Because the population

by atulmangal » Fri Jun 03, 2011 10:31 am
Princeton Review:

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 than it is in an American city.


A. serving a given population is usually five times more efficient in a European city than it is in an American city

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 a European city than one serving a comparable population in an American city

D. in a 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 a European city will usually be five times more efficient than if it is implemented with a comparable population in an American city

IMO C

Because D violates the precision rule.

No need to repeat the bold words again.

Even i chose option C, but OA is option D

it can be because of the fact that D maintains that in both the places the system WILL be implemented in future. Whereas in C it compares future implementation of a system with a system that is currently present in american city.

any other explanation, Expert comments..

I think option C is wrong because initial part of the sentence talks about future with the usage of "will" and latter part talks about the present i.e "serving".............In D usage of "will" in both Initial and latter part of the sentence makes it parallel

IMO: D

We need a predicate verb here instead of "serving".

Because of X, Y ____. The blank needs to be an appropriate verb, so A and B can be eliminated.

Comparing the remaining choices, E is unnecessarily wordy.

C makes it seem like the the rail system is more efficient because it is IN a European city. D places the prepositional phrase "in a European city" directly after the noun it modifies.

Check out this similar question from the OG:

Because the earth's crust is more solid there and thus better able to transmit shock waves, an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern US than it does in the west.

B. of a given magnitude will typically devastate 100 times the area if it occurs in the eastern US instead of the west.

C. will typically devastate 100 times the area in the eastern US than one of comparable magnitude occuring in the west.

D. in the eastern US will typically devastate an area 100 times greater than will a quake of comparable magnitude occuring in the west.

E. that occurs in the eastern US will typically devastate 100 times more area than if it occurred with comparable magnitude in the west.

This question follows the same logic.

@Vivian : i eliminated C,D because they have future tense where original sentence is talking about present.

A has a verb "is".
Construction of A: "because..<modifier>,a commuter rail system(serving..modifier)is usually five times more efficient in a European city than it(commuter rail system)is in an American city"

so A becomes: a commuter rail system is usually five times more efficient in a European city than commuter rail system is in an American city"
C makes it seem like the the rail system is more efficient because it is IN a European city
Also i think this is what sentence is saying that rail system is more efficient in European City than in American city
Premise: If you like my post
Conclusion : Press the Thanks Button ;)

A. serving a given population is usually five times more efficient in a European city than it is in an American city

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 a European city than one serving a comparable population in an American city

E. that is implemented in a European city will usually be five times more efficient than if it is implemented with a comparable population in an American city
The stereo system in your room is bigger than it is in my room.

In the sentence above, the pronoun it is incorrect. One stereo system cannot be in two rooms at the same time.

For this reason, eliminate A and B in the SC above. The pronoun it implies that one rail system can be in two places at once.

In E, implemented in is not parallel with implemented with. Eliminate E.

In C, the placement of in a European city next to efficient incorrectly implies that the location of the rail system is why the rail system is efficient. Eliminate C.

The correct answer is D.

Is it because "it" refers to exactly same entity and not a similar/generic entity at another place, Please comment if following sentences are correct.
The stereo system in your room is bigger than the stereo system in my room.
The stereo system in your room is bigger than that in my room.
In C, the placement of in a European city next to efficient incorrectly implies that the location of the rail system is why the rail system is efficient. Eliminate C.
Can you please explain how you got this meaning.
