There are hopeful signs that we are shifting away from our heavy reliance on fossil 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

(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.

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.

Why do u say that "it" is ambiguous? For me is clearly referring to energy.


A tip regarding comparisons!

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.

Obviously between B and D....
I think there is no suprise to you :)

I choose D...

Clearly expresses the meaning of a sentence. 10 times as much energy is now generated through wind power as it was generated some time ago....

The other option B, has a different meaning.... 10 times as much energy generated through wind power....meaning the use of wind power has not necessarily increased....

A very good SC....

For the comparison, "than' has to be there. So, only A and E remain.
I feel A should be the ans.
The change of placement of 'now' changes in the meaning in E - emphasis seems to shift from comparison between period to the source of energy.
Though 'it' needs to be watched carefully, it seems to be correctly referring in A.
What is the OA?

Very difficult question, in my opinion. There's obviously a split between as/than, which usually means you go find either "as adjective (as)" or "comparative adjective (than)" to match elsewhere in the sentence. But this sentence has more (already with another than?? Would a than in the choice be redundant?) and ten times as much (do we need another as in the answer to complete this??) And then there's the issue of meaning. If I were to paraphrase, I use more than: Hopeful signs means...more energy generated by wind now than before.

I had to make up a similar sentence to help myself.

(More than) (ten times as many) people are living in urban areas now than were (living in urban areas) in 1900.

The phrases in parentheses ultimately modify people: More people.
The than/10x as many just quantify how much more.

With that complexity removed:
More people are living in urban areas now than were (living in urban areas) in 1900.

We need than in the choice, so we can focus on A and E.

(A) equates to: More people are living in urban areas now than they were in 1900.
(E) equates to: More people are living in urban areas now than was the case in 1900.

Which would you choose?

Thanks in advance.


Yikes - tough question. I think this is likely to be a parallelism issue. Answer choices B, C and D makes the sentence parallel as follows:

...more than ten times as much energy is generated through wind power now as ...

B and D use the phrase 'as it was' - it is unclear what 'it' is referring to in the context of the sentence, so eliminate these choices and go with C.

See, I told you I had trouble with it! :)

So if it is C, then it must be that as in the choice matches up with (i.e. completes) the as much in the non-underlined portion.

Basic comparison is then "as much energy is generated now as was (generated) in 1990."
I guess "more than ten times" modifies the whole comparison.

Maybe I should have viewed my other example this way (note that I have moved the paretheses)
(More than ten times) (as many people are living in urban areas now as were (living in urban areas) in 1900).

Maybe the clue should have been that for every than, there would have to be a more. (C) has 2 than's and only 1 more.

Good point. A has this flaw, too. Our final take-away probably should be to start with this less controversial split, and only then make the choice between C and E based on as/than.

@SaraiGMAXonline

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.

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;

I remember this question in the past when I faced it in the SC1000. I chose this one because choice B and D, "it" refer to no antecedent. After that, I also found in manhattan forum that contain this problem. Here is the topic discussing about this problem and Ron Purewal's explanation:

Quote:
i could've sworn this problem was in another thread, but the search box won't find it.

there are two splits you should use to narrow down this problem:

(1) the second half of the construction 'ten times as much ... ____' is as, not than. therefore, you can eliminate answers (a) and (e), which contain 'than'. (i'm assuming that (e) is supposed to say 'than', not 'then'; i don't think the gmat problems would that blatant an error)

(2) the pronoun 'it' is inappropriate, because 'it' must refer to the ENTIRETY of the noun phrase serving as an antecedent.
for instance, the following is an improper sentence: last year's attendance was ten thousand greater than it was this year
in the above sentence, the pronoun 'it' must necessarily refer to last year's attendance, not just attendance.
the problem in this post has the same issue: the pronoun 'it' must refer to more than ten times as much energy, not just energy - an interpretation that makes no logical sense. therefore, all answer choices containing the pronoun 'it' are wrong.

if you don't like '...than was the case', you should learn to like it; this is one of those phrases that the gmat writers use to refer to concepts that don't fit under the usage constraints of traditional pronouns. (another popular one of these constructions is 'do so'.)
