Finally I think it is B.

doubling that of the increase in -- Properly conveys the idea.

+ ing form is safe to use here to state the information in the past.



OA PLZ?

No answer is not B

C I guess


B is wrong . As it conveys the idea as the increase in the passangers in the current year lead to the increase in Previous year.


Double as much as the increase of

much is used for " increase.

C is wrong too

Refer OG 11 - 128

Doubling is awkward hence A and B is out,

The numbers are countable hence as many as should be used

In E, increase of is incorrect usage

Hence IMO D

D is not the answer

Man this is tricky. can you post the OA?

I am waiting for few discussions and good reasoning.
Will soon post it

Ok IMO A

You can bring down the answer choices to A and C.

D & E are out because 'the number' is singluar so you cannot use 'many'.

B is out because doubling 'that of the increase'. Your doubling the increase so what is the 'that' refering to.

Between C and A,

Doubling is a verb. Double is a noun.

Since your doing something to the increase of previous year (ie doubling it), you need the verb form.

Plus I think the idiom is twice as much as, not double as much as.

But my main confusion is twice vs double. When do you choose what. In this question you could easily eliminate the twice options, what about questions where you cannot eliminate.
If someone could shed some light on this difference it would be nice

I think, 'increase in previous year' is better than 'increase of previous year'. But, B and D are already ruled out. Now, I am confused

@karmayogi

I agree with you. Even I could not choose between increase of and increase in.
But then as they say, for SC you have to pick the best option, I found A better than the remaining.
If you face a similar situation in the GMAT and can't choose between in or of, look for other errors, they should guide you to the right answer.

OA is A

Hi mals24,

You gave a great explanation.

Doubling - Verb
Please correct me if I am wrong when we say "doubling the increase of the previous year" means this year's Passanger increase lead to the increase in the Previous year -- Giving a unclear meaning.

Thanks for the inputs!
