Option (C)

As this is the most direct and unambiguous option. Modifier "800-mile long" is closest to its noun, and the function of Trans Alaska Pipeline System is clear.

Option (C) is correct as it maintains the gist of the sentence without any unwarranted positioning of words.

Another for C. It is clear and direct.

IMO - C
Because it is the only on in Active Voice

What about the parallelism issue of 'to the refineries of North America and to the world.'? Shouldn't it be 'to the refineries of North America and the world.' Isn't the word 'to' out of place in front of 'the world'?

I used to know English until I started studying for this, and now Im all mixed up. Please help. Thanks

I think the sentence implies that Crude oil is supplied to refineries in North America and the world. If we split C, it appears that crude oil is supplied to "Refineries in North America" and "To the world".

D correctly specifies that crude oil is supplied to the refineries of North America and the world.

Answer is D for me.

B or D

IMO D Because of the parallelism.

This is another terrible Veritas sentence correction question. Answer C does not make sense. The conjunction presents 2 thoughts that are not parallel and not logical. "To the refineries of North America and to the world" is ambiguous and redundant.

First off, "to the refineries of North America" and "to the world" are redundant thoughts because North America is part of the world. It should be "to the rest of the world" to avoid redundancy. Second of all, shouldn't the part after "and" be "to those of the rest of the world" in order to create parallel structure for where the crude oil and natural gas are going?

D fixes the parallelism issue, but not the redundancy issue. Official GMAT questions will never have errors even in correct answers, so throw this question out the window. I've seen this on several Veritas questions where answers are eliminated automatically because of passive voice. That is WRONG. Style is never the first criteria to eliminate answers. Grammar and meaning are.

(c)- pipeline is just a mode used to supply....its not the supplier.
so shuldnt this option be incorect
btw can u provide clear insight to rule out other options..

There is crude oil and natural gas supplied to the refineries of North America and to the world by the 800-mile-long Trans Alaska Pipeline System.

Incorrect. This sentence is awkward, but it is also incorrect because "is" is a singular verb, and we need its plural form "are" because the first part of the sentence talks about two things: crude oil and natural gas.

By the 800-mile-long Trans Alaska Pipeline System the refineries of North America and the world are supplied with crude oil and natural gas.

Incorrect. "By the" should never start this kind of sentence. It is a conjunction phrase that is meant to clearly join "the crude oil and natural gas" with "the refineries of North America and the world."

The 800-mile-long Trans Alaska Pipeline System supplies crude oil and natural gas to the refineries of North America and to the world.

Correct. This sentence is clear and grammatically correct. It's not a great sentence because "and to the world" has a redundant "to" - but that is more of a style issue rather than an issue of whether or not the sentence is correct.

The refineries of North America and the world are supplied with crude oil and natural gas by the 800-mile-long Trans Alaskan Pipeline System.

Incorrect. The sentence is written in the passive form, with the subject "the 800-mile-long Trans Alaskan Pipeline" at the end of the sentence instead of at the beginning.

Crude oil and natural gas are supplied by the 800-mile-long Trans Alaska Pipeline System to the refineries of North America and to the world.

Incorrect. Another passive form of the sentence. In this case, the subject "the 800-mile-long Trans Alaskan Pipeline" is in the middle of the sentence instead of at the beginning.

This question is made tricky because the third answer, the correct one, is stylistically imperfect. It kind of throws you off. But don't worry! The answers on the GMAT exam won't give you that kind of stylistic worry.
