Energy in a. B refers to expenditure but should refer to energy.

A = redundancy with the word expended

I like b.

A it is.

The complete sentence should read:
"The energy expended per unit of production in the United States is as much as twice the energy expended per unit of production in West Germany."


In A, "the energy" is replaced by "that". "per unit of production" is understood and omitted.

energy expended per unit of production in the United States is ______ . Since it is a case of parallel construction it is essential to use energy expended or a pronoun in its place. Hence I feel the choices with the word expenditure should be avoided at best. Which rules out B, C and E. Amongst A & D - A sounds perfect. My logic worked fine for me.Hope it is the correct approach though!

comparing A and B ....B is wordier ...in A it is already implied that this energy is from the expenditure ....so explicitly mentioning it in B is redundant

(A) as much as twice that expended in West Germany
(B) as much as twice that of West Germany’s expenditure

what is the difference between option A and B?. the phrase 'that' refers to which one in bothe sentences


expended in the United States... ... expended in West Germany
expended in the United States... ... of West Germany's expenditure

Option B is not so parallel as option A. You see that in A "expended" is acting as a verb, while in B "expenditure" is a noun.

Option B is not so parallel as option A. You see that in A "expended" is acting as a verb, while in B "expenditure" is a noun.


In A, ask yourself the question: what is expended in the US? the answer is "energy". But that works only because the phrases are parallel:
the energy expended in the United States is as much as twice that expended in West Germany

If we don't have "expended" in the second phrase, then it is not so clear what is "that" referring to. And that is the problem, because we have instead "that of West Germany's expenditure". Even when you can understand the sentence, and guess what "that" is referring to, the option A does it in a much clearer way, and that is preferred in the GMAT.

choice a is wrong because (see "born to women over 30 years old" from gmatprep)
the part you keep after ellipsis should be the same as the previous part

there is no"expended in " in the first half. there is only "expended per" in the first half. in other words, you can not cut off a phrase which is not continuous.

D is best

I want to talk more of this problem though it is not official one

the rule of ellipsis is that
- the cut off part must be present in the previous part
- the remaining part must be paralel to a phrase in the previous part so that it is clear in meaning or the remaining part must be clear in meaning but dose not need to be parallel. we need a parallelism here to make a clear meaning. of course, if both choices are clear in meaning, the choice which is parallel is possiblly considered better.


in b,c and e, energy is compared to expenditure. this is not logic

the problem in a is that a dose not meet the the 2nd standard above. the remaing part is not parallel to a phrase somewhere. there is no "expended in the us" . moreover, "expended in germany" is not clear in meaning. so this phrase is not correct.

even choice D is not clear in meaning. "what" is not clearly energy.

this question is not good. it is presented for us to discuss about comparison and ellipsis.
