一道削弱题请大家来帮忙

    According to a recent cross-cultural study,married people in general have longer life expectancies than do people who divorce and do not remarry. This fact indicates that the stress associated with divorce adversely affects health.

Which of the following, if true, points to a weakness in the argument above?

(A)Overall life expectancies differ among countries,even among countries with similar cultures.

(B)People often show signs of stress when undergoing a divorce.

(C)Life expectancy varies with age-group, even among married people.

(D)Stress of many kinds has been shown to affect health adversely.

(E)Adults who have never married have shorter life expectancies than do married people of the same age.

我选的是D，因为我认为可以作为他因削弱,说明有其他原因来导致健康不良。

但答案是E。可我认为没结婚者和结婚者的比较不能说明离婚后未再婚者的情况。

还请各位帮帮忙，小弟在此先谢过了!

用排除法做下来,是E.--没有结婚的人没有受到离婚压力的影响,而寿命也短,所以weaken原题. D有strengthen 的作用.

是LSAT的题吧.建议以后先在本站内找找.

这种削弱的方法叫同果异因。
