Hi Abhishek009 and souvik101990

Would you kindly present your analysis of the sentence? Why D is correct and other choices are wrong?

I have a doubt about D. It essentially says: A system will be more efficient than will a system. Doesn't it require a 'be' in the second part too, in order to maintain parallelism?

Pls reply. Thanks.

IMHO (D)


i have a doubt regarding D option it says "the system" now this system can be commuter rail or any other system also....

I take the opportunity of stating my bit , daring to do so , however undoubtedly the OE and the best reply will surely be provided by souvik101990

Here the meaning of the sentence is clear it Compares -
Quote:
the efficiency of the commuter rail system of an a European city with the efficiency of the commuter rail system of an American city


In (D) we are comparing-

The commuter rail system in a European city with the commuter rail system in an American city

Further the choice (D) has the following issues -

1. Parallelism : in a European city ............. in an American city

2. Comparison : more .........than.........


So IMHO (D), souvik101990 awaiting your Official explanation...

The Right Answer is (D)
Because in parallelism, when we omit repetitive words , if verb in the first part appear with a helping verb then , in the second part of the sentence only first portion of the helping verb will remain and rest will be omitted

Is it not changing the meaning of the sentence to introduce the whole "comparable population" clause? Since the size of the cities is not mentioned at all in the original sentence?

Halo secterp,

Let me try to answer your query. :)

Please notice that in the original sentence we have a phrase serving a given population , which implies that rail systems for equivalent population have been compared between 2 different places. Therefore, comparable population in option D does not change the meaning of the original sentence.

Does the above clarify your doubt?

This post was
BOOKMARKED
this question tests parallelism and comparisons. 'than' is a parallel marker.

A - the problem is with the word 'it'. It/they/them/their refer to the same copy, whereas those/that refer to a different copy. Another thing to remember is 'it' refers to the noun with all its modifiers. This option thus absurdly implies that the same commuter system is more efficient when it is used in Europe.
B - Let us rewrite this option - if the commuter system is placed in a European city instead of an American city, the commuter rail system will usually be five times more efficient. this is absurd. We cannot transfer the commuter system across continents.
C - This option compares "a commuter rail system" with "commuter rail system serving a comparable population in an American city" - Not parallel. We need to compare the commuter rail system in Europe to commuter rail system in US. Also, "a commuter rail system will usually be five times more efficient in a European city" implies that if we transfer a commuter system to Europe, it becomes more efficient.
D - correct answer. correct comparison between - 'a commuter rail system in a European city' and 'a system serving a comparable population in an American city'.
E - 'it' has the same problem as mentioned in A. 'if it is implemented ...' is also not parallel.

Hey CrackVerbalGMAT,

Can you please elaborate a little on--- "It/they/them/their refer to the same copy, whereas those/that refer to a different copy. Another thing to remember is 'it' refers to the noun with all its modifiers." It will be very helpful for me.

Also another question on option C.

When we are comparing 2 nouns say X and Y then modifiers cannot be considered?

As in C : a commuter rail system WITH commuter rail system serving a comparable population in an America

Thanks!

Bitan

My goodness this one took me 3:30 to answer. I ended up getting D based off logic of the sentence rather than grammatical issues. Does anyone have a progression system that they use to help with time constraint? It took me too long to realize that this could be solved using logic instead of grammar.

What's wrong with A folks? When we are talking about these systems, we may be talking about them in a matter of fact tone - in that case simple present should be used and A can be correct. Thoughts please.

I do not see a problem with option C.

However, the usage "five times more" is generally not correct. If the intended meaning is y= 5x, then the correct construction would be "y is 5 times x" - not "y is 5 times more than x".

And we do have the same construction in the correct option D as well

in a European city will usually be five times more efficient than will a system serving a comparable population in an American city

Is my thought process correct if I just look for the answer choice that has a "In a European City" closest to the start of the answer choice. I am doing so because the first part of the sentence is a modifier(?) that is modifying "A European City". So the answer choice has to be the one with the European City closest to the beginning.

This was just my 2 cents...

Also (as you can tell) I'm new to the forum. Are the verbal and math questions of the day - devised from GMAT Club Forum users, so anyone can create a question of the day? If not, who/where are the questions and answers coming from?

I'm noticing a surprising trend that a lot of the Quant questions test inane/slightly obscure concepts, but the Verbal questions are slightly more reasonable, yet still have a rough edge to them...

(could just be me tho)

The first part is not a modifier, but a dependent clause starting with "because". Hence the position of "in European city" is not critical to answer this question.

Your other queries about the questions of the day will be replied to shortly.
