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)



I don't want to imply anything but the quant questions are tricky questions from the GMAT Club tests. They are designed to test your knowledge, not make you feel comfy. These are 700+ level questions, so they tend to be unusual - often something you have not encountered before and something that requires you to think out of the box.

I am confused with A. It seems that A has pronoun problem. But I think IT can refer to the commuter rail system. Can anyone please give a proper explanation?

As per my opinion....

Because the population is denser there and the auto mobile 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 : no clear antecedent of "it"

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: idiom error.

c will usually be five times more efficient in a European city than one serving a comparable population in an American city: "one" is ambiguous.

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

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 : no clear antecedent of "it"

Hi,

D straight way wins because rest choices talk as if it is the same commuter rail system that is placed at both places..

But we are comparing the system in place A with system in place B..

Now about future tense..
There is nothing wrong here. You are talking of effect of some activities if done in future.
Example- he will win the game because he is a better player.

Hi chetan2u and all,
I am confuse with the additional word "comparable" in the correct choice. Does this change the meaning?
Also,I don't see anything wrong to compare the existing rail systems in option A.

In my 2 cents,option A says that the current population in EC is denser than in AC;hence the rail system in EC is more efficient than that in AC.
On the other hand,option D says that the current population in EC is denser than in AC;hence the rail system in EC will usually be more efficient than that serving a comparable population in AC.

Hi,

A uses 'given population' so here given works the same way as comparable....
Otherwise it would be just 'its population'.

Example :- in the given scenario, country x will emerge stronger than country y..

But A has a problem in comparison of commuter rail system.

In my opinion, options C and D both are gramatically alright. C may be considered better because of concision.

Option A may be considered wrong because it appears that the same rail system serves both a European city and an American City (because of the usage of pronoun "it").
Option B is wrong also because of the same reason as above. Moreover there is no "than" corresponding to the comparative adjective "more".
Option E is wrong because of the same problem as described for A.

The OA (i.e. the "official answer") is the one that the author decides. Though in my opinion, both C and D are gramatically correct (and C is slightly better than D because of concision), the OA is still D.
