有时候去有关无关的概念很模糊，有时候清楚，有时候不明白，究竟如何判断有关无关呢？

大全testII
7. Recent evidence appears to contradict earlier findings that suggested that those who are physically fit cope better with stressful real-life events. Of a group of healthy women, those randomly assigned to a ten-week program of aerobic exercises performed no better in laboratory tests simulating stressful situations than did the subgroup assigned to a program without exercise.
Which of the following, if true, provides evidence for determining whether physical fitness makes one react better to stress?
(A) Superior reaction to laboratory stress situations was found to be more prevalent among women than among men.
(B) Healthy men, after training six months in weight lifting, encountered fewer potentially stressful situations in the subsequent six months.
(C) Subjects following a regimen during which they perfected their skills in a variety of relaxation techniques found that their lives seemed calmer after they began the regimen.
(D) College students with previous high levels of stressful life events showed a markedly reduced reaction to such events after training in aerobics for six months.（D）
(E) Subjects with a high level of self-esteem more often engaged in physical-fitness regimens than did a control group of subjects with average levels of self-esteem.
有一华籍美人说：
我刚才做这题也做错了，后来分析了一下，觉得是这样的：
原文问：下面哪个论据说明physical fitness可以使人们 perform better to stress
而原文的结论是认为：physically fit does not cope better with stress
所以可以说是weaken题，D以相反现象来说明fit确实能够reduce the act to stess，应该是最佳答案
A focus对象不对，原文是比较对stress反应程度，不是men or women
B focus对象不对，B选项是比较stress的多少，不是原文中的act to stress
C 原文没有提到stress与life calm的关系，所以不对
E原文没有提到self-esteem 与stress的关系，也不对
分析的有些罗嗦，可能大家早知道了，我选错了，所以详细的分析了一下
---怎样判断C-D有关无关？是不是文中没提到就是无关？但是答案D也没说到College students 怎样怎样啊，但是却是答案。这些应该怎么样的思路呢？
谢谢 |
