Answer: B 我选C，LZM解释说C里面的of which 用要逗号隔开，但which前面跟介词在GMAT中是接受的。
Research during the past several decades on the nature of language and the processes (that produce and make it understandable has revealed great complexity instead of underlying simplicity).
A)......
B) by which it is produced and understood has revealed not underlying simplicity but great complexity
Answer: A, 我选了B
我的意思是既然A 选项是: processes produce and make the language understandable
那么就可以改写称为: the language is produced and made understandable by the processes
这点你同意哇？
第一题：
要用逗号，也只能这样：
a child born into a family， the members of which hv allergies， will probably develop an allergy
而这样显然没有B简洁。
第二题：
你的选项的逻辑混乱。
Research（主语） during the past several decades on the nature of language and the processes (that produce and make it understandable [谓语has revealed] great complexity instead of underlying simplicity).
