why not B?

somewhere I read, GMAT considers "what it was" wordy.

Even I got this answer wrong few days back when I chose B. Though there is nothing grammatically wrong in B, but brevity is one parameter that GMAT looks for in the answer choices. Lets look at the Ans. choices 1 by 1.

A is unclear. 1970's also implies 1971,72,73 ..etc... which can not be compared to the rate of increase.
D: "of" is unparalleled. The correct choice has to be "In the 1980's ... In the 1970's ..."
E : Reject outrightly.

Now, out of B and C, C is correct choice because "the rate of increase was twice what it was.. .. " conveys the same meaning that "twice as fast as it was in...." does but in lesser words Hence C.

And the OA is C.
