72.   Community activist: If Morganville wants to keep its
central shopping district healthy, it should prevent the
opening of a huge SaveAII discount department store
on the outskirts of Morganville. Records from other
small towns show that whenever SaveAII 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 SaveAII 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 SaveAII
store on the outskirts of Morganville will be
drawn from Morganville?
(E)    Do newly opened SaveAII stores ever lose
money during their first five years of operation?

大家是如何排除B选项的？解释The conclusion would be supported just as well—or as poorh/—if this question were answered
with a yes as with a no.
我没太明白。。。谢谢~~

可以理解成这样，就是不论是否现在有大量的居民在城中心消费，都与activist的结论没有直接关系

B无关么  消费的人多少不能直接决定一个商店的倒闭与否

当然 消费者多少是可以影响,但是不是最直接最为切中要害的描述

比如:99%的人都买, 但都只买个棒棒糖, 其他1%是去买飞机的 那怎么比哪>?

呵呵 找直接切中要害的选~~

仔细理解..逻辑的精华就在这里
