D is in passive voice! "Was more than doubled"! By whom was it more than doubled?

As a thumb Rule, prefer active to passive on GMAT(MAJORITY OF THE CASES)!

The number of vehicles on the road classified as "light trucks" in the United States increased by more than twice from 1980 to 1992.

a) increased by more than twice
b) increased more than two times
c) more than doubled
d) was more than doubled
e) had more than doubled

Meaning :
Number doubled/ More than doubled during certain period of time.

POE
a) increased by more than twice
Twice is adverb, Needs verb to modify. cannot be used as an object for preposition "by". (Some official question also test the same concept will edit the post if i manage to find it). Incorrect.

b) increased more than two times
Redundant - Increased more than two times - Sounds unidiomatic. Incorrect.

c) more than doubled
Correct - Subject (Number) Verb (doubled) pair is correct. "More than" is adverb. It is same as Number (fluff/Adverb) doubled during certain period.

d) was more than doubled
number was more than doubled during certain period. That is not intended meaning. we wanted to say, number doubles itself during certain period. Also, it is in passive voice.

e) had more than doubled
Unnecessary use of had , That is not intended meaning. we wanted to say, number doubles itself during certain period

increase and two times are redundant..
between c, d and e - was and had are not required as we are not sure of the time period..it is possible that we are in 1992..
Hence C is the answer

Dear experts,

Please confirm if the use of increase and more is redundant in option A & B

Actually "increased" should be followed by an absolute number, not a multiplier. Therefore even if one says "increased by double", the sentence would be wrong.

However assuming that you ignore the above mistake, then "increase" and "more" are not redundant. The word "increase" refers to the number of cars and the word "more" refers to the number 2; "number of cars" and "2" are two different items.

The phrase "increase by double" and "increase by more than double" are equally wrong. The latter is not more wrong because of any additional error of redundancy.

We usually say
The number increased from 50 to 100
The number doubled.

A. "The number increased by more than twice" from 1980 to 1992. ( which number are we talking about ? increased by more than twice modifies " The number". In effect - sentence A reads, the number from 1980 to 1992.
B. The number increased more than twice ( the increase happened more than two times, here increased is a verb)
C. The number more than doubled
D. The number was more than doubled ( by who ?)
E. The number had more than doubled( before what ?)

use of increased in option A and B is incorrect
In option D, use of was changes the tense of the sentence to past tense and also use of passive voice which is incorrect
unnecessary use of had in option E
correct usage is ' more than doubled '
correct answer - C

I believe A is wrong because it implies that "the increase (in the number of vehicles)" more that doubled from 1980 to 1992, but not "the number of vehicles" itself.
This means that if the increase was for example 2 cars per year, then during the course of 12 years, the increase became >4 (however many the number of vehicles were originally)
There is a very subtle difference. I got this question wrong too in the first attempt :/

Verbal experts, can you please confirm my explanation?

I there an article or post explaining this concept? I got little bit confused about this topic, because till today I never knew that "more than" can modify twice not "the number" as always assumed...

Hi Verbal Expert,

Is it right to use comparative degree in this way? -- I more than doubled my work from yesterday.

I could not think of any verb which can use comparative degree before verb. Please provide some example if possible. Thanks

A slight correction:
I more than doubled my work from yesterday to today.

Think it this way:
Suppose I doubled my work from yesterday to today.... what if today's work is not 2 times but 2.1 times yesterday's work. Then one way of expressing would be "more than doubled".

Thanks for the explanation !! That means comparative degree can be used before the verb. Correct me if I am wrong.
