Hello,
Can you somebody help me understand why the Choice (C) is the correct answer and Choice (D) is wrong one? Regarding (C), I'm wondering why "more than doubled" can be used as a verb. Rather than (C), to me it is more appropriate to use "was" as verb and then to use "more than doubled".

OG SC #72
---------------------------
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.

(C) : more than doubled
(D) : was more than doubled
--------------------------

Best regards,

(C) : more than doubled
(D) : was more than doubled

C is better over D. In gemat, if we r talking about increase/double, double is prefered (i have read it some where) as verb. D is in passive form also, which is not correct. C correctly used doubled as verb.

(C) is correct. 'more than doubled' is all you need to complete the sentence.

In (D), the extra to be verb (was) is unnescessary. Removing it does not cause your sentence to be gramatically wrong, and it does not change the meaning of your sentence. We only use a to be verb + past participle when we deal with passive voice.

The construction is simple

Subject + predicate

The Number of Degrees (subject) doubled (verb) from 1978 to 1985.

The number of degree more than doubled from 1978 to 1985.
