"Increased by more than twice" is considered redundant in GMAT , instead you can say "more than doubled" which is more precise and less wordy.

Because of this we drop answer choices A & B. Also we drop E because no need for "had" because there is no sequence of actions in the past.

Finally between C & B , we drop B because it uses passive voice, meaning number by doubled by itself. (Also GMAT doesn't like passive voice)

Answer is C here, "more than doubled"

Press +1 if this helped

Agree - except probably a typo - you drop B, instead of drop C.

If you really wanted to have an answer that begins with "increased by x..." -- a better choice would be to change it to "increased by more than two-fold" instead of "increased by more than twice" --- but of course simplest is always best if another simpler option exists (c).

Here is another good explanation.
source https://www.manhattanprep.com/gmat/foru ... t7028.html

In the original sentence, "increased by more than twice" is unidiomatic; when numbers increase, they "increase by more than a factor of two." Also, "twice" is an adverb; only nouns can follow the preposition "by."

Answer choice (B) introduces an issue in meaning. When the number of degrees "increased more than two times," that means over the period of 1978 to 1985, it has gone up at least twice: maybe in 1980 and then in 1981. The other times, it has stayed steady or gone down.

In answer choice (D), "was more than" demonstrates a comparison: "The number of pennies was more than the number of nickels." It doesn't make sense for us to say "the number ... was more than doubled": we cannot compare "number" with "doubled" since doubled is not a noun.

The past perfect tense "had more than doubled" in (E) is not justified. The past perfect is used when there is a comparison between one past action with another past action (or past time marker). In this sentence, we're not comparing "the number ... had ... doubled" with any other time reference.

(C) is correct because "doubled" is used correctly in the simple past.

Hope that helps.

This is how i arrived at option C.

(A) increased by more than twice [Use of increased and more is redundant.]

(B) increased more than two times [same as option A]

(C) more than doubled [Correct and most logical answer of all]

(D) was more than doubled [incorrect]

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.

sayantanc2k Why 'had'must not be used. One explanation I read somewhere cites that it is because only 1 verb is here. Can you please tell more on the same. *Clueless*

Thanks!

(A) increased by more than twice

(B) increased more than two times

(C) more than doubled

(D) was more than doubled

The correct answer here is C. Lets understand the question. The question presents a statement, which is a fact. The fact as mentioned in question stem. Lets come to evaluation of choice.

(A) increased by more than twice - increased, more represents the same thing.

(B) increased more than two times - Doesnt sound correct

(C) more than doubled - Correct

(D) was more than doubled - Unnecessary use of tense here

(E) had more than doubled - Unnecessary use of tense here

First, recollect that a past perfect tense is used to depict that an event occurs prior to another event in past.

In option E, the verb "had doubled" is in past perfect tense, but there is no reference of another verb with simple past tense in the sentence. Hence the reason above is correct - in order to use past perfect, you must have another verb in simple past ( or at least a time reference) before which the verb in past perfect occured.
