Medical personnel who served in heavy combat in a
recent war-even those who escaped physical injury-now
have lower incomes and higher divorce rates, and score
lower on psychological profiles measuring general
happiness, than medical personnel who served in less
stressful settings during that war. This evidence
demonstrates that exposure to heavy-combat situations
produces serious adverse effects, even among those who
suffered no physical harm.
Which of the following, if true, most strengthens the
conclusion drawn above?
The medical personnel who served in heavy combat had
completed significantly less schooling prior to military
service than had other medical personnel.
The medical personnel who served in heavy combat
tended to be younger at the time of their entry into
military service than were other medical personnel.
Parents of medical personnel who served in heavy
combat show no significant difference in incomes,divorce
rates,or general happiness from parents of other medical
personnel.
Income levels, divorce rates, and levels of general
happiness are the same for the medical personnel who
served in heavy combat as they are for construction
workers.
Medical personnel who served in heavy combat in an
earlier war show no significant difference in incomes,
divorce rates, or general happiness from other medical
personnel who served in that war.

答案：(C)
问题：下面哪一个，if true，最支持上面的结论？
读题：服务于重大战役的医疗人员 —— 甚至那些没有受伤的医疗人员比那些不那么有
压力的医疗人员,现在有较低的收入，较高的离婚率，并且在测量一般快乐的心理
侧面图得分低。这个证据表明对重大战争情况的暴露产生了严重的不利影响，
甚至是对那些没有受到物理伤害的人。
分析：论据是一个事实，服务于重大战役的医疗人员比不那么有压力的医疗人员有较低
收入、离婚率高等情况。
结论是对重大战争情况的暴露产生了严重的不利影响(这也是原文中比较涉及的唯
一区别点) 结论对事实做了一种解释。
此类支持形式为：
1、 没有其他的原因来说明为什么服务于重大战役的医疗人员比不那么有压力的医疗人员
有较差的状况。
2、 直接说那些较差的状况和对重大战争情况暴露两者之间的关系
c. 服务于重大战役的医疗人员的父母与其他医疗人员的父母在收入、离婚率和快乐方面是
没有显著区别的
（利用了assumption的形式，遗传不起作用，最好地支持确实是环境起了作用）
e. 在上一次战争中，服务于重大战役的医疗人员与其他医疗人员没有显著不同
（上一次没有这样的情况，可以作为反对，注意答案不需要充分性）
