107. 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 finding uses in
medicine, archaeology, and criminology.

(A) 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,

(B) Originally developed for detecting air pollutants,
having the ability to analyze the chemical
elements in almost any substance without
destroying it, a technique called proton-induced
X-ray emission

(C) A technique originally developed for detecting
air pollutants, called proton-induced X-ray
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,

选A。

想问为什么不选C，A和C中which指代的区别，非常感谢。

多个修饰语修饰主语，最好的顺序是：
分词结构+主语+修饰语1+修饰语2+谓语

A和C的which指代应该是一样的

只是C中，主语 A technique和谓语called之间的逗号是多余的。

当主语有两个修饰词的时候，A选项是一切答案的标准公式~你可以多看一点题目总结一下~

C 一句话的主语谓语不能用逗号隔开

多谢各位同学指教。

我的疑问是OG上面解释C说，1. 正如这位同学说的，called不能用逗号隔开  2. relative clause introduced by which incorrectly and illogically modifies emission. 我的问题是，A不会有这样的问题吗？why

如果这样，确实是个问题
我觉得AC的which都指代临近的proton-induced X-ray emission

但是which也有跳跃指代的情况，晕了。。。

gmat928

原来没有做过OG12的题，现在又想了一下，似乎想通了。

这个题句子本意是a technique is finding uses in medicine, archaeology, and criminology。只有一个谓语is。

a technique后面的called是过去分词作定语，修饰technique。 所以a technique called proton-induced X-ray
emission这部分内容的核心词是a technique。

所以A中a technique called proton-induced X-ray emission, which can中的which内容向前跳跃修饰核心词a technique，逻辑意思上也应该是这样修饰。是technique 能怎样怎样。。。而不是technique的名称能怎样怎样。。。

再看看C选项called proton-induced X-ray emission的修饰成分前面加了个逗号，这个逗号太厉害了，which的跳跃能力再强也跳不过这个逗号，所以只能指代临近的emission了。

因此OG12中的解释说，A的which指代没问题，C中的which错误指代emission

恍然大悟。。。多谢多谢。。。

话说这题我从OG11想到OG12，从一战想到二战，终于解决了。多谢LS.

醍醐灌顶！谢谢您的解答，我就奇怪了which明明可以跳跃修饰，如A，那为什么C就错了呢。
