SC: The population of India has been steadily increasing

[cesar.rodriguez.blanco]

I do not how how to solve the following SC.
B is out because of "they".
But what about the other options?

The population of India has been steadily increasing for decades, and it will
probably have what is estimated as 1.6 billion people by 2050 and surpass China
as the world's most populous nation.
A. it will probably have what is estimated as
B. they are likely to have
C. the country will probably have
D. there will probably be
E. there will be an estimated

The population of India has been steadily increasing for decades, and it will
probably have what is estimated as 1.6 billion people by 2050 and surpass China
as the world's most populous nation.

A. it will probably have what is estimated as

if refers to population, but it should refer to India. out

B. they are likely to have

As you said they has no clear antecedent. out

C. the country will probably have

Correct. The sentence reads

The population of India has been steadily increasing for decades, and the country will probably have 1.6 billion people by 2050 and [the country will] surpass China as the world's most populous nation

We solved the problem with the antecedent. Also the second part of the sentence
surpass China as the world´s most populous nation has the correct subject.

IMO if the antecedent comes in a prepositional phrase it is better to repeat, or look for another word, than to use a pronoun.

D. there will probably be

The population of India has been steadily increasing for decades, and there will probably be 1.6 billion people by 2050 and surpass China as the world's most populous nation

we have no subject for surpass China as ...

E. there will be an estimated

same as D

B is out because of "they".
But what about the other options?

in (d) and (e), there is no actual indication that the 1.6 billion people will be in india. those choices just say "there will be", which is an idiomatic expression that doesn't indicate a place.
takeaway: "there is/are" / "there was/were" / "there will be" / etc. DOES NOT INDICATE A PHYSICAL LOCATION. unlike most other uses of "there", in which "there" actually stands for some place, this "there" doesn't stand for anything.

if you want to use "there is" in reference to a particular location, you have to state the location, explicitly, elsewhere in the sentence.
ex: there are three cars in the driveway.

--

(a), the only remaining choice, is redundant (there's no reason to use both "probably" and "estimated"). additionally, "what is" doesn't make any sense.

Hello Ron ,
I understand C is correct.
But in option D and E regarding the usage of there
I thought there can refer to a place in prepositional phrase
If it is , cannot " there " in second clause refer to a place in prepositional phrase of first clause?

Thanks

i'm sorry, but i don't understand your question. (too much terminology that i don't know.)

but—as always—if you need to use that much terminology, you're overcomplicating the issue.

look at how the sentence is structured:
....and surpass China as the world's most populous nation
this is something that clearly must have 'india' as its subject.
i.e., this sentence will not work unless it says that India will xxxxxxx and surpass China...

so choices b, d, and e are gone immediately.
