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.

PS: This post has been edited by me reflecting the points noted by another poster.

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



idiom: as much ..as

it --> ambiguous..
it can refer to energy/wind power ..
A,B --out

C is perfect and parallel.

ten times as much "energy is generated...." now than as was the case<energy generated .. through wind pwoer.> in 1990


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.

(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

I chose E,but the answer is C according to GMAT pill(GMAT Practice Test Set # 14 (Question 40-42)).I chose E as there was no misleading it and the comparison was clear.Can somebody explain why C is the answer and not E?


The correct idiom is "as much as". So A and E can be eliminated at the first instance.
Having our eyes on BCD, we eliminate B and D in that there is no clear referent for it. If you are think that "it" refers to "energy" , then try doing so.
B) generated through windpower now as "energy" was in 1990
D) now generated through windpower as "energy" was in 1990.

+1 C
Hope that helps.

Quote:
A.) generated through wind power now than it was

Wrong use of the idiom "as much as".
Quote:
B). generated through wind power now as it was

Wrong, because the "as" is followed by a subject pronoun "it". Putting a noun after "as" is confusing by suggesting functional comparison or by turning the "as" into the subordinating conjuntor; here with the possible meaning of "because". For more about that aspect of using "as" see: Manhattan SC, p. 144.
Quote:
C). generated through wind power now as was the case

Correct, because the verb "was" after the "as" eliminates the confusion described under B). Correct idiom form is used too. One may suspect wordiness here, but the sentence is very clear, isn't it? I seldom go for patterns in 700+ problems.
Quote:
D). now generated through wind power as it was

Wrong for the same reason as B).
Quote:
E). now generated through wind power than was the case.

Incorrect use of the idiom "as much as".

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


Meaning : There are hopeful signs that we are shifting away from reliance on fossil fuels.More than ten times as much energy is generated through X as it was generated through wind power in 1990.

There are two idioms tested.
as X as Y and X more than Y.

A) generated through wind power now than it was
as much X as Y -> We require "as"

B) generated through wind power now as it was
-Confused as to why B is wrong

C) generated through wind power now as was the case
- Looks good.

D) now generated through wind power as it was
- couldn't eliminate on solid grounds

E) now generated through wind power than was the case
As much X as Y

Can you please explain what can be the error in B) and D). Why "as it was" is wrong. I think if we ellipse on this.

more than ten times as much energy is generated through Wind power now as it was generated through wind power in 1990 -> Looks correct to me.


Hi kinjiGC,

Thanks for posting your doubt here. :-)

So basically why "as it was..." is incorrect in the context of this sentence. It is so because "it" refers to "more than ten times as much energy". It is so because in such constructions, the modifiers related to a referent noun CANNOT be left alone. So in Choices B and D. This obviously does not make sense as this reference leads to illogical comparison.

However, Choice C, this is not the case because "as was the case" refers to generation of energy in 1990.

Hope this helps. :-)
Thanks.

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'.)

source: brutal SC's


A few things are quite clear here : Two comparators "more than" and "as much as" and both should be complete. It is clear "more ..than" is complete in non-underline part, so part of "as" of "as much" is what we are looking for. So option A & E is out.

Out of B C D, pronoun it is referring to noun "energy" while what we are interested is in "amount of energy" so B And D out too. We are left with C and the OA

Why B is wrong and C is right? Can anyone please explain with details?


I do not see a problem with B. Probably other experts could provide their opinions. To me the parallelism seems OK in B:

...more than ten times as much energy is generated through wind power now as it was (generated though wind power) in 1990.

The blue and pink highlighted portions seem to me parallel; moreover it is allowed to omit repeated (even verbs) from the second parallel element.

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;

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?

Hi esledge,
Indeed a very nice explanation. But the OA is C. Could you please justify?
Thanks

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.

carriedinterest wrote:
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.

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.

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.

(A) generated through wind power now than it was it refers to wind energy + correct idiom is As much as

(B) generated through wind power now as it was --- it refers to wind energy

(C) generated through wind power now as was the case

(D) now generated through wind power as it was it refers to wind energy

(E) now generated through wind power than was the case correct idiom is As much as

one tip here:
AS is the case, As was the case - refers to a situation and is correct usage
As with the case - sure shot wrong option

Let us replace "more than ten times" with eleven times.

The sentence fragment now reads: Eleven times as much energy is generated through wind power now ...

"As much energy" needs "as" to complete it, as otherwise one is not sure how much energy was actually generated. So A and E are out.

Now notice that B and D differ only in the placement of "now". Although ideally the adverb should follow the verb, the rules are not strict. So you could eliminate both B and D, as the GMAT cannot have two correct answers.
B would be preferred as its construction is parallel with the last part of the sentence.

But, B and D have another issue. Both use the ambiguous "it".
One way to disambiguate this construction would be to reorganise the sentence:
Eleven times as much energy (as was generated in 1990 through wind power) is generated through wind power now.
"It" cannot be used to refer to the entire expression in parentheses.

So the answer must be C.
