[求助]OG11-52~为什么我的OG上的52题跟坛子里搜到的不一样？

52. Although computers can enhance people's ability to communicate, computer games are a cause of underdeveloped communication skill in children.After-school hours spent playing computer games are hours not spent talking with people. Therefore, children who spend all their spare time playing these games have less experience in interpersonal ommunication than other children have.

the argument depends on which of the following assumption?

A. Passive active such as watching tv and listening to music do not hinder the development of communication skill in children.

B. Most children have other opportunities, in addition to after-school hours, in which they can choose whether to play computer games or to interact with other people.

C. Children who do not spend all their fter school hours playing computer games spend at least some of that time talking with other people.

D. Formal instruction contributes little or nothing to children's acquistion of communication skills.

E. The mental skill developed through playing computer games do not contribute significantly to children's intellectual development.

ANSWER: C

不是很明白什么意思 ？我选的答案是B

 我搜了坛子里所有带OG 跟52的帖子，都没有这个题目， 这个是OG11上的52T,  坛子里的52T 都是另外一个关于跑步机的，难道这个版本太新了么 ？？

疑惑中····

没有人回复么？ 顶一下···

把c取非，如果不玩电脑的孩子没有把时间用在和人沟通上，那么玩电脑的孩子的沟通能力就不该比那些孩子差。

b是无关信息。

从问题中depends on可以看出本题是必要型假设，即：答案应该是结论的必要条件，也就是结论成立的话，答案必成立

本题的前提是：

1。电脑游戏导致孩子的沟通能力变低；

2。放学后花在电脑上的时间就是没有花在与人交流的时间

结论是：相比其他孩子（用a表示），那些把课余时间全部花在电脑游戏上的孩子(用b表示)与人之间的交流经验少。

那么结论中一定可以推出来其他孩子(a)一定有把一部分时间花在与人之间进行交流上，不然的话就不可能比那些孩子（b）的经验多。（为必要条件）
