50. Although computers can enhance people’s ability to communicate, computer games are a cause of underdeveloped communication skills in children.After-school hours spent playing computer gamesare hours not spent talking with people. Therefore,children who spend all their spare time playing these games have less experience in interpersonal communication than other children have.[c1]
The argument depends on which of the following assumptions?
首先给出我的理解，（求批评~）：这道题的充分条件就是 spend all their spare time playing these games~ 必要条件就是 have less experience in interpersonal communication than other children have
接下来，就有问题了：“什么叫排除？” 我的理解：是那个“not”。而排除的意思就是：假设没有充分条件，即 Children who do not spend all of their after school hours playing computer games spend

只要spend all their spare time playing these games-->have less experience in interpersonal communication 除非spend all their spare time playing these games-->否则不会have less experience in interpersonal communication 排除只要不spend all their spare time playing these games can have at least some of that time talking with other people
