patterns of stress that A are more likely than those(patterns of stress) that B are , 然后把are 倒装

A is more likely to do than B is

B：as far as "what"---
this construction is idiomatically ok: what + SUBJ + VERB is a perfectly good way to generalize the object of that particular verb.
for instance, what you eat means, basically, "the things that you eat“.

平行结构：pattern of stress that boy experienced are less likely to ....
than are those that boy experienced

比较题真的是做一题错一题，明明知道要注意前后的句式，还是会错。。。

A were more likely to do sth than B were，主句是SVO结构，此时被比较部分一定要带上谓语动词be，
A were more likely to do sth than B，会让人误解为A were more likely to do sth than do B

比较前后成分要相同，E没有定语，因此两个patterns不可比

看清楚比较对象，究竟是主语在比较还是宾语在比较。

than前一句是主谓宾完整的句子，than后也需要补充出完整的动词，否则容易产生歧义——比较宾语还是比较主语？

A were more likely to do sth than B were，主句是SVO结构，此时被比较部分一定要带上谓语动词be，
A were more likely to do sth than B，会让人误解为A were more likely to do sth than do B
【总结】A is more likely to do than B is
选项A， 代词those的指代对象是句前出现的patterns of stress，that引导的定语从句是修饰代词those的。补出的be动词are表明了比较的是两种情况，而不是“男孩的经验”。

注意句子到底想比较的是什么内容。

这里的are不能省略，引起歧义。比如E，可以表达会更有可能引起沮丧比引起男孩的压力模式。

第三次终于做对了，真正的会了，到底是than前后谁跟谁比，应该补be动词还是实意动词，用that还是those，倒装。

A is more likely to do than B is

惊人的一幕又发生了，这道题第二次做错了。。。

A is more likely to do X than b is. 注意补足成分，语义这样比较的话最后一个is 不能省略。

A，patterns of stress that girls experience是个定语从句，that在从句里充当宾语
B，what boys experience是个名词，从比较结构上是可以的，A is more exciting than B（比较省略的原则在于是否会引起歧义，不一定要带上谓语动词或助动词）
但B的逻辑意思不对，what boys experience可以是男孩经历的一切，不特指patterns of stress，而原文要比较的事patterns of stress that girls experience are……than patterns of stress that boys experience

A. the patterns of stress that girls experience are ... than are those that boys experience == the patterns of stress that boys experience are

D选项do应该指代action verbs，不能代替be动词are。 B选项语法正确，但是太概括了，boy经历了很多不能表明就是stress..
原文的more likely比较的是概率的大小，than后面只能加are；如果原文改成are likely to result more in depression，那么than后面可以加do/would/can等。
