Q20:

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?

1. Have community activists in other towns successfully campaigned against the opening of a SaveAll store on the outskirts of their towns?
2. Do a large percentage of the residents of Morganville currently do almost all of their shopping at stores in Morganville?
3. In towns with healthy central shopping districts, what proportion of the stores in those districts suffer bankruptcy during a typical five-year period?

4. What proportion of the employees at the SaveAll store on the outskirts of Morganville will be drawn from Morganville?
5. Do newly opened SaveAll stores ever lose money during their first five years of operation?

答：C

请教一下，Evaluate这种题型要怎么判断？

just like an assumption. Given the question, the answer is yes and the conclusion above is yes, but the answer is no and the conclusion above is also no.

评价题是加强/削弱的演绎题形，回答肯定变成加强，否定变削弱。

这道题看文章是causal-explanation结构；Community activist的reasoning:

other small towns show that whenever SaveAll has opened outside the central shopping district－within five years the town has experienced the bankruptcies in the shopping district－>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

所以通过C的问题看是街区的哪一部分商店倒闭。主要是看是不是huge SaveAll discount department store 引起的。回答的是否就可以影响原文的结论。

楼上的解释欠妥。

within five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district.==》答案what proportion of the stores in those districts suffer bankruptcy during a typical five-year period；more than a quarter 与what proportion形成比较

within five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district. 怎么答案与上句是一样的呀，原文已经回答了what proportion of the stores in those districts suffer bankruptcy during a typical five-year period这个问题了嘛。这道题出得挺奇怪得。以前坐evaluate题得时候÷ 好像没有这种现象呀。

这T 还是不是很明白

感觉好象是C 的选择读起来不是很明白

应该是five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district 和 In towns with healthy central shopping districts, what proportion of the stores in those districts suffer bankruptcy during a typical five-year period? 的联系吧

感觉是象LEEON 说的那样子 但默默忽忽的感觉

哪个NN 解释一下 谢谢先

这题说 如果M要保持中心商业区的健康发展，就不应该在城市的边缘地带建立便利打折店。 因为，一个小镇的记录表明，当这种Saveall便利店在边区开小店的时候， 五年内这个镇的中心商业区有四分之一的破产。

问需要那个条件才能判断作者推理对不对， 选c， 就是问在正常的五年内一般都多少破产啊。

如果正常年份，破产比四分之一还多，那不是就不能证明便利店的危害了。 如果正常破产是个什么一百分之一，那这种便利店的确导致破产增多， 危害大，就可以证明作者的论点了。

所以知道， 正常年份的破产率很重要。

但是LEEON 的那种理解是怎么引起的呢
