GWD4-Q20 求助

Q40: GWD-4-20

Community activist:  If Morganville wants to keep its central shopping district healthy, it should prevent the opening of a huge SaveAll discount department store on the outskirts of Morganville.  Records from other small towns show that whenever SaveAll has opened a store outside the central shopping district of a small town, within five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district.

The answer to which of the following would be most useful for evaluating the community activist’s reasoning?

A.    Have community activists in other towns successfully campaigned against the opening of a SaveAll store on the outskirts of their towns?

B.    Do a large percentage of the residents of Morganville currently do almost all of their shopping at stores in Morganville?

C.    In towns with healthy central shopping districts, what proportion of the stores in those districts suffer bankruptcy during a typical five-year period?

D.    What proportion of the employees at the SaveAll store on the outskirts of Morganville will be drawn from Morganville?

这里答案是C，我选的是B，我在做的时候在ＣＢ之间纠结了一段时间，但是我觉得B更彻底啊，知道现在是否大部分的顾客在城内消费？如果现在已经有很多人本来就不是在城内消费的，那么即使开了那家店，对城内的影响应该也不会像题目说的这么严重了啊？C为何错？麻烦回的NN们帮我解答一下吧。谢谢谢谢

结论：prevent the opening of a huge SaveAll discount department store.

依据：records from other small towns- if opened, ¼+的stores suffer bankruptcy.

可看出文章内容有断层：1/4+的stores suffer bankruptcy是否就是more negative的？这个需要跟if SaveAll not open, the rate of bankruptcy来比较才能下结论。

因此此evaluation就是这个断层。
        

惯有思路：说某种东西存在的时候不好，答案要进行削弱就是说明没有这种东西更不好。

B无关了。shopping district的customer的多少 无法与 SaveAll对bankruptcy的影响 构成联系。
