TWICE or TWO TIMES is the FREQUENCY. On the other hand DOUBLE is QUANTITY X 2.

Ex. The stock prices of the company DOUBLED when they rose sharply TWICE in the same day.


We could also use twice to indicate a multiple x2, isn't it?

My age is double your age.
My age is twice as your age.
I am two times as old as you.

All the above three sentences mean the same, isn't it?.. none of them refer to frequency, but to a multiple.

The point is, twice or two times could be used for two different meanings:

1. frequency, as you stated (because of the word times)
2. multiple x2, as I mentioned above.

However double can only be used to refer to the multiple x2.

The number of people flying first class on domestic flights rose sharply in 1990, doubling the increase of the previous year.

A. doubling the increase of - -ing participle word correctly links the second part sentence of the sentence to the first.
B. doubling that of the increase in - that does not refer to anything
C. double as much as the increase of . - double and "as much as" are both comparison words. "as much as is used for uncountable things"
D. twice as many as the increase in - twice and "as many as" are both comparison words - Redundancy
E. twice as many as the increase of - twice and "as many as" are both comparison words - Redundancy

A. doubling the increase of
B. doubling that of the increase in
C. double as much as the increase of
D. twice as many as the increase in
E. twice as many as the increase of


I think it's D.

But OA is A...WHY??

the number of people is countable so many can be used.

Because GMAT prefers more concise wording, "twice as many as" can be expressed as "double" replaces the word. That's why C, D , E are out.

Between A & B, B is out because doubling that of the increase in previous year" should be "that of previous year" or it shouldn't be using "that of".

In my opinion Answer is A is most suitable one.

+1 if this helped :wink:

How does one go ahead. I was stuck between Aand B. I was trying to see where the pronoun was pointing to. Please advice


(B) is incorrect because "that" has no antecedent. We need to double the increase but "increase" is not mentioned before "that".

what is the difference between A and B? CDE are clearly wrong, but is it that the word 'that' in B has no referent and thus B is wrong?



Yes, in option (B), "that" is used as a pronoun. It needs to have an antecedent. But it doesn't.

(B) The number of people flying first class on domestic flights rose sharply in 1990, doubling that of the increase in the previous year.

What does "that" stand for here?

"that" stands for "the increase" but it hasn't been mentioned before.

e.g.
Democrats have rated the U.N. more positively than Republicans, with Democrats' average approval rating (46%) nearly doubling that of Republicans (24%).

"that" stands for "average approval rating". The pronoun needs an antecedent.

In option (B), the pronoun "that" has no antecedent.
