请看道题：
OG-12 第107 题
Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can quickly analyze the chemical elements in almost any substance without destroying it, is ?nding uses in medicine, archaeology, and criminology.

(A) Originally developed for detecting air pollutantsa technique called protoninduced Xray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,
(B) Originally developed for detecting air pollutantshaving the ability to analyze the chemical elements in almost any substance without destroying it, a technique called proton-inducedX-ray emission
(C) A technique originally developed for detecting air pollutants, called protoninduced Xray emission, which can quickly analyze the chemical elements in almost any substance without destroying it,
(D) A technique originally developed for detecting air pollutants, called proton-induced X-ray
emission, which has the ability to analyze the chemical elements in almost any substance quickly and without destroying it,
E) A technique that was originally developed for detecting air pollutants and has the ability to
analyze the chemical elements in almost any substance quickly and without destroying the substance, called proton-induced X-ray emission,

key: A
OG解释：
in A the nonrestrictive clause which … is correctly placed next to emission and set correctly from the rest of the sentence by a pair of commas.
in C relative clause introduced by which.... incorrectly and illogically modi?es emission.
A 和 C 是同样的“emission, which”为什么A的which 结构是对的，C的which 就是错的呢!!!

问：which 在GMAT 中是否只能指代它紧靠的名词呢，如该题的A选项，只能指代emissions而不能指代proton-induced X-ray emission,如果是的，那么A怎么能对呢？？？

which是就近指代名词，就近指代的名词是包括其修饰的部分，这里的A和C都就近指代proton-induced X-ray emission。我觉得C错误的主要是句子重心变了，侧重点在 originally developed，而不是emission.因为这里的called只能做过去分词修饰 A technique 。不知道我解释的请不清楚。
慢慢你会发现，一般过去分词或是现在分词一般位于句首以及在句子中的地位居次要位置，不是句子强调的重心。

thanks very much, more clear.

however, 根据以上理论，A 中，called 不也是过去分词吗，那也不是强调的呀！！

请NN明示!!! 谢谢

A中的called是过去式，做句子的谓语，不是过去分词，过去分词是developed来形容a technique.
如果你把C中的两个动词都认为是过去式，那么需要一个and来连接。

called 是谓语，那么is finding是什么？

我觉得is finding才是谓语吧。。。
另外which不一定是就近指代的
