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.

大案是D

但是B中located in the back of the skull 修饰的歧异在那里呢？

E中解释说it ,this 指代不清，可是我觉得最大的问题还是and it is 没有并列，同意吗？

可是我为什么看不出来located有修饰knowledge的嫌疑，晕晕啊

我觉得B里面的that is没有错，做插入语嘛...prep说它指代不清...

关于that is的用法在OG里就有一个：OG10-186的解释。

Members of the jury must be the logical subject of both options, and both must be expressed in parallel form, that is, as infinitive clauses.

B中当我们不知道
                located in the back of the skull是修饰house还是brain.

E里面确实有不平行的错误。know what they know很变态很awkward的表达...

再看了一下，正确选项E里面也是过去分词短语修饰A of B里面的A的，这说明located确实只修饰house，不会产生修饰brain的歧义...

在句首或句尾，且用逗号隔开的分词结构要尤其小心；因为有即可作定语，也可以做伴随状语的嫌疑。

这里的located....就有这样的嫌疑~ 如2楼所说

不同意LS，感觉过去分词短语还是就近修饰。

如D中 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.  located 还是修饰brain的
