A is the answer.As the introductory phrase refers to proton-induced x-ray emission and technique correctly modifies it.

C is wordy and awkward construction. In Gmat sentences which are concise and clear are preferred.

A for me too...
C and D distort the meaning by saying that the technique was originally developed....
B has issues with modifiers... The first dependent clause does not hav any connection with the rest of the clause...
E is incorrect because it has 'run-on' sentences.. Moreover it is wordy...

WHICH in A and C both refer to emission. But as per OG A is correct and C is incorrect.

Can anyone elaborate on this one?

Let us analyse these two sentences closely.Which is used to give in some additional information and non restrictive in nature .Remove the underlined portion and insert the remaining sentence into the original sentence .

When you do this only sentence a makes sense .Hope i make sense let me know if you are still not clear .

(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,

CORRECT


(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

The modifier starting with originally is too far from technique. so wrong


(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,

Why do you need a comma after pollutants? The initial modifer starting with A technique seems to modify called. wrong


(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,


which has the ability is wordy


(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,

has the ability ?? parallelism problem as well after AND. So, wrong

'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.

It is sort of confusing, but to me it looks like the "it" refers to "substance." It can't refer to the other nouns "air pollutants" or "chemical elements" because they are plural. That leaves the last noun "technique," but I don't think you can logically destroy a technique.

Hi there,

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 pronoun must not only have an antecedent but also have a logical antecedent.

According to this sentence, the proton-induced x-ray emission technique can quickly analyze the chemical elements in almost any substance without destroying it.

From meaning standpoint, this particular technique can analyze chemical elements in almost any substance and does not even destroy it. So where does it do the function of analyzing? In any almost any substance. So it does that function without destroying the substance.

Now, it is true that “chemical elements” does not agree in number with “it” and hence that cannot be the antecedent for “it”. Another singular entity is “technique” but it will make no sense to say that technique is used to so something without destroying the technique.

Hence, there is no problem with the reference of “it” in this sentence.

At e-gmat we cover in detail about grammatical antecedent and logical antecedent of pronouns in our concept called Pronouns.

Hope this helps.
Thanks.
Shraddha

In C and D, "developed" is parallel to " called" , so we need "and" to connect them.

There is no "and" so, C and D are wrong.
please, confirm/comment.

Hi there,

Yes, you are correct in saying that “developed” and “called” are parallel in the sense that both are verb-ed modifiers that modifies “a technique”.

Now, the usage of “called” or “named” is little different from other verb-ed modifiers. “Called” and “named” must be placed immediately after the entities they modify. They cannot be placed far away as seen in Choices C and D.
So yes, in a way we can say that placing only “and” without preceded by comma before “called” can solve this modification error. But, this will make the choices wordy. In choice A, both these modifiers are placed perfectly.
Also, there are “which” modification error in choice C and D. These also make choices C and D incorrect.

Hope this helps.
Thanks.
Shraddha

Hi there,

Let us split choice C into clauses:

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, is finding uses in medicine, archaeology, and criminology.
• A technique originally developed for detecting air pollutants, called proton-induced x-ray emission,
o which can quickly analyze the chemical elements in almost any substance without destroying it,
• (Cont. of Cl. 1) is finding uses in medicine, archaeology, and criminology.

“developed” is not a verb here. It’s a verb-ed modifier. The only verb that clause 1 has is “is finding”. (Click on the following link to learn how to distinguish between a past tense verb and verb-ed modifier: ed-forms-verbs-or-modifiers-134691.html#p1100855)

In choice C, “called proton-induced x-ray emission” has been separated from the entity it should modify – “a technique”. As a result, relative pronoun “which” is now only modifying the preceding noun “proton-induced x-ray emission”. It is not modifying “a technique” anymore. This leads to the modification error in Choice C.

Same is the case with Choice D as well.

Now let’s take a look at the correct Choice 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, is finding uses in medicine, archaeology, and criminology.

In this sentence, the opening modifier “developed” is correctly modifying the subject of the preceding clause “a technique”. Now another modifier “called…” is placed just after “a technique”. So here the sentence is really saying:
a technique = proton-induced X-ray emission
“a technique called proton-induced X-ray emission” makes one big noun phrase here and hence, “which” correctly modifies this entire noun phrase, including “a technique”.

Hope this helps.
Thanks.
Shraddha
