[size=14.007px](C) boys' experience would
[size=14.007px](D) boys' stress patterns do
[size=14.007px](E) stress patterns of boys

[size=14.007px]

[size=14.007px]正确答案为A， 做题时在A和D中纠结，后来想are those that boys experience为倒装与the patterns of stress that girls experience are 不平行，于是乎选了D。
[size=14.007px]求各位指点迷津，倒装和正常语序可以平行吗？为啥选A呢？

gmatclub 上的有关这题的答案：


Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than the patterns of stress that boys experience are likely to result in.

A says:

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than those (patterns of stress) that boys experience are likely to result in.

With D, the sentence would be:

Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress that girls experience are more likely to result in depression than boys’ stress patterns do.

So, if you compare this with the intended sentence, at the very least, do is trying to substitute for are likely to result in. Notice that are is an auxiliary verb.

I am pretty sure (unless someone can cite an example to the contrary) that do (and similarly did/does ) cannot substitute for auxiliary verbs. do/did/does can only substitute for main verbs. So, following would be correct:

He runs faster than his classmates do.
- do correctly substitutes for main verb runs

Following would be incorrect:

Jack is more successful than his brothers do.
- do cannot substitute for auxiliary verb is

The correct sentence would be:

Jack is more successful than his brothers are

个人觉得不用抠太细，这里只是补出了系动词而已，即 A are more..in X than are B，是A和B比较。

如果不补出are，句子结构会变成 A are more..in X than B，变成了X和B比较。
