GMATNinja, Bunuel, can you please help to clarify why including cannot be referred to the nests?
VeritasKarishma, thank you for providing some clarification on this. I am still not clear whether verb-ing should be used essential words. eggs is an essential word-->> verb-ing should be used to modify it, not nests.

Hello tkorzhan1995,

We hope this finds you well.

Having gone through the question and your query, we believe we can resolve your doubts.

As VeritasKarishma wrote, here "including" is used to introduce the examples of the birds "warblers, vireos, flycatchers, and thrushes", and thus must logically refer back to "birds" rather than to "nests".

Further, it cannot be used to modify "eggs", as "eggs" here refers to the cowbird's eggs; modifying "eggs" with "including warblers, vireos, flycatchers, and thrushes" would illogically imply that warblers, vireos, flycatchers, and thrushes are examples of cowbird eggs. There is no rule that limits which nouns in a sentence can be modified by a present participle ("verb+ing"). So long as the meaning it conveys is correct, a present participle can modify any noun in a sentence.

We hope this helps.
All the best!

Hi AndrewN,

I hope you're doing fine.

This question caught my attention after receiving it my PM. Though, (D) is the correct choice here, and I do refute that, (C) doesn't look half bad.
Many experts, including Charles, have opined on the "ambiguity" surrounding the usage of "those" in (C), citing it can refer to "eggs". But, as per logic, "those" can refer only to "the nests". Pronoum ambiguity is an issue when one can construe multiple meaning through a sentence because of the placement of an "ambiguous" pronoun. But, here I believe, the second meaning is being forced to cause "pronoun ambiguity", for, per logic, no bird can lay eggs of an another bird in nature. So, "those" can refer only to "the nests" here.

(C) female cowbirds use the nests of other birds to lay up to 40 eggs a year, including the nests of warblers, etc.

Here, "including the nests of x,y,z" refers to "the nests of other birds" in the preceding clause, and the "including the nests of x,y,z" phrase adds information about the group of "different nests" that cowbirds use to lay eggs. And this meaning doesn't look bad to me.

What are your thoughts on this?

Hello, PyjamaScientist. Have you looked at this earlier post of mine? In it, I discuss how even in a rearranged sentence in which those of was right next to the nests of other birds, I would still prefer (D). In short, the nests of other birds already makes it clear that including encompasses nests.

Furthermore, ambiguity of meaning does not always mean that there are two (or more) legitimate ways of interpreting something, just that it may take a moment to sort out what something refers to. On first read, going left to right, it is confusing to hit female cowbirds use the nests of other birds to lay up to 40 eggs a year, including those of, because we are not accustomed in writing to having to reach back over two plural nouns to land on the one that makes the most sense. A better composed sentence should put the reader in a position to do less work.

Thank you for thinking to ask.

- Andrew

I got this correct as D seemed only the correct choice. But I am confused with comma + verb-ing modifier. The rule for comma + verb-iing modifier is that it modifies the entire preceding clause (to confirm this the subject of verb-ing modifier and the subject of the preceding clause must be same). Here verb-ing modifier modifies the preceding noun and not the preceding the clause. Hence, should not comma be eliminated?

I would really appreciate a response of someone in this regard to clear the doubt.

'including' is used as a preposition here, not verb-ing.
