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

i) doubling the increase of
ii) doubling that of the increase in
iii) double as much as the increase of
iv) twice as many as the increase in
v) twice as many as the increase of

I went with choice V, let me know your comments which answer choice you think is correct?

Thanks
VIvek

Can you explain clearly i didnt get it

Schandok;

Please avoid haste;

1.It is not ‘through the 90’s’ that the text is referring to. It is just the year of 1990 in comparison to the previous year.

2. Even if it is through the 90’s, it is a thing of past and it is not an on- going thing now.

3. Doubling is not used in a progressive sense here. It is a used as a present participle.

What is in comparison here? It is the increase this year compared to the increase last year. Increase is used as a non-countable noun and therefore singular in nature.

So countables such ‘as many as’ are unidiomatic. D and E are out.

In C, ‘double as much as the increase ’ is redundant because the doubling itself is of the increase;

B is wrong for again using a redundant phrase of ‘doubling that of’

Eventually A is the remainder, evading all the errors and keeping it brief and correct

If you are asking me, then I wish to say, that I never considered comparison from year to year as progression. By progression I hope you mean ‘going forward’ or ‘moving ahead’. I haven’t said any of that sort.

Secondly it is a plain compriosn between 1990 and 1989, its previous year. How do you surmise that it is form year to year?

I did not get what the gist of your second query is. ‘Doubling’ is making or rising 100% more( both countable – as in doubling the number of seats in the auditorium and and non-countable as in doubling the capacity of the tank ) ; ‘as many as’ is a simple positive degree of comparison between two countable nouns.

Or am I missing your point?

I said 'in a progressive sense" meaning that it is not be used as ' is doubling' i.e present continuous tense. I did not say progression

P.S: For your earnestness in analyzing this topic, I feel you deserve a Kudos.

+1 for A.

I arrived at A by finding faults in other choices.
