(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.

(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

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

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".

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.

A) generated through wind power now than 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


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.
SJ

Just to summarize the understanding, "it" should refer to the "complete" subject along with the modifier.

Can I use "that"? Can you please clarify the difference.

Hi kinjiGC,

Any pronoun used to refer to a noun will include the associated modifier with it. It just cannot pick up the "noun" and leave alone the modifier. This is applicable for the use of "that" as well.

Hope this helps. :-)

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.

Hi,

Below was the explanation by Ron:

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'.)

Note:when a pronoun stands for a noun to which ESSENTIAL MODIFIERS (i.e., modifiers without commas) are attached, the pronoun must STAND FOR THE NOUN PLUS ALL ESSENTIAL MODIFIERS attached to the noun.

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.

There are two things that one can look into while solving this question.

1. as much as -> Correct idiom

2. Subject of the clause after the comma -> more than ten times as much energy
So it will refer to the whole subject, hence usage of it is incorrect

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 -> Correct
D) now generated through wind power as it was
E) now generated through wind power than was the case

Also if you assign a antecedent to a pronoun then you should be able to replace that pronoun by the noun. The sentence should make sense.

Let's try it..
more than ten times as much energy is generated through wind power now as energy was generated in 1990...
Does this make sense - NO It does not make sense...
If only we remove the energy the sentence makes complete sense.
But we don't have that option.
The next best option is C.

Hope this helps.

hi egmat


Can you explain why it is referring to 10 times the energy ?? Can we use that in place of it .

Please give some additional example on the same .

"It" does not refer to "ten times the energy" - a pronoun cannot refer to a group of words such as this one - a pronoun has to refer to a noun (or a noun phrase).

The point is that the pronoun "it" does not have any antecedent (nouns such "energy" or "wind power" are not suitable antecedents for the pronoun in this sentence). The proper antecedent of "it" could be the word "case", but this word is not there in the sentence. Hence all options that have "it" are wrong.

To answer your second question:
No, "that" is equally wrong - "that" as a demonstrative pronoun must have a noun to follow or as a relative pronoun must have a noun to refer to:

That pen is mine (demonstrative - the noun "pen" follows)
The car you have is bigger than that I have (relative - referring to "car").

However the following sentence is wrong:
There were many exciting games in the party: that was great.
(wrong - "that" cannot refer to the whole fact that "There were many exciting games in the party")
