The subject in the sentence is United States. At the first glance,we may consider it as plural because of an extra 's'in states however it is singular. Therefore, 'it' is correct usage.
A, B and E eliminated-uses 'they'
The action in 1970 has already occurred before the action done in 1980. Based on this, D is eliminated.
C is the correct answer choice.

(A) twice as much of its national output of goods as they had - They cannot point to United States as it is a singular country.

(B) double the amount of their national output of goods as they did - Their cannot point to United States as it is a singular country.

(C) twice as much of its national output of goods as it did - This is correct.

(D) double the amount of its national output of goods as it has - Cannot refer to period in 1970 with present tense hence this is incorrect.

(E) twice as much of their national output of goods as they had - Their cannot point to singular country so incorrect.

Also double is a verb and cannot be used for comparisons. For comparison, we use twice, thrice etc.

(A) twice as much of its national output of goods as they had

The pronouns should jump out at us. We used "its" and "they" to refer to the United States. These pronouns refer to the same subject, which can't be both singular and plural. I can't eliminate this one fast enough.

(B) double the amount of their national output of goods as they did

Okay, "their" and "they" are at least both plural. But what is our subject? United States. Is the United States plural or singular? I actually had to think about this longer than I'd like to admit. I already gave a hint by asking "Is the United States...." instead of "Are the United States..."

Also, "double the amount of x as y" is not idiomatic.

(C) twice as much of its national output of goods as it did

"Twice as much x as y." That's a good idiom. So we're cool from an idiomatic perspective.

Pronoun check: "its national output of goods as it did....." "its and it" are both singular and clearly refer to United States. Great!

(D) double the amount of its national output of goods as it has

Our pronouns are in good shape, but our idiom is not.

(E) twice as much of their national output of goods as they had

I like this from an idiomatic perspective, but like we mentioned earlier, our "their" and "they" are not appropriate pronouns.

D and E are the next closest!

D has the correct pronouns, but idiomatically incorrect.
E is idiomatically correct, but incorrect pronouns.

(A) twice as much of its national output of goods as they had ---> use of they had at the end is incorrect should suggests us exported twice the amount of good it had in 1970

(B) double the amount of their national output of goods as they did ---> Double the amount is incorrect idiomatic usage

(C) twice as much of its national output of goods as it did ---> Idiomatic usage Twice as much x as y is correct use of it and its is correct

(D) double the amount of its national output of goods as it has ---> Idiom error same as B,

(E) twice as much of their national output of goods as they had ---> pronouns error their and they is incorrect usage

Official Explanation :

Choice A is incorrect because the plural pronoun they does not agree with its singular noun referent, the United States, and because had cannot substitute for exported.

In choice B, double the amount is a less idiomatic form of comparison than twice as much; also, the plural pronouns their and they are incorrect.

Choice C is best: the form of the comparison is idiomatic, the pronouns agree with the noun referent, and did - the simple past tense of do - can substitute for exported.

Choice D contains double the amount as well as has for exported, and

Choice E is faulty because of their and they had.

In 1980 the United States exported twice as much of its national output of goods as they had in 1970.

(A) twice as much of its national output of goods as they had - Pronoun issue "they" can't refer to the US

(B) double the amount of their national output of goods as they did - Pronoun issue "they" can't refer to the US ; double the amount is worse that twice as much

(C) twice as much of its national output of goods as it did

(D) double the amount of its national output of goods as it has - tense issue - it has ;

(E) twice as much of their national output of goods as they had - Pronoun issue "they" can't refer to the US

As per ellipses, option C becomes as-
In 1980 the United States exported twice as much of its national output of goods as it did (export) in 1970.

But for ellipses, shouldn't the omitted words be present in the first part of the sentence in the same form ? Here, exported and export are not in the same form.

------------------------------------------------ ------------------------------------------------ ------------------------------------------------
Ellipsis-
This is a case of ellipsis in comparison. In this, some words omitted from the sentence to make it more concise. Both noun and verb can be omitted. The omitted words should be present in the first part of the sentence in the same form.

