Big doubt here ---- > What I have studied is "which" after comma refers to the noun before comma

Now, this is an OG question and according to my knowledge I of "which" I rejected (A) straight away because the "which" is describing emission is illogical -- but I am wrong why?

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,

That is absolutely correct. Relative pronouns like which , that, who, whom etc modify the noun before them. Now on to your problem

So what is "which" modifying => Closest noun => emission ? => wrong.

The noun is actually "proton-induced X-ray emission" . You can get this from the phrase "....technique called XXXX." Here XXXXX is the noun .

Hey Guys,
I have a doubt here, we say that pronoun must have an antecedent. In the current example, why "it" cannot be referred to technique and only substance. Has it to something in one sentence? Please clarify.

What a wonderful topic, because it is just not about modifications nor about wrong diction nor about wrong word order nor about wordiness. Each one choice is almost mking up to the grade except for some subtle slip.

The first split and the least cumbersome is that ‘can analyze’ is always preferred over ‘has the ability to analyze’. because of concision. On this score, We can get rid of B,D,and E

The confusion about the modification in A is because of the sandwiched noun that is modified left and right. As long as we appreciate that the phrase ‘called proton induced x-ray emission’ is a mere descriptive modifier of the noun technique and even if we cast it off, still it makes sense, then we can allude the relative pronoun to ‘the technique’, its most appropriate referent. So no issues with modification in A

You can see the awkwardness of the choice C. Here is a noun ‘a technique’ that is modified by 1. originally developed, 2. called proton- induced, and 3 which can analyze, all three running on without a single conjunction. So C is gone.

A is the winner

Kudos to the poster yuvrajpratap and Crick2000
