed business were typically taken over by a business of the same kind as had been there before
D. SaveMart's business plan for the East Morganville store is based on earning low profits, if any, during the first five years of the store's existence
E. it is conceivable that the downtown shopping district could shrink substantially without collapsing altogether为什么不选择C呢？
以前failed的企业都被同类企业接管了，现在没有企业接管了，所以就不能rebound了，是因为接不接管和SM公司的竞争没有关系么？

这个题吧，我理解和OG13 CR107内容类似只处，但推理的过程和结论完全都不一样OG13 CR107 类比：非打折的店 ...

。。。。。。楼上的解释，选项C翻译都错了，汗。。。。。。
这里C的意思是：当以前反弹的时候，这些business前提是失败的business要被同类型的business所顶替。
这个呢，也不能说不对。只是A更好更明确更直接，C呢，属于逻辑中很有困惑性的一类选项，即带入主观臆断型。
怎么主观？就是原题没有讲这些倒闭的商店是不是和savemart同类型的，没有讲，就不要瞎推测了。而C呢，想当然地认为这些倒闭的商店就是和savemart不同类型的。
所以比较下来，A更直接。
逻辑题和SC题一样，也是比出来的最优的。在考场上，其实也来不及想到上面的反驳理由。只是觉得A更好。

也做错了，说说我的理解

Downtown有AAA, BBB, CCC商店,East出现竞争对手后Downtown的商店会减少20%,以前也减少过20%但后来恢复了。

A 正确选项
这回不会恢复了，因为:这回竞争对手消灭的是AAA(boss)商店，没了AAA(boss)其他依附的商店也就会相应减少。Point:消灭的是AAA(boss)。（以前减少的是BBB(manager) /CCC(nobody)商店，因为AAA(boss)商店还在，减少的20%可以在恢复。）

C 迷惑选项
这回不会恢复了，因为:以前能恢复是由于AAA被aaa消灭了。Points:是被aaa消灭的。（如果这回AAA被aaaaaa消灭了，就不会恢复）。这个Logic上无法得到，所以错。
能不能恢复的关键在于谁被消灭，而不是被谁消灭。我觉得这题的关键在于对20% of the stores的理解。

以前failed的企业都被同类企业接管了，现在没有企业接管了，所以就不能rebound了，是因为接不接管和SM公司的竞争没有关系么？
->不是failed的企业被同类接管，而是出现了同类企业，致使原来的企业failed。前后顺序不一样。

这个题吧，我理解和OG13 CR107内容类似只处，但推理的过程和结论完全都不一样
OG13 CR107 类比：非打折的店竞争不过C，但不久新的非打折店会开张——〉打折店竞争不过S，但不久新的打折店也会开张
答案是：这种类比不成立，在C（非打折店倒闭的地方）新开张的打折店（而不非打折店）

这个题推理过程是：
Fact1 由于竞争不过打折店S， M中心商业区20%的商店在5年内都会倒闭，
Fact2 在中心商业区（购物中心）商业下滑到20%前总会完全反弹
但是，坚信（即将经历这种下滑到再次反弹）的信心是错的，因为~~~~
conclusion是 Confidence is ill founded ，再简化一下，就是在中心商业区的store 开业不会 rebound
题目分析，找一个（在中心商业区的store 开业不会 rebound 的）理由
选项分析：
A 和S竞争破产的商店是中心区的主力店。显然主力店都竞争不过倒闭了，怎么会有新店能竞争过，还反弹？
B 公交线路，和反弹无关
C 提到反弹了，这个干扰较强；
但仔细分析，说在中心区商业反弹前，倒闭生意的营业场所还会被和它倒闭前一样的业务接替
1 选项说的是business 不是shop 、store论述对象错，选项故意把范围放大了
其实原文说的business 仅仅是 shop 、store
2 即使 business =shop，那说反弹前，新商店会接替倒闭的商店，不正说明有可能rebound了吗，可这刚好和结论相反
D S的薄利多销的商业计划，和反弹无关
E 可以想象中心商业区会大量萎缩不会完全崩溃；这个和原文的结论类似，但题目是让找个理由，不是让重复一下结论
