prep 114

A study on couples' retirement transitions found that women who took new jobs after retiring from heir primary careers reported high marital satisfaction, more than when retiring completely.

(A) more than when retiring

(B) more than if they were to retire

(C) more so than those who retired

(D) which was more so than those retiring

(E) which was more than if they had retired

B为什么不对呢？

B里面最大的错误是more than修饰的是satifaction，所以是satifaction与if从句的对比，比较对象不平行。

study比较的是两个群体，而不可能是某个群体的一个状态和对该群体的一个假象态的对比(那样就不是严谨的调查研究了)。
