105. 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,
Rhetorical construction
The original sentence successfully avoids the problems that may occur in a long sentence with multiple modifiers. The sentence opens with the modifier originally developed for detecting air pollutants. This participial phrase is immediately followed by the word technique that it modifies; technique is in turn followed by the phrase called proton-induced X-ray emission. Finally, the non-restrictive clause which ... destroying it is correctly placed next to emission and set off from the rest of the sentence by a pair of commas.
A Correct. The modifiers are all correctly placed
B Placement of two long modifiers at the beginning of the sentence is awkward and makes it difficult to locate the subject, 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 introduced by which incorrectly and illogically 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 clause introduced by which incorrectly and 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; has the ability to is wordy
对答案没疑问。
但是不理解OG红色部分的解释，OG认为CD的which修饰emission错，
可是正确选项A的which不也是修饰emission么
是不是因为A的called proton-induced x-ray emission为修饰成分，所以which不就近指代emission,
而是跳跃修饰technique呢？
谢谢指教！
自我总结：
sth called X，which… 中：which 指代 sth;
sth，called X，which… 中：which 指代 X;
自我总结：
sth called X，which… 中：which 指代 sth;
sth，called X，which… 中：which 指代 X;
只能这样理解了!
这个题中的Which指代还是不清楚，NN们快帮忙啊
One more question about 限制性 和 非限制性定语从句
from og：
A：which 引导的为 非限制性从句
C,D: which 引导的为 限制性从句
为什么啊 非限制从句不是有逗号分开吗 C;D 也分了呀！！！
在GMAT中，碰到2个modifier（2M）的情况时，一般S,M,M,VO是错误的结构，因为S和VO离得太远。
比较常用的结构是M,S,M,VO，这样比较清楚，也不容易出现M和M之间互相修饰的问题。
M,M,SVO也有可能是正确的选项，比如OG102，但是一般来说M,M,SVO这种结构会造成OG中说的“Placement of two long modifiers at the beginning of the sentence is awkward and makes it difficult to locate the subject”
哎，我觉得OG的矛盾之处太多了！
OG11－102中
Beatrix Potter, in her book illustrations, carefully coordinating them with her narratives, capitalized on her keen observation and love of the natural world.
(A) Beatrix Potter, in her book illustrations, carefully coordinating them with her narratives,
(B) In her book illustrations, carefully coordinating them with her narratives, Beatrix Potter
(C) In her book illustrations, which she carefully coordinated with her narratives, Beatrix Potter
(D) Carefully coordinated with her narratives, Beatrix Potter, in her book illustrations
(E) Beatrix Potter, in her book illustrations, carefully coordinated them with her narratives and
OG解释E错误之处在于“Them cannot refer to book illustrations because the plural noun is the object of the preposition in;”
但在本题中 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, 选项中除了E外其余四个中的it不就是指代介词短语中的subtance吗？102中不是说这样指代是不可以的吗，为什么这里又可以了，真是头疼。 难道是因为in her book illustrations是个插入语就要受委屈哇？？
