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. :-)
Thanks.

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.

Experts please enlighten us.

I was confused between 'B' and 'D'. Finally chose 'B', which is not the answer :P

Hi Divyadisha and Nick90 as your Q is also related to the same,

Fisrtly there is no rule I have heard that now modifies elements ONLY afte rit..
it is very cold now...

As far as the choice B and D are concerned, I would say B is better to follow parallelism with the non-underlined portion..
generated through wind power now than it was in 1990...
so something NOW (time) as something IN 1990 (time)..
So B is correct

Hi sayantanc2k and sriamlan,

The first time I read it, I did not find anything wrong BUT then there was nothing wrong even in C..

so when I read it second time the choice B was slightly awkward..

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

what is slightly uncomfortable is what does IT stand for...
Logically IT should stand for ENERGY...
BUT energy is a part of NOUN phrase and IT should grammatically refer to the entire NOUN PHRASE...

C) more than ten times as much energy is generated through wind power now as was the case in 1990.
This corrects the pronoun issue, even if not in the best possible way..

I have read this somewhere earlier but others can pitch in..

Hi chetan2u, I see your point. But is it absolutely forbidden in GMAT that a pronoun has an antecedent within a noun phrase? Is this reason enough to eliminate an answer, especially when the other possible choice is not convincingly better?

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")

I don't know, I see a problem beyond the ones related above.

Quote:
as much energy is generated


Quote:
as it was ????? in 1990


"it" relates clearly to energy, BUT...

Quote:
as it was ????? in 1990


SO, replacing "it" by [the energy generated]..

Quote:
as [the energy generated] was in 1990


the point is that energy can't "be" anything, so we can eliminate B and D

now...

Quote:
as was the energy generated in 1990

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.

in B and D, doesn't 'it' refer to energy?
