Friends,

105A. 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

And OG says, the non-restrictive clause "which...destroying it" is correctly placed next to "emission".

Do you think that "this sentence implies that "which" modifies correctly "emission"?If so, please see more on other OG

105.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, is finding uses in medicine, archaeology, and criminology.

Og says, relative clause introduced by "which" incorrectly and illogically modifies "emission"

Thanks

In 105C, "called proton-induced X-ray emission" has no clear referent. This, in turn is followed by a non-restrictive clause. To me, "ambiguous referent" itself makes this answer choice wrong.

I see the following flaws:

1. What exactly is "proton-induced X-ray emission"? Is it a technique or air pollutants? So ambiguity is there.

2. Also two phrases ("called proton-induced X-ray emission" and "which can quickly analyze the chemical elements in almost any substance without destroying it") at a time are not correct:

I think OG s wording is getting you confused.
which is placed close to emission in A and the clause beginning with which is modifying a technique.
In C which is placed near emission but a technique is no where near emission. In A which is modifying a technique. C has so many other errors as already explained by other members in the thread.

"Originally developed for detecting air pollutants, a technique called proton-induced X-ray emission, which can"
"Which" modifies "a technique" and not "emission"
