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~
