Long-distance travel for humans primarily relied on animal power until 1829, when the steam locomotive was invented by Richard Trevithick, who had found a way to provide sufficient traction for movement and led to the building of locomotive-driven passenger trains.

Experts, please share your view. Even I am not clear on this so not putting any explanation about how did I arrive to a particular choice. Guess work might mislead other friends.

rphardu,

This one seems tricky, but fairly straightforward once you grasp the meaning. In its current form the sentence seems that Richard Trevithick led to the building of the locomotives. It should in fact be his discovery that led to the building of the locomotives. You can immediately eliminate A, B, C and E.

D is the correct choice. Keep in mind that the sentence structure is constructed in a way that best expresses (and optimally) the meaning of the sentence.

Hope this helps you.

Pause a moment and read the question -
Long distance travel - when steam locomotive was invented by Richard Trevithick - a way to provide sufficient traction for movement and led to the building of locomotive-driven passenger trains

How can these actions be chronological - 1 possible answer - if WHOSE is used to describe the way that provides traction and led to the building of locomo....

I can see the choice D has this sequence and no grammar errors - Choose and move ON

If you have time you can eliminate the other choices .
A-Long-distance travel for humans primarily relied on animal power until 1829, when the steam locomotive was invented by Richard Trevithick, who had found a way to provide sufficient traction for movement and led to the building of locomotive-driven passenger trains

Break it up and read - Richard Trevithick cannot lead to the building -- Nonsense

B- same error as in A --Nonsense
C- Richard cannot lead to the building of locomotive-driven passenger trains --Nonsense
E- Again Richard led to the building of locos --Nonsense

+1 D. Richard Trevithick didn't led to the building of the locomotive, but rather his discover did. All other choices seem to indicate Richard Trevithick led to the building of the locomotive.

Because Richard didn't lead to the building of locomotive trains but it was his discovery that led to the building of locomotive trains.

Here is an another angle of POE

Looking at the topic, the gist is clear that Trevithick‘s discovery led to invention of the locomotive. D is the only choice that directly refers to the discovery, while all the other four refer to Trevithick; So they are wrong. So D.

Completely missed the meaning part of it and voted for C after reading the explaination about D, IMO D

As far as I know, there is nothing wrong with E - both grammatically and meaning wise.

But, it concludes that Trevithick is the one who took the charge of building trains. This is the problem. Unless we know history, we can't answer this. In GMAT, knowledge of history is not required. Hence, we need a passive voice. So, D is correct which says only Trevithick discovery helped building locomotives but not sure whether Trevithick himself led the activity.

This is similar to following question

Only one option says that the discovery led to the 'building of locomotive-driven passenger trains'. That is D.
