楼主你好啊~~可以教下我这个问题吗？
From studies of the bony house of the brain, which is the cranium, located in the back of the skull, come what scientists know about dinosaur brains.





















(A) From studies of the bony house of the brain, which is the cranium, located in the back of the skull, come what scientists know about dinosaur brains.










(B) The knowledge that scientists know about dinosaur brains comes from studies of the bony house of the brain, located in the back of the skull, that is, the cranium.










(C) The knowledge of dinosaur brains that scientists have come from studies of the bony house of the brain, which is located in the back of the skull and is called the cranium.










(D) What scientists know about dinosaur brains comes from studies of the cranium, the bony house of the brain located in the back of the skull.










(E) Located in the back of the skull is the cranium, the bony house of the brain, and it is from studies of this that scientists know what they know about dinosaur brains.

这里的A选项我一直就不太懂，located说是有修饰cranium和brain的歧义，但是别人的解释的是说located..做定语。这里的located。。。为什么是做定语呢？我之前看到说过去分词做定语是有2种情况，1.主句是完成时，那么分词失去了最、做状语的功能 2.主句的时态为被动的时候。    切割线。。。。。。。。。

好就算这里的located是做定语，which.....cranium。这个句子不是可以相当于插入句吗？located。。不就跳过了这个句子修饰前面的brain的吗？这个时候A选项哪里来的歧义啊？
还有B选项的located说修饰对象不清楚~~具体指什么啊~~~~~~~~


跪求大神教我啊·~~~我一直就很迷糊这个问题啊~~~~

反对楼上所说, A     And not is not
a correct idiom; as should be followed by a clause


 

B      Although like
can grammatically be followed by a noun phrase such as nuclear reactors,
here the basis of comparison is unclear, and the usage is incorrect


 

C    Correct. Rather than is a correct
idiom for comparison in this sentence; as is followed by a clause with a
subject, nuclear reactors, and a verb, do; the comparison is
clear and complete.


 

D     Illogical and
awkward construction attempts to make merges the second verb of the
restrictive clause parallel to powers and does not split-, punctuation
makes clear this separate action cannot be the case; as is done is
awkward and wordy


 

E      Illogical and
awkward construction incorrectly makes merges the second verb of the
restrictive clause and a separate action parallel to powers; comparison
is awkwardly drawn; switch from nuclear to atomic is unexplained and
unsupported
