Dear GMATGuruNY

Can you shed light on the question at hand? Why choices are wrong? is 'two times' and twice as...as' wrong?

The OA is unclear.

Thanks in advance


A rate is a MEASUREMENT.
A and B imply the following:
In the 1980's, the measurement...was...fast.
D implies the following:
In the 1980's, the measurement...was...faster.
The implied meanings are nonsensical: a MEASUREMENT cannot be FAST.
Eliminate A, B and D.

E: the rate...was...two times greater than the 1970's
Here, THE RATE Is illogically compared to THE 1970's.
Eliminate E.

Dear GMATGuruNY

How can I expressed that increase in one year was faster in other year?

An INCREASE -- like a rate -- is a measurement.
Since a measurement cannot be fast, it seems nonsensical to say that the increase was fast.
The following wording conveys a more logical meaning:
The population grew more quickly in 1980 than in 1970.

1970s NOT 1970's -> the 1970's is equivalent to "the rate in 1970s". This is very misleading and totally changes what the correct answer should be.

What is the role played by 'what' in the OA? Is it relative pronoun here? If so, two pronouns (what and it) simultaneously to refer a single noun (the rate of increase) seems unusual.


Consider the following sentence:

What was the population in 1970?
"What" is an interrogative pronoun (referring to a value that would come as an answer.)

Now replace the population with "it".
What was it in 1970?"
"What" remains an interrogative pronoun (referring to a value that would come as an answer.)
"It" refers to population.


In the same way, in option C "what" refers to the value, and "it" refers to "population".


Hi sayantanc2k,

Your explanation is great.

I have one query. Don't we need of before what in option C?

In the 1980's the rate of increase of the minority population of the United States was nearly twice of what it was in 1970's.

Thank you in advance.

Dear Friends,

Here is a detailed explanation to this question-

zoltan wrote:
In the 1980's the rate of increase of the minority population of the United States was nearly twice as fast as the 1970's.

(A) twice as fast as
(B) twice as fast as it was in
(C) twice what it was in
(D) two times faster than that of
(E) two times greater than


Choice A: In Option A, the term "fast" is used to refer to a rate of increase; as the rate at which something increases is not defined by speed, the usage of "fast" is unidiomatic. Moreover, this option compares the rate of increase in the 1980s to “the 1970s”, rather than the corresponding rate of increase in that decade. Thus, Option A is incorrect.

Choice B: Option B repeats the same error found in Option A, regarding the use of the word "fast". Thus, Option B is incorrect.

Choice C: Option C maintains proper idiom use throughout the sentence and conveys the intended meaning of the sentence. Thus, Option C is correct.

Choice D: Option D repeats the same error found in Options A and B, regarding the use of the word "fast". Thus, Option D is incorrect.

Choice E: Option E compares the rate of increase in the 1980s to “the 1970s”, rather than the corresponding rate of increase in that decade. Thus, Option E is incorrect.

Hence, C is the best answer choice.

All the best!

Hi All,

This prompt involves a comparison (the rate in one year vs. the rate in another year), so we need to the two 'pieces' of the prompt to be in 'parallel format.'

The sentence begins with the first half of the comparison:

"In the 1980's the rate of increase...."

Since the first half of the comparison uses the phrase "in the 1980s", the second half of the comparison must also follow that pattern: ".... in the 1970s." Eliminate Answers A, D and E.

With the remaining 2 answers, there's ultimately a 'usage' issue. A "rate of increase" in this context is not referring to something that is physically moving, so the usage of the word "fast" doesn't make sense. A rate can certainly be "twice" another rate though. Eliminate Answer B.

Final Answer:

GMAT assassins aren't born, they're made,
Rich
