Difficult to choose between B & C.
"rate of increase" and "as fast as" seems to be redundant. Use of "what" is correct.

A IMO
Just replace 1970's with "the rate of 1970" and you will get the answer as A.

(A) twice as fast as
- Correct as it is. Twice as fast as 1970's. It means that the rate was twice as fast as the rate of 1970. Clear in meaning.
(B) twice as fast as it was in
-- As it was in 1970's. It conveys that the rate was twice as it was in the rate of 1970.
(C) twice what it was in
-- Incorrect. Same reason as of B.
(D) two times faster than that of
-- Two times is not required because double is less wordy and appropriate to use here.
(E) two times greater than
-- Same reasoning as of D.

IMO D....

A not correct comparison.
B & C - it is not clear and very far from the rate
E - not correct comparison

RATE OF INCREASE has to be GRETER/LESSER/TWICE/THRICE...
IT CANNOT BE FASTER
SIMILARLY..RATE OF ASCENT HAS TO BE FASTER AND CANNOT BE GREATER...
SO ONLY C AND E QUALIFY AND SINCE E IS MISSING A PRONOUN PHRASE "THAT OF
" C WINS

here 1980s and 1970s are not possessive form so in should surely come so between B & C

will choose C

Twice/greater/two times..does'nt countable/non countable terms come into picture here??We are talking about "RATE" so should'nt we be using "two times" as apposed to "twice"??

rate of = speed / velocity. It is correct to say : X's rate of travel was faster than that of Y. rate of 4,5,6 can be faster than a rate of 2,3. Atleast that is what I think. Maybe I am being too scientific ,but if rate of means frequency or speed you can compare two rates(faster slower). What are your views on my assertion?

No need to have "fast" when we already have "rate of increase"

I agree ,but with rate of increase you can use faster - think of it in terms of velocity or frequency: X's velocity(rate of travel) is faster than that of Y(rate of travel/velocity). The same is true for frequency of occurrence. What are your thoughts?

the rate of increase can not be ‘fast’. It has to be ‘high’. ABD out. The rate can not be greater than the 1970’s(the years). Hence, C wins.

I guess the "rate of increase" shouldn't be fast, clear and consice and you could just use WHAT
