Is it to eliminate (B) because of the word "annually" is unnecessary?

Here's what (B) says:

"...environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O'Hare International Airport is twice as much annually as is emitted by the..."

"Annually" isn't just unnecessary here -- it's 100% ridiculously redundant. You can sometimes get away with a little bit of wordiness on the GMAT, but there's no grey area on this one.

Correct I got it..
What is compared here?
amount of pollutant (emitted) at O'Hare international airport with amount of pollutant (emitted) by all motor vehicles in Chicago area.
In short phrase(amount of pollutant at O'Hare international) should be compared to phrase(amount of pollutant at Chicago)
a) It contains clause(presence of is being)
b)Clause(Presence of is)
c)Clause(Presence of what is annually)
d)Perfect phrase(that can be replaced by amount of pollutant)
e)wrong sense

(A) as much as that which is being emitted annually by all=> which is not preceded by comma
(B) as much annually as is emitted by the => redundant
(C) as much compared to what is annually emitted by all => same error as E
(D) that emitted annually by all => correct and no mistakes
(E) that emitted annually compared to the => twice and compared are redundant

Similar Question from OG : [LINK]

Can someone explain why you would say "twice that" instead of answer C? Is it just become it's more concise? Can we say twice as much? Or is that considered wordy?

D is clear winner here.

(D) Providing initial evidence that airports are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O'Hare International Airport is twice that emitted annually by all motor vehicles in the Chicago metropolitan area.

here that = the total amount of pollutant
my question is, why not
that = the total amount of pollutant emitted annually

In that case, is the following correct?

Providing initial evidence that airports are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O'Hare International Airport is twice that by all motor vehicles in the Chicago metropolitan area.

Just want to clarify what can we include within an ellipsis, and what we cannot.

A pronoun ideally refers to a noun (or a noun phrase) only. It is not recommended to use a pronoun to refer to a noun along with a noun modifier.

Here the pronoun "that" refers to the noun phrase "the total amount of pollutant " - it would be questionable to use the pronoun to refer to the noun phrase "the total amount of pollutant" + noun modifier "emitted annually" together.

The answer if you look closely is

the total amount of pollutant emitted annually is twice as much as that which is being emitted annually by all motor vehicles in the Chicago metropolitan area. Option A doesnt make sense.
In option D we have

the total amount of pollutant emitted annually is twice that emitted annually by all

(A) as much as that which is being emitted annually by all
(B) as much annually as is emitted by the
(C) as much compared to what is annually emitted by all
(D) that emitted annually by all - Correct. "that" refers to "the total amount of pollutant" so sentence becomes.

In A,B, and C, "emitted" is used as verb in non underlined part, but in underlined part "emitted'' is used as verb. So, they all are out.

The first "emitted" (in non-underlined part) has been used to introduced the new info, but the 2nd ’’emitted’’ (in underlined part) has been used as verb directly.

Hi GMATNinja,
I'm little bit confused about the use of the word "annually" in B and in D. Why "annually" is redundant in B, but not redundant in D?

(A) as much as that which is being emitted annually by all
(B) as much annually as is emitted by the
(C) as much compared to what is annually emitted by all
(D) that emitted annually by all
(E) that emitted annually compared to the

In short, the correct choice D is:
The total amount of pollutant emitted annually by X is twice that (the total amount of pollutant) emitted annually by Y.

(A) as much as that which is being emitted annually by all. This is wordy which makes it redundant.
(B) as much annually as is emitted by the. Annually and emitted cannot be separated.
(C) as much compared to what is annually emitted by all. Wrong/incomplete 'as much as ' idiom.
(D) that emitted annually by all. Correct.
(E) that emitted annually compared to the . Wrong comparison.
