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 form Morganville? E. Do newly opened SaveAll stores ever lose money during their first five years of operation? Answer:C 题目中已经有讲到 bankruptcies of more than a quarter of the stores in the shopping district 所以已经确定有stores 被影响 答案怎麽又回来说要确定到底有多少商店被影响呢 搞不清楚这题的逻辑 请各位牛人帮忙解释一下 谢谢 --
