请教OG13上SC一道题目：关于which的指代

luobotou1992

106. Originally developed for detecting airpollutants, a technique called proton-induced X-ray emission, which can quicklyanalyze the chemical elements in almost any substance without destroying it, is finding uses in medicine, archaeology, andcriminology.

(A) Originally developed for detectingair pollutants, a technique called proton-induced X-ray emission, which canquickly analyze the chemical elements in almost any substance withoutdestroying it,

(B) Originally developed for detectingair pollutants, having the ability to analyze the chemical elements in almostany substance without destroying it, a technique called proton-induced X-rayemission

(C) A technique originally developed fordetecting air pollutants, called proton-induced X-ray emission, which canquickly analyze the chemical elements in almost any substance withoutdestroying it,

(D) A technique originally developed fordetecting air pollutants, called proton-induced X-ray emission, which has theability to analyze the chemical elements in almost any substance quickly andwithout destroying it,

(E) A technique that was originallydeveloped for detecting air pollutants and has the ability to analyze thechemical elements in almost any substance quickly and without destroying thesubstance, called proton-induced X-ray emission,

OG的解释说：A当中which指代的是对的，而C和D 都不对，可是我不明白，A C D 三个选项中which前面紧跟的都是emission，which不是应该指代离它最近的那个么？为什么A指代的是对的，C和D中的指代就不对了啊？

Rhetoricalconstruction

The original sentence successfullyavoids the problems that may occur in a long sentence with multiple modifiers.The sentence opens with the modifier originallydeveloped for detecting air pollutants. Thisparticipial phrase is immediately followed by the word technique that it modifies; technique is in turn followed by the phrase calledproton-induced X-ray emission. Finally,the nonrestrictive clause which … destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair ofcommas.

A Correct. The modifiers areall correctly placed and punctuated; the meaning is clear.

B Placement of two long modifiers at the biginning of the setence is awkward and makes it difficult to locate thesubject; second modifier (having…) actually modifies the first modifier.

C Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clause introducedby which incorrectly andillogically modifies emission.

D Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; relative clauseintroduced by which incorrectlyand illogically modifies emission; has the ability to is wordy.

E Called proton-induced X-ray emission should be placed next to a technique and should not be set off by commas; hasthe ability to is wordy.

Thecorrect answer is A

跪求大神回答啊，5月29考了呜呜~

这个我也不明白！！

给你看看我刚发现的一个帖子 说不定有用 至于另外两个选项 我觉得是不是因为which离得太远，不能指代technique，只能指代离得最近的emission 啊= =

C D中called的位置肯定不好。相对于A的which，不管是修饰technique还是emission，都可以，因为technique和emission是平行的。

不是大神，但就LZ问题和以上几位的回答谈谈看法：
OG里已经很清楚的告诉我们，called proton-induced X-ray emission，在这里就是定语，是修饰A technique的，所以解释中说called proton-induced X-ray emission要绝对跟在A technique后，而且没有逗号分隔。所以A选项就是a technique called proton-induced X-ray emission，这里 X-ray emission就是a technique的修饰部分，核心名词只有一个就是a technique，后面which定语从句修饰也必须是它的核心词a technique。

再来看C,D，选项， called 位置不对，以及被逗号分隔，called proton-induced X-ray emission从定语变成状语。所以我们可以看到，called proton-induced X-ray emission在这里就没有紧邻的核心名词修饰，所以后面的which从句就不可能修饰a technique，而必须去修饰这个状语中唯一的名词X-ray emission，这样就会引起了逻辑意思的错误，所以C,D，选项的修饰是错误的。

亲~你的意思是说C D中的called有可能修饰到air pollutants而不是technique么？
