Prep SC 一题请教

In Hungary, as in much of Eastern Europe, an overwhelming proportion of woman work, many of which are in middle management and light industry.

A.as in much of Eastern Europe, an overwhelming proportion of woman work, many of which are in

B. As with much of Eastern Europe, an overwhelming proportion of woman works, many in

C. As in much of Eastern Europe, an overwhelming proportion of woman work, many of them in

D. like much of Eastern Europe, an overwhelming proportion of woman works, and many are

E. like much of Eastern Europe, an overwhelming proportion of woman work, many are in

请问为什么C对？As不是比较句子，like用来比较短语吗？答案C的最后一部分many of them in middle management and light industry不是成了一个sentence fragment 吗?

不太理解这个语法现象，much是指代an overwhelming proportion of woman 吗？如果是，应该变成As (like) much in eastern europe 和in hungary保持平行

请指教

much 应该是指Eastern Europe的大部分地区。如果用like对比必须是 in Hungary, like in much of Eastern Europe,所以DE项排除。C项 many前面没有连词，所以本身many～～部分就不需要是句子，所以也就不是fagement了。应该有个专属名词叫这个结构，作用和插入语差不多。

plus, 不知道an overwhelming proportion of woman work 怎么理解，woman 是不是应为women？？？

谢谢指正，应该是打错了，women比较对。

也就是说，此题表明GMAT中as可以做短语的比较词？并不是非用like不可？

是不是like只可以修饰名词？这里是比较状语，不可以用like比较

更正一下，看来in Hungary, like in much of Eastern Europe也不对

like/as当比较讲时，like为介词，后面直接名词； as为连词，后面接一个句子

发现as后面接了名词，名词后必有助动词补出，否则错