-"Siri's AI capabilities are better than Alexa's (AI capabilities). - Correct! ("AI capabilities" is implied)

- Siri is smarter than Alexa (is). - Correct! ("is" is implied)

Siri is smarter than Alexa and Cortana are -- Here we CANNOT omit "are" since the verb in the earlier part is "is"?

Q1-For ellipsis, is it NECESSARY that the omitted words should be present in the first part of the sentence in the same form?

Q2- Also, are there any other rules/exceptions for ellipses other than two listed below.

The omission of a noun for concision is straightforward. Just make sure that the 2 nouns in the sentence can be logically compared. But there are certain exceptions when you are deciding -

1. Tense Shift-
If the verb tense changes from the first to the second half of the sentence, then the verb must not be omitted in the second half.

· You look more beautiful this year than last year. - Incorrect

· You look more beautiful this year than you did last year.- Correct

2. Meaning Ambiguity-
Do not omit the verb if doing so will make the sentence’s meaning ambiguous.

I love my dog more than my friend. - Incorrect -- ambiguity

·I love my dog more than I love my friend.- Correct!
·I love my dog more than my friend does.- Correct!

1/. The USA is a singular noun, so ''they'' (plurial) is incorrect.

2/. The USA exported as much as it did, not it had.

Some people are more comfortable referring to these helping verbs (or more accurately, helping verbs used this way) as pro-verbs. Whichever term you prefer, remember that this particular helping verb is a replacement for an existing verb, not necessarily in the same form. It is not just one part of the actual verb. At least in this case.

In 1980 the United States exported twice as much of its national output of goods as it did in 1970.
is
In 1980 the United States exported twice as much of its national output of goods as it exported in 1970.
and not
In 1980 the United States exported twice as much of its national output of goods as it did export in 1970. (unexpected meaning)

You can, without the risk of introducing ambiguity. The are is understood. For example, in she is smarter than her parents, we clearly don't need an are at the end.

Siri is smarter than Alexa and Cortana.
This sentence is fine, because there is no possibility of a comparison between Alexa and Cortana. The only issue is whether we are talking about Alexa and Cortana individually or together

Siri is more like Alexa than Cortana.
This sentence is ambiguous, but we won't remove this option without looking at the other options first.

Skywalker18 wrote:

No, but you shouldn't let the following exceptions determine your approach to all GMAT questions that test this concept.

Present tense
She likes cricket more than I do.
is
She likes cricket more than I like cricket.

Past tense
He scored more points in the game than I did.

Tense shift
Her son grew faster than she had.
is
Her son grew faster than she had grown.
In this sentence we don't want a did, to avoid giving the impression that they grew up together.

At 30, he has already achieved more than most other people ever will.

(A) twice as much of its national output of goods as they had

its and they is discrepant here so incorrect

(B) double the amount of their national output of goods as they did

as seems like used for causal relationship, so wrong.

(C) twice as much of its national output of goods as it did

seems good - as much as construction

(D) double the amount of its national output of goods as it has

has is wrong and also double

(E) twice as much of their national output of goods as they had

Meaning should be it exported x tons of it national output in 1970 and it exported 2x in 1980. but this option conveys it exported 2 times total output it had in 1970. so incorrect.

(C) twice as much of its national output of goods as it did

(D) double the amount of its national output of goods as it has

Main Issue:

1) Pronoun: US is a collective noun, and hence, it is singular.

(A) twice as much of its national output of goods as they had - Wrong: Pronoun 2) Verb. Should use past tense "did" instead of past perfect "had" since only one action happened 1970, an action not related to that of 1980.

(B) double the amount of their national output of goods as they did - Wrong: Pronoun

(C) twice as much of its national output of goods as it did - Correct

(D) double the amount of its national output of goods as it has - Wrong: Verb. Should use past tense "did" instead of present continuous "has" since the action happened in the past.

(E) twice as much of their national output of goods as they had - Wrong: Pronoun 2) Verb. Should use past tense "did" instead of past perfect "had" since only one action happened 1970, an action not related to that of 1980.
