Correct answer 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,

Subject + Adverb + Verb + Complement Subject + blah blah + is + blah blah blah

D and E although similar are just over wording statements

Do not see the reason why but I guess that like other similar English constructions in the GMAT, is all about what the examiners' preferred style is more than what it is grammatically correct i.e. adverb swap by the subject. You need to learn these tricks, and hope you get it right in the exam.

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.

that is the Official guide 12 edition explanation.
I dont understand why "which" here is not referred to A technique..

if you want to check is the question 107

hi noboru, I was under the same impression that 'which' is modifying 'emission' but that is not correct. "which" in A is correctly modifying "technique" . Actually "called proton-induced X-ray emission" is just a descriptive phrase for "technique" and "which" is modifying the extended noun phrase. Also, "proton-induced X-ray emission" is the name of the technique and the phrase "technique called proton-induced X-ray emission" has to be together and closer to "Originally developed for directing air pollutants".

Hope that makes sense.

IMO A.

All part (modifying immediatly preceding part or modifying the parts in the same clause) seems correct to me.

can anyone help to find out the principal clause and all the subordinate clauses. I think we are missing comma..
Here the principal clause has two verbs.

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,

BOOKMARKED
(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,

- Construction is A has correct modifier
Orginally developed ..., a technique x-ray emission, which...

(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,

Construction is C is such that the part called proton-induced x-ray emission has become a sub-ordinate clause which can be supressed. So rewriting the sentence supressing the clause shows that which after comma is redundant

If I were to write it correctly, I would say -
A technique originally developed for detecting air pollutants, called proton-induced x-ray emission, can quickly analyze the chemical elements in almost any substance without destroying it,

'which' modifies 'proton-induced X-ray emission' (a technique). so this is correct usage.

A...

Originally developed for detecting air pollutants --- is an opening modifier which modifies technique

called proton-induced X-ray emission --- is another modifier(Past participle) also modifying technique.

which can quickly analyze the chemical elements in almost---is modifying technique
any substance without destroying it

I picked A for this question:

A. Modifiers are placed accurately.

B. The problem with this answer is that the 2 initial modifiers should be modifying "a technique." However, "having" seems to modify the first modifiers. Also, these modifiers are misplaced because they should be placed on either side of "a technique."

C. Again, misplaced modifiers here. "Which" seems to be modifying "emission" - definitely incorrect.

D. Again, misplaced modifiers. "Which" is modifying "emission" - this is incorrect.

E. "Called proton induced X-ray emission" should be modifying technique. This is so far away from "technique" that is becomes confusing.

a. Correct
b. two lengthy modifiers
c. Called not next to Technique + use of comma before called
d. Called not next to Technique + use of comma before called
e. lengthy sentence construction + Called not next to Technique + use of comma before called
