问题 单项选择题

陈先生:北欧人具有一种特别明显的乐观精神。这种精神体现为日常生活态度,也体现为理解自然、社会和人生的哲学理念。北欧人的人均寿命历来是最高的,这正是导致他们具备乐观精神的重要原因。
贾女士:你的说法难以成立。因为你的理解最多只能说明,北欧的老年人为何具备乐观精神。
以下哪一项最可能是贾女士的反驳所假设的

A.北欧的中青年人并不知道北欧人的人均寿命历来是最高的。
B.只有已经长寿的人,才具备产生上述乐观精神的条件。
C.北欧国家都有完善的保护老年人利益的社会福利制度。
D.成熟的理解自然、社会和人生的哲学理念,只有老年人才可能具有。

答案

参考答案:B

解析: 陈:人均寿命高→乐观精神。
贾:老年人→乐观精神。
贾女士说明了只是老年人因为长寿才乐观,削弱了题干对北欧人的整体情况所做的判断。
