问题 单项选择题

张小珍:在我国,90%的人所认识的人中都有失业者,这真是个令人震惊的事实。王大为:我不认为您所说的现象有令人震惊之处。其实,就5%这样可接受的失业率来讲,每20个人中就有1个人失业。在这种情况下,如果一个人所认识的人超过50个,那么,其中就很可能有1个或更多的失业者。 以下哪项最可能是王大为的论断所假设的( )

A.失业率很少超过社会能接受的限度

B.张小珍所引述的统计数据是准确的

C.失业通常并不集中在社会联系闭塞的区域

D.认识失业者的人通常超过总人口的90%

答案

参考答案:C

解析: 选项B并不是王大为的论断必须假设的。因为即使张小珍所引述的统计数据不准确,王大为的论断仍然可以成立。A项和D项也不是王大为的论断需要假设的。选项C是王大为的论断需要假设的,否则,如果事实上失业通常集中在社会联系闭塞的区域,那么,一个人所认识的人的数量就可能大大降低,以上所分析的王大为的第三个断定就不能成立,因而基于之上的论证也就难以成立。
