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?
it should prevent的依据是：Records from other small towns ，是一种策略达目的性，那评价的方向即此策略可达目的吗？这样想答案肯定要跟bankruptcies 有关。B其实是无关选项了：因为还存在其他更多的因素来评价消费群，与本题推论无关。作者: giflier 时间: 2010-10-4 06:46
结论：prevent the opening of a huge SaveAll discount department store
依据：records from other small towns- if opened, ?+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。
