问题 单项选择题

在美国,今年以来在电视卫星发射和操作中事故不断,这使得不少保险公司不得不面临巨额赔偿,这不可避免地导致了电视卫星的保险金的猛涨,使得发射和操作电视卫星的费用变得更为昂贵。为了应付昂贵的成本,必须进一步开发电视卫星更多的尖端功能来提高电视卫星的售价。
以下哪项如果为真,和题干的断定一起,最能支持这样一个结论,即电视卫星的成本将继续上涨

A.承担电视卫星保险业风险的只有为数不多的几家大公司,这使得保险金必定很高。
B.美国电视卫星业面临的问题,在西方发达国家带有普遍性。
C.电视卫星目前具备的功能已能满足需要,用户并没有对此提出新的要求。
D.卫星的故障大都发生在进入轨道以后,对这类故障的分析及排除变得十分困难。
E.电视卫星具备的尖端功能越多,越容易出问题。

答案

参考答案:E

解析: 要支持的结论是“电视卫星的成本将继续上涨”。题干的已有前提是“事故多,使得保险金高,从而使电视卫星的费用昂贵”。要得到题干的结论,必须强化已有的前提,即“事故更多”。E说明的就是这一点。
