Concept tested:

Ididom : -- As...X...as

As "Much" energy is generated through wind power now AS
.....

A ,E - out of wrong IDIOM
B,C and D use correct idiom.

Much :- modifying generated Energy, so we need something like

as much energy is generated through power now as energy was generated through power in 1990.

Now see what match near to this:-
B) generated through wind power now as it was

it :- refer to Energy
as much generated through wind power now as energy was in 1990.

compare total energy in 1990 , with currenty generated energy using wind power.

C) generated through wind power now as was the case

was the case :- energy generated using wind power in 1990.. correct comparison here.

D) same problem as that of B

IMO: C

ah. a clever question. clever mostly because it contains BOTH "more than" AND "as much as", requiring you to put in some extra effort to distinguish between the two.

fortunately, the "more than" is sitting there in one piece, so you can basically just ignore it and pretend that the sentence just says "ten times as much...".

with "as much", you need "as", not "than". so (a) and (e) are dead.

--


in any case, the choices with "it" are incorrect because the "it" doesn't have a legitimate antecedent.
pronouns automatically stand for nouns plus all the adjectives and essential modifiers that are attached to those nouns. therefore, "it", in this sentence, would have to stand for "more than ten times as much energy". that, of course, doesn't work.

by the way

here's the most important takeaway from this problem:

if you see a split between
* a PRONOUN
and one of the following two:
* a specific noun;
* an abstract expression that's meant to substitute for a pronoun (such as "was the case" or "do so");

then you should be HIGHLY suspicious of the pronoun.

so, if you see "do so" vs. "do it", you should bank on "do so", unless you have VERY strong reasons to go the other way.
if you see "them" vs. "those NOUNs", you should bank on the latter, unless you have very strong reasons to go the other way.

same here.

if we use "was the case", "the case" is compared with "energy". This is incorrect

This is another trap that GMAT tests often.

In OG 10, there is a question about comparing the effects of earthquake wrt west n east coasts.

The concept tested is this: you have a comparative adjective modifying a noun; this noun phrase ( comp. Adj + noun) is referred to as "it" in the "as clause".

Thank you Ron. It is wonderful to have you in this forum.

I have a question.

I see in many questions in OG, "that" can refer to only one word, a noun, not to a noun+modifier. "that" is a pronoun so I think "that" is a special.

Ron, Can you explain more about "that"

Received a PM asking me to respond on how "energy" can be compared to "case."

"as was the case" is actually referring back to the first item in the comparison:

energy generated now
vs
energy generated in 1990

because they tell us that it's 10x now, we could also interpret this as:

10x energy generated now
vs
x energy generated in 1990

The reason we can't use "it" to refer to "x energy generated" is because "it" is a pronoun and can refer only to nouns. We're trying to refer to an entire clause (includes the verb "is generated"), so we can't use a simple pronoun. "was the case" is more flexible - that can actually refer to the whole clause, not just a noun.
Please note: I do not use the Private Messaging system! I will not see any PMs that you send to me!!
