USE OF WHICH MODIFIER

[RonPurewal]

But can I say," I took pictures of my dog, which is so adorable."?
Is refers to my dog.

Thanks!

Sure. What makes you think you can't?

Hi,Ron,I am confused about the usage of "which".
there is a small part of an OG sentence.

A technique originally developed for detecting air pollutants, called proton-induced X-ray emission, which can quickly......

here,why "which" modify the "emission" not the "proton-induced X-ray emission" as a whole?please clarify,thanks a lot!

"Which" can't skip over an entire modifier enclosed by commas.

The only thing that "which" can skip, in that way, is 1 prepositional phrase. I.e., "which" can modify one of the following two types of things:
* Noun
* Noun + prep + noun
As far as GMAC's current output is concerned, that's all we've seen.

Hi,Ron, thanks for your reply, I am still confused, I regard the "proton-induced X-ray emission" as a whole noun, because it is the name of a techinique, why "which" modify a part of the name "emission",not modify the whole name? please shed more light on,thank you very much!

You're not thinking about the right issue.

As you wrote, we're talking about a name, not a process. ("Called xxxx" means that xxxx is a name.) There's no potential ambiguity"”the same noun can't refer to a process and to its name at the same time.

Names can't quickly do xxxx stuff; only chemical processes can.

In any case, this is the end of the discussion of the x-ray emission problem.
That's an OG problem. We're not supposed to be discussing it on the forum at all.

Further posts about the OG sentence will be deleted, unless someone can provide a screen capture proving that the same problem also appears in GMAT Prep.

Thanks.
