a. supermarkets will not also be selling children's clothes in the same manner b.personal service by sales personnel is not required for selling children's clothes successfully c.the same kind of computers will be used in inventory control for both clothes and toys at child's world d.a self-service plan cannot be employed without computerized inventory control e.sales clerks are the only employees of child's world who could be assigned tasks related to inventory control
答案是Ｂ，我选的是Ｃ 为什么呢？作者: alonegreen86 时间: 2011-12-7 20:22 作者: lorinlee 时间: 2011-12-7 20:31 我的理解是computerized inventory control 和 customer self-service是两种手段或方式，child world的假设应该是采用两种手段都能使卖衣服和卖玩具达到同样的目的，重点是目的而不是手段。作者: sdcar2010 时间: 2011-12-7 20:59
C) is too restrictive to be a necessary condition. Use your common sense: Is is NECESSARY for the store to use Dell ONLY???
Anyway, use the negation method would quickly find out the correct answer is B. Otherwise, there is no self-service!
