your logic of not using 'it' for comparision when compare one thing to another does not fits here.

Can you please throw some flashlight here ?

404. 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


C is right 'it' is ok as referring to the old copy which was in a different state in the past. Twice is better than two times. Also I feel 'as fast as' is a repetition of rate of increase according to logic.
eg- My tummy has grown bigger to what it was a decade ago. (single objects)
eg- My tummy has grown bigger than that of my neighbor's. (two diff objects)

On the older (the one posted on the top) question, I believe x2suresh makes more sense. 'SaraiGMAXonline' logic is of no use there.
eg- I love the cake as it is brown in color. (right)
eg- I love the topping on the cake as it is brown in color. (wrong: Pronoun ambiguity)

Please comment.

Let me see if I can clarify. In the problem above, the rate is indeed compared to itself, and thus, "it" is appropriate. Also, you are right yogeshagarwala, "two times" is never correct on the SC.

As for the "I love cake..." example, that sentence is not a comparison, so the correctness of "it" is a matter of ambiguity, a matter completely separate from the issue of "it" versus "that" in comparisons.

the moment we realise that we must use the expression "as X as Y" remaining choices can be eliminated quickly.

A can immediately be ruled out because it uses THAN --- even if we disregard the ambiguity caused by IT.
Choice B uses correct idiom and now we cannot disregard the ambiguity caused by IT.
same problem as in B exists with D as well.
E uses THAN so again it can be eliminated. only choice remaining is C.

Please comment on the use of 'it'. I believe its an issue with pronoun ambiguity for B and D.

Well ..
'it' is a pronoun .. and it can only be used to refer a noun .. now in the meaning of the sentence, it is used to refer energy generated not the energy itself - the focus is on generation of energy in two times. Hence, we should not use 'it'.

Comment ?

To compare something to itself, use "it" or "they".
Ex. The legs of chair A are more wobbly than they were yesterday.

To compare one thing to another, use "that" or "those".
Ex. The legs of chair A are more wobbly than those of chair B.

Thus, in the problem above, using "it" would mean that you are comparing some amount of energy to itself. But we want to compare one amount of energy to another.

The correct idiom is "as X as Y"
that leaves B, C & D

There are hopeful signs that we are shifting away from our heavy reliance on fosil fuels; more than ten times as much energy is generated through wind power now than it was in 1990.

A generated through wind power now than it was
B. generated through wind power now as it was - 'it' can refer to 'wind power' or 'energy'
C. generated through wind power now as was the case
D. now generated through wind power as it was - 'it' can refer to 'wind power' or 'energy'
E. now generated through wind power than was the case

The real comparison is between the energy produced now and the energy produced in 1990. The expression - ten times as much energy as -is the term used to describe the quantum of energy.


A) more than ten times as much energy is generated through wind power now than it was
B) more than ten times as much energy is generated through wind power now as it was
C) more than ten times as much energy is generated through wind power now as was the case
D) more than ten times as much energy is now generated through wind power as it was
E) more than ten times as much energy is now generated through wind power than was the case

You may see that A and E, use a wrong idiom namely 'as much energy than' and hence can be safely dropped. Among BCD, B and D lose steam because of using the pronoun"it' without a clear referent.

C is therefore the right royal choice.

There are two idioms coming into play here... 'more than X' and 'X as much as Y'

The second idiom requires an 'as much as' construction so A/E are ruled out.

In B/D, "it" has no logical antecedent...
Ans is C.

C sounds the correct answer because of the idiom as much as. Moreover, you have to consider the position of the word "now" in the phrase. When "now" is used in front of the phrase "generated through windpower...", it changes the meaning of the sentence as it implies that the wind power is being generated "right now" as we speak where as the author intended to mean the general sense here.
C correctly uses the position of "now" to preserve the meaning of the sentence.

1.'More than ten times' is just an expression of quantity and not a comparator. The comparator is actually the positive degree ‘as much’. Now when the un-underlined portion contains ‘as much’ for the comparison, then you must idiomatically complete the comparison with another ‘as’. This means, we have to stay put with choices B, C and D, dropping A and E.

2.We must not misconstrue that the pronoun ‘it’ stands for just energy, The pronoun stands for the entire antecedent that goes to describe the energy namely ‘more than ten times as much energy’; Therefore the use of the pronoun ‘it’ doesn’t make much structural sense. We have to drop choices B and D on that count. We must admit C as the most fitting, though a bit unusual to the ears.

Incidentally a colon is no more than a kind of parenthesis. The things that follow the colon must represent the idea that is expressed prior to the colon, in this case ‘hopeful signs that we are shifting away from our heavy reliance on fossil fuels;

C) generated through wind power now as was the case
D) now generated through wind power as it was
E) now generated through wind power than was the case



Answer is (C)

Option B is incorrect coz of its use of "it". "it" must refer back to the entire noun phrase i.e. more than ten times as much energy BUT not just energy. Hence incorrect.

correct answer choice should not have 'than' because that is already there in the non-underlined part of the sentence,
more than ten times as much energy
so the idiom which remains here to consider is 'as much as'.

So out of B & C (eliminating D because of wrong placement 'now'), I had chosen B, however if I try to justify official answer, than it would be just because of the GMAT SC thumb rule ' Avoid it because most of the time it creates ambiguity'

A) more than ten times as much energy is generated through wind power now than it was

B) more than ten times as much energy is generated through wind power now as it was
C) more than ten times as much energy is generated through wind power now as was the case
D) more than ten times as much energy is now generated through wind power as it was
E) more than ten times as much energy is now generated through wind power than was the case

You may see that except A and E, others do not use the right combination of idiom- more x than y -
By using the pronoun it, the antecedence of which is not clear, whether it is energy or wind power, A loses steam.

E is therefore the right royal choice.
