# Thread: double Vs. twice Vs. two times

1. ## double Vs. twice Vs. two times

I have three questions below that test the usage of double, twice and two times. I am confused as to what to pick. I usually look for other errors and use POE to get to the correct answer. Is there any method to this madness?

universities in the United States increased by more than twice from 1978 to 1985.

(A) increased by more than twice

(B) increased more than two times

(C) more than doubled

(D) was more than doubled

Today, because of improvements in agricultural technology, the same amount of acreage produces double the apples that it has in 1910.

(A) double the apples that it has

(B) twice as many apples as it did

(C) as much as twice the apples it has

(D) two times as many apples as there were

(E) a doubling of the apples that it did

Shaq - I think these types of questions can be readily answered "by ear"

1. C is correct.

A - increased more than twice - well how about simply saying "more than doubled". Conveys the same info much more succinctly.

Choice B says "increased two times" implying not that the proportion doubled but that the degrees increased in numbers on TWO OCCASIONS

D - was more than doubled -- Number of degrees WAS more than doubled -- the test makers have craftily introduced a Subject Verb agreeement error while correcting the usage error.

E - Had more than doubled - No reason to add the past perfect when the simple past suffices.

2 - B is correct.

A - look closely - the same amout of acreage produces "double the apples that it HAS" -- why HAS when it implies something that WAS accomplished from the same acreage ostensibly in the PAST?

C - As much as twice the apples - as much as is used to denote equality NOT QUANTITY as the sentence implies.

D - awkward and wordy

E - acreage produces A DOUBLING of the apple - can't quite imagine how an "acreage will produce a DOUBLING" ..

3. C is correct
A - what does the THEY point to - United States is singular
B - Same problem as A
D - As it HAS? Tense problem
E - Same as A - They is inapproriate.  Reply With Quote

Yes, C B and C. Thank you dwivedys. I get antsy when I choose answers 'by ear' . I was able to answer the above 3 questions correctly, but was concerned if there was another method to do so. I figured if there is logic behind my choice, I can be more confident.  Reply With Quote

double is the verb form of twice. so, for example, we cant use it with produce.

and the idiom is twice as many [...] as.  Reply With Quote

There is actually a logical explanation to these answers. Whenever faced with these types of problems, please check if the correct comparison is actually being done.
In 1:
(A) increased by more than twice
>> Ask the question "increased by more than twice OF WHAT ?"
There's no WHAT defined here, hence incorrect choice
(B) increased more than two times
>> increased more than two times OF WHAT ?
(C) more than doubled
>> more than double OF WHAT --- Answer of itself (So Correct)
(D) was more than doubled
>> "was" is not required, C is better
>> "had" is incorrect, there's no other event to compare to

Hence C

2.
(A) double the apples that it has
>> "has" is incorrect since there's no other event to compare to
(B) twice as many apples as it did
>> Answers the OF WHAT (twice of what it did in...) and no other error
(C) as much as twice the apples it has
>> "has" is grammatically incorrect
(D) two times as many apples as there were
>> incorrect parallelism "produces" v/s "were"
(E) a doubling of the apples that it did
>> doubling of apples is idiomatically incorrect

3.
(A) twice as much of its national output of goods as they had
US is singular, so "they" is incorrect
(B) double the amount of their national output of goods as they did
US is singular, so "they" is incorrect
(C) twice as much of its national output of goods as it did
twice as much OF WHAT ? >> "of its national output" :Correct
(D) double the amount of its national output of goods as it has
Usage of "has" is incorrect
(E) twice as much of their national output of goods as they had
US is singular, so "they" is incorrect

Hence C  Reply With Quote

Additional examples: My apartment is twice as big as Jim's - We have been here twice. Originally Posted by abhishek_jha There is actually a logical explanation to these answers. Whenever faced with these types of problems, please check if the correct comparison is actually being done.
