Not convinced either, it looks like the sharp raise in 1990 is doubling the increase of previous year. Like previous year if the raise is X, 1990's raise is making it 2x (previous year's)

I prefer B!!.. Experts help needed here please!!

'that' in B does not have clear referent. C has modifier problem. D and E use 'many' for non-countable noun. So, A.

I would go for B. "the number... rose sharply in 1990, doubling that of the increase in..." follows parallelism.

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


Simple and Tricky and not many explanation on this. I encountered it in the GMAT prep test and chose random as I couldn't figure out .. though I suspected A and C

later on what I understood - after comma whatever comes need to modify/explain the sentence... absolute phrase

In such scenario, C, D & E type of construction does not work .. Correct construction would be something like this ...The man is twice as old as his son
So we are left with a and b; Out of this a is correct as ... B changes the meaning

Hi All,

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

Let’s first understand the meaning of this sentence. The year 1990 experienced a sharp rise in the number of people flying first class on domestic flights. This rise doubled the increase seen previous year.

Error Analysis:

This sentence uses verb-ing modifier “doubling” preceded by a comma. This means that this modifier will modify the entire preceding clause. Usage of “doubling” is correct here because it correctly presents the result of the preceding clause. There was a rise sharp in the number of specific passengers. This rise doubled the increased witnessed the previous year. Hence there is no error in this sentence.

POE:

a. doubling the increase of: Correct for the reason stated above.

b. doubling that of the increase in: Incorrect.
1. There is no antecedent of pronoun “that”.
2. When we say “increase in something”, the phrase means that “something” has increased itself. Hence, this phrase does not make sense in this choice as it suggests that “the previous year” increased itself.

c. double as much as the increase of: Incorrect.
1. Here “double”, a noun modifier has no particular noun to refer to.
2. The correct way to say is “double the increase” and not “double as much as the increase…”.

d. twice as many as the increase in: Inocrrect.
1. Noun modifier “twice” dos not have a noun to refer to.
2. Use of “many” for uncountable noun “increase” is incorrect.
3. Repeats the idiom error of choice B.

e. twice as many as the increase of: Incorrect. This choice repeats the first two errors of Choice D.

Hope this helps.
Thanks.
Shraddha

A, 'doubling' is used correctly for 'increase of' and number of people shouldn't have any influence in the second sentence

Simplify: The number rose sharply, doubling the increase of the previous year.

Quote:
A. doubling the increase of

The number doubled the increase.
Quote:
B. doubling that of the increase in

The number doubled the last year's number.
Quote:
C. double as much as the increase of

Incorrect idiom "double as much".
Quote:
D. twice as many as the increase in

The number compared to the increase. Many -> much,
Quote:
E. twice as many as the increase of

As D.

I pick B, but remain curious about the original explanation. Please provide the OE!

In the origional sentence 'doubling' explains the effect of the 'rise' hence correct. No other option conveys this meaning of 'effect', hence option A is the correct one.
