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
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 found this question very tricky because I could make no sense of it

What do statements A and B mean? doubling the increase?

(A) doubling the increase of
phrase refers back to the subject of the main verb "number of people..."

(B) doubling that of the increase in
"that of" does not have a clear antecedent.

(C) double as much as the increase of
"twice as much as" is the correct form

(D) twice as many as the increase in
"many" cannot be used as comparative for the subject "number", needs to be "much".

(E) twice as many as the increase of
same as D

+1 for A.

I am not very good with the double vs twice questions . But the general principle is that twice is an adverb , while double is essentially an adjective.

Slightly digressing... the number of is countable.. right? if yes then why much and not many? much is used for non countable..

Thanks

I agree with devinawilliam83. Double is the countable and can be used with idiom as many as. infact the use of "as much as" is incorrect here.

You are absolutely correct.

But what is the confusion ? C is not the correct choice because of the countable vs uncountable noun.
