(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

"B" or "C". Think I will go with "C" as it's concise.

Can someone elighten me what's the difference between "two", "twice" and "doubled", and when to use these variations?

"

twice" means "two times"; for example:

I play tennis twice a week. (This means that two days in a week you play tennis. Let's say Monday and Friday)

"

double" means to become two times multiplied in amount; for example:

The number of the houses in this city has doubled. ( This means that if there were 100 houses before, now there are 200 houses.)

In this question :

The number of undergraduate degrees in engineering awarded by colleges and universities in the United States

increased by more than twice from 1978 to 1985.

if we use "twice", it means that the number increased two times from 1978 to 1985. (Let's say once in 1979 and another time in 1982). However, we want to say that the amount is multiplied by two.
