Because the population is denser there and the automobile is therefore inefficient as a means of transportation, a conmuter rail system serving a given population is usually five times more efficient in a European city that it is in an American city.

A idem
B serving a given population will usually be five times more efficient if it is placed in a European city instead of an American city
C will usually be five times more efficient in an European city than one serving a comparable population in an American city
D in an European city will usually be five times more efficient than will a system serving a comparable population in an American city
E that is implemented in an European city will usually be five times more efficient that if it is implemented with a comparable population in an American city

yo puse la tercera pero la respuesta es la cuarta

Thanks

Good Q

I think its C

Because the population is denser there and the automobile is therefore inefficient as a means of transportation, a commuter rail system serving a given population is usually five times more efficient in a European city that it is in an American city.
A idem
B serving a given population will usually be five times more efficient if it is placed in a European city instead of an American city
C will usually be five times more efficient in an European city than one(commuter rail system )serving a comparable population in an American city

The answer according to me is D.
If we see the word 'there' in the first clause clearly indicate that it is a pronoun here and hence needs a noun.
Thus the clause following the first clause should immediately introduce some noun which is "European city" here.
Also we should remember a sentence that has modifiers placed as close as possible to the object it is modifying is always the best choice. Hence correct sentence should read commuter system in Eu city. However we will go by POE.
A-- says that "commuter system that is serving a given population is 5 times more efficient". But we are talking of any commuter system not a specific one.Hence A is out of league.
E--out becasue uses 'if' after 'than'. We are comparing and we dont need conditions here.
B-- same reasoning as A.
Between C and D, D seems better to me becuase C compares commuter system with a city.
D is best becuase it places European city as close as possible. secondly the structure is better:

a conmuter rail system in X will be five times more efficient than will a system serving in Z-- here comparsion correctly between commuter system serving in two countries...

I don't know how much sense it makes...it took me 20 mins to post this reply... .

C and D are close, but am not too sure which one. Do you have OE as well? What's the source of this question?

C has parallelism problem

D is clear in the comparison.

I also chose C on the first instance, and only after seeing OA analysed the issue once again

B serving a given population will usually be five times more efficient if it is placed in a European city instead of an American city
C will usually be five times more efficient in an European city than one serving a comparable population in an American city ( More than is used as compartive conj and sentence should have repetion of verb or prepostion) In this case will is missing in second part of sentence)
D in an European city will usually be five times more efficient than will a system serving a comparable population in an American city ( In this case 'will' is used, but inverted construction causes confusion, and make it less promising. This is the best answer)
E that is implemented in an European city will usually be five times more efficient that if it is implemented with a comparable population in an American city
