A) 缺少指代women的代词，致使more than的比较对象不对等，satisfaction与when retiring对比。

(B) they指代前面的women，表达意思错误，因为if they were to retire表达了同一群妇女不同情况下的satisfaction对比，改变了原句意思，原句要表达的是不同妇女不同情况下的satisfaction对比；more than前后不平行。

(C) 正确，those指代women，who took和who retired平行。

(D) which与so都指代satisfaction，重复；which就近修饰satisfaction不符合语义

(E) they指代前面的women，表达意思错误，与A选项相同；没有特殊的时间标志说明需要用过去完成时had retired。

“more so than” is an idiom

It is used in making a "more than" type of comparison where you also want to refer to a previously stated verb/action (that's where the "so" comes in). In this case, the "so" refers to "reported high marital satisfaction."

Notice here that you are comparing two groups of women: those who take new jobs, and those who retire completely. When making a comparison, you have to make sure you explicitly mention both groups.

B, C, and D don't do this. (In fact, B and D change the original meaning of the sentence to make the second part of the comparison a hypothetical - but the original meaning is that the ones who take new jobs are being compared to those who don't.)

Also remember that, for comparisons, the two things/groups / whatever compared should be parallel. "women who took" and "those who retired" are parallel. The other options aren't.

which，先行词为satisfaction，这是不合理的，排除
A，比较对象不一致，且doing缺少逻辑主语
B，they是完全指代，不合理
C correct

C中so指代前文的reported high marital satisfaction

前一种women比后一种women的satisfaction更高，后面需要出现人

无脑选B,虽然犹豫了一下！

A study on couples' retirement transitions found that women who took new jobs after retiring from their primary careers reported high marital satisfaction, more [so#reported high marital satisfaction#] than [those#women#] who retired completely.

In this case, the "so" refers to "reported high marital satisfaction."

RULE: if it's not a specific NOUN that can be replaced by a PRONOUN (usually "it"), then use the all-purpose replacement "...so".

more than的题还是要重点关注平行，前句是 woman who took...after.... 我们期待的平行的比较是... who....

先确认比较对象——两类women
(A) 缺少指代women的代词，致使more than的比较对象不对等
(B) they指代前面的women，表达意思错误，因为if they were to retire表达了同一群妇女不同情况下
的satisfaction对比，改变了原句意思，原句要表达的是不同妇女不同情况下的satisfaction对比
(C) 正确，those指代women，who took和who retired平行。it/they/that/those只能指代名词，不能指代句子，so可以reported high marital satisfaction
(D) which不能指代一件事或者一句话
(E) they指代错误同B；没有特殊的时间标志说明需要用过去完成时had retired。

more so, so refers to report... if D, which refers to satisfaction, 不可与后面those retiring的women主语对比

1、比较的对象：由语义判断（retiring），是xxx的女人比yyy的女人report更多满意，所以比较的对象是——women
2、这样只剩下CorD，C的语法和整句是契合的

so指代reported high marital satisfaction
省略式的说法

不能用they也不能省略，两种情况都表示被比较的对象是 women who took new jobs after retiring
more作为同位语，which指代high marital satisfaction，这里应该是women were more，不是这些满意度more

so可以代替high marital satisfaction

so指代reported high marital satisfaction
省略式的说法

CE错误：
首先比较的对象是不同的女性（不完全退休和完全退休这两种），所以DE的定语从句针对的是satisfaction，不对。
A, more than 前后不对称
B，they 代指women? 那个这个代指就会同时囊括前句women以及其定语从句
those who retired对应前句的women who took new jobs
more so than ，so代指前句，more than是连接词（？）

这题也可以通过平行解决

women是复数

more so than those who retired=reported high marital satisfaction more than those who retired
严格讲起来，由于比较句是SVO结构，women reported satisfaction，后面跟的比较对象是要补出谓语动词的，这里按句意来理解，women reported more satisfaction than those women reported satisfaction，而不是women reported more satisfaction than reported those women 。
