问题 单项选择题

据对一批企业的调查显示,这些企业总经理的平均年龄是57岁,而在20年前,同样的这些企业的总经理的平均年龄大约是49岁。这说明,目前企业中总经理的年龄呈老化趋势。 以下哪项,对题干的论证提出的质疑最为有力( )

A.题干中没有说明,20年前这些企业关于总经理人选是否有年龄限制

B.题干中没有说明,这些总经理任职的平均年数

C.题干中的信息,仅仅基于有20年以上历史的企业

D.20年前这些企业的总经理的平均年龄,仅是个近似数字

答案

参考答案:C

解析: 正如C项所指出的,题干的论据,仅仅基于有20年以上历史的老企业。而题干的结论,却是对包括新老企业在内的目前各种企业的一般性评价。如果上述这样的老企业在目前的企业中占的比例不大,则题干结论的可信度就会大为降低。因此,C项是对题干的有力质疑。其余各项均不能构成对题干的质疑。
