请教大全-3-1，谢谢！

Child’s World, a chain of toy stores, has relied on a “supermarket concept” of computerized inventory control and customer self-service to eliminate the category of sales clerks from its force of employees. It now plans to employ the same concept in selling children’s clothes.

The plan of Child’s World assumes that

(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（B）

(E) sales clerks are the only employees of Child’s World who could be assigned tasks related to inventory control

请问B是怎么得到的呢？

天之角，请问successfully反映了原文的哪个信息点呢？

祝杀G成功啊！记得要来报喜啊~~~~~~~~`

这个我也没找到，我觉得好像就是上个计划成功了才会移植到selling children's clothes上吧。

谢谢你，借你吉言了，希望不要考得可差就好，呵呵。
