I chose C after quickly eliminating A and B. C is grammatically correct and concise.

Definitely C.

Rate cannot be faster or slower as indicated in choices A and B.

E.g.: Smith's height is tall doesn't make any sense. Similarl is the case with "xyz's rate is faster".

C) since rate cannot be "fast".

1) as...as... creates a comparison.The first as is followed by an adjective or adverb. The second as is followed by a noun, a phrase, or even a whole claue.
2)Correct idiom is twice as fast as.
3) To relate quantities by multiplication, use times and as...as...together.

I think the correct answer is B.

Rate of increase can be faster or slower relative to another number.

As an example, if you substitute faster for slower it could say:

In the 1980's the rate of increase of the minority population of the U.S. was nearly twice as slow as it was in the 1970's. (1970's rate was 50%, 1980's rate was 25% - rate is slower, but still an increase)

As many people correctly pointed out, B tries to modify the noun "rate" as "fast", making the sentence illogical.

In addition, B uses the pronoun "it" incorrectly. The pronoun "it" must refer to the SAME "copy" of thing. For example:

-Mike saw a scrumptious piece of cherry pie at the shop. The temptation was too great, and he had to eat it.

Here, "it" refers to the same piece of cherry pie, Mike had seen earlier.

"it" in B refers to the same rate of increase that appears in the sentence earlier. Of course, this is incorrect, as the purpose is to compare two DIFFERENT rates.

Hope this helps!

C is the best one here.

In spite of using "what it" (uncommon terminology), C seems to win by POE.

Rate can't be faster or slower. Therefore, C is the best answer.

Got it wrong - Picked B (Correct ans is C)
'Rate of increase' already indicates the speed. Adding 'as fast as' makes it redundent.

Thanks.

Picked C

Rate can't be faster - rate is usually higher or lower

A: rate of increase twice as fast as 1970 - makes no sense if taken literally i.e. rate can't be as fast as "1970
B: rate being fast issue
C: rate... twice what it was in... (correct comparison)
D: rate being fast issue
E: double comparison "2 times" & "greater"

I choose B but I see why C is the answer. Bottom line is I got sucked into the long prepositional phrase. GMAT tries to disguise the subject even in this idiom question. You have to anticipate that the sentence is trying to throw you off. If you isolate the subject and remove the fluff, its easier to see what is being compared. Here is the original sentence marked up to show the bare bones of the sentence. Both A & B suffer from the similar problem.

In the 1980’s the rate of increase of the minority population of the United Stateswas nearly twice as fast as the 1970’s. (the rate can't be fast or slow, the rate just is) Just add a number before rate, say 10%.

In the 1980’s the 10% rate of increase of the minority population of the United Stateswas nearly twice as fast as the 1970’s. (it doesn't make sense. A 10% rate is twice as fast?)

Here is the correct sentence with a number added.
In the 1980’s the 10% rate of increase of the minority population of the United Stateswas nearly twice what it (with it referring to the rate of the 1970s) was in the 1970’s.

first of all, we are comparing the rate of increase in 1980 to the rate of increase in the 1970.
since we are comparing the same thing, and since we have a preposition "in" at the beginning of the sentence, there is a high probability that the one specifying "in the 1970's" is the right answer.
moreover, A is incorrect, "as fast as" means the same, thus, it can't be twice!!! as fast.

(A) twice as fast as
twice + as fast as - is awkward and incorrect. as fast as means the same.
(B) twice as fast as it was in
same as in A. twice as fast as - incorrect. nevertheless, the it was in is ok.
(C) twice what it was in
looks good, it says that the rate in the 1980 was twice what it was in 1970.
(D) two times faster than that of
two times faster - wordy, moreover, it changes the meaning as it says the rate of 1970, not the rate of of increase of the minority population. than that - implies as smth else is compared, although the only antecedent for "that" is the rate.
(E) two times greater than
greater is used for comparing 2 different things. thus it is incorrect.
