A study on couples' retirement transitions found that women who took new jobs after retiring from their 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
这个句子中(C) more so than those who retired 是什么成分啊

ayoyoyo

这里so前面既然有more，指代的只能是前面的形容词high；从意思上也是如此。
这一个片段就是一个形容词片段，在句子中很常见，类似于"He likes big one, bigger than xx."这种.
