Because -> shows a cause-effect relationship.
in that -> You use in that to introduce an explanation of a statement you have just made.
differ in
前后并列
at不能省略
at是一定是加的，否则会有歧义：wrist可以理解成是在替代cartilage 也可以理解成是在替代 elbow，加了at则只能替代elbow；排除AE
C instead of 前后不平行 排除
B because of 加名词 being attached 错误
the correct idiomatic expression with 'differ' is 'differ in...', so a-b are out. (if you said 'differ because', you'd have to give the reason behind the genesis of the difference, not the nature of the difference itself.) that leaves c-d-e, which all contain the supposedly ambiguous pronoun.
选项A instead of at的 at 不能省；不能意思可以变成they are attached to the wrist.

选项A instead of at的at不能省；不能意思可以变成they are attached to the wrist.
because=in that，连词性质
instead of是介词，要么做定语修饰elbow，要么做状语修饰attach，怎么看都不对
还是rather than好啊，连词就没那么多毛病了，想跟谁并列跟谁并列，rather than前后直接两个状语并列，多好

ad之间错选了a

B，because of being attached，介词接名词，名词本身就是物体，不带主语，跟在介词后面没有表示先行词在being attached，应改成their being attached
C，in their attachment 和 being attached 不能平行，一个是动名词，一个是simple gerund
D，that前可以加介词，如：It is true in that all seated voted yes.；I am sorry for that.

选项A instead of at的at不能省；不能意思可以变成they are attached to the wrist.
because因为+造成两者不同的原因，in that在于+两者不同的具体方面
选项A instead of at的at不能省；不能意思可以变成they are attached to the wrist.
选项B Because of being表达不简洁
选项C in their attachment to和being attached at形式不对称;being attached at the wrist改变句子愿意
选项D 正确
选项E 歧义风险同A
in that在gmat里相当于because，并且in that（because）+句子比较好，because of 只能加名词
1.instead of/rather than 都可以，但前后是介词短语比较：at the elbow和at the wrist
如果缺at，可能造成歧义：a cartilage rod和 wrist比较
2.because因为+造成两者不同的原因，in that在于+两者不同的具体方面
because of being笨拙
3.C：their attachment to a cartilage rod at the elbow和 being attached at the wrist.形式不对称
且，改变了句意，being attached at the wrist少了 to a cartilage rod
A：instead of at的at不能省；不然意思可以变成they are attached to the wrist. 注意平行结构的识别，到底是哪部分与哪部分平行。
in that “因为，由于”，但过去正式，且慢慢被弃用。而从此题来看，in that仍旧能够使用，这点得改变自己的意识啊。
A: it's in the non-underlined part, about 1/2 line from the beginning of the sentence. the first word of the underlined part - the split between "because" and "in..." - is attached to "differ", although there's an intervening prepositional phrase (the one beginning with 'from').
唉你好呀
