In nests across North America, the host mother tries to identify their own eggs and weed out the fakes, but the brown-headed cowbird – a brood parasite that sneaks its eggs into other birds’ nests – produces eggs that look very similar to those of the host, making that task surprisingly difficult.

Hi

"NEED EXPERT ADVICE"


B) the host mother tries to identify its own eggs and weed out the fakes, but the brown-headed cowbird – a brood parasite that sneaks its eggs into other birds’ nests – produces eggs that look very similar to that of the host, making it surprisingly difficult

The second that should be those > I saw different replies on this issue.

Some say it denotes the object and some say that because of the plural eggs.

Please throw some light on this topic.

Also plz explain the usage of "that" .

I would really appreciate your help guys :)


Responding to a pm:

There is a comparison here:

...but the brown-headed cowbird produces eggs that look very similar to that of the host..

the eggs should look similar to the eggs of the host. The comparison is between the two types of eggs. Hence, you need the plural "those" here. "those" will be a placeholder for "eggs"

So the correct sentence would be: ...but the brown-headed cowbird produces eggs that look very similar to those of the host..

The first "that" starts an essential modifier.
the bird produces eggs that look ....
It describes the eggs the bird produces by saying that the eggs look very similar to the eggs produced by the host.



Hi Karishma
thnx for your reply but am still not able to understand why "those" and not "that" :roll:

1. eggs that look very similar to that of the host
2. eggs those look very similar to those of the host

3. eggs that look very similar to those of the host

can you plz help me out ..!! :idea:


That can be used to refer back to the antecedent (antecedent means it takes the form of the logical noun before it) in places. It can be confusing but in this case. It is says: eggs that look very similar to eggs of the host. Instead of writing eggs again English allows us to use a pronoun. For instance if you said Karashma answers my inquiries. Karashma like blank... To make it flow better you would say she the second time .Karashma answers my inquiries. SHE like blank.. She clearly refers back to karashma. Hence Karashma is the antecedent and she is the pronoun that refers back to her.

Similar to this sentence you could say eggs or a pronoun. That is a singular pronoun. Those is plural. So you use those.

The pronouns
That- Singular
This - Singular
These-plural
Those-Plural

These and this is typically possessive. Such as this is my food. These are our belongings. And those is for external parties.. Anyways, the GMAT doesn't really test the difference between that/this these/those but good to know.

B) the host mother tries to identify its own eggs and weed out the fakes, but the brown-headed cowbird – a brood parasite that sneaks its eggs into other birds’ nests – produces eggs that look very similar to that (that is wrong as that refers to eggs and eggs is plural therefore we need to say those) of the host, making it (it is also unclear but sometimes GMAT doesn't care about this but this should heighten suspicions. It is kind of unclear what it could be and you need to deduce it means task, which is not good writing. ) surprisingly difficult

The answer is C
"Host mother" is taken as a plural subject because of "In nests across North America"
It should have proper antecedent
Only C clear these errors .

Hey VeritasPrepKarishma GMATNinja

I got this question correct as there were clear errors in all other errors options. I have just one doubt in Option C

Leaving a word only in its possessive case (not followed by what it is possessing) - is it correct?

It can mean anything here
Eg: - bird's eggs, bird's nest, bird's xyz

Is it grammatically correct to leave a word only in its possessive case?

Yes, it is in case of parallel structure.

My painting is just like Pete's.

It is obvious that we are talking about Pete's painting.
