An engineering firm has suggested the construction of an underwater oil pipe to complete the supply route of an oil system connecting the source of the oil to various power stations. The route crosses a 1.3 mile-wide river, and to build a bridge for the pipe would cost twice as much as it would to lay the pipe on the riverbed. In order to reduce the risk of water pollution caused by ruptures between the pipe's segments due to water pressure, a fairly likely occurrence at some point in the pipe's duration of use, the government rightly plans to opt for the construction of a bridge.

In the argument given, the two portions in boldface play which of the following roles?

(A) The first explains circumstances that call the position taken by the author into question; the second holds factual information which contradicts that position.
(B) The first provides a description of a certain factor which may weaken the argument's favored viewpoint; the second is that viewpoint.
(C) The first is a comparison formulated in order to establish grounds for the argument's conclusion; the second is the aim leading to that conclusion.
(D) The first is evidence in support of the position that the argument chooses to undermine; the second is the reasoning behind the questioning of that position.
(E) The first is a proposal that is supported by the position of the argument; the second is further evidence used to strengthen that proposal.

I think the correct answer is D

Position to be undermined: laying of pipeline is cheaper

evidence in support of position build a bridge for the pipe would cost twice as much as it would to lay the pipe on the riverbed

reasoning behind questioning of that position to reduce the risk of water pollution caused by ruptures between the pipe's segments due to water pressure

I hate boldface questions. I thought the answer was A, but after reading the explanation for D, I agree it should be D.

(A) The first explains circumstances that call the position taken by the author into question; the second holds factual information which contradicts that position.
First is correct;Ssecond doesnot contradict,it helps support position..OUT
(B) The first provides a description of a certain factor which may weaken the argument's favored viewpoint; the second is that viewpoint.
FIRST IS CORRECT;SECOND IS NOT A VIEWPOINT RATHER IS ANOTHER FACTOR ..OUT
(C) The first is a comparison formulated in order to establish grounds for the argument's conclusion; the second is the aim leading to that conclusion.
SECOND IS NOT THE AIM,IT IS A FACT..OUT
(D) The first is evidence in support of the position that the argument chooses to undermine; the second is the reasoning behind the questioning of that position.
FIRST IS CORRECT;SECOND IS A FACT WHICH ACTS LIKE A REASON..CORRECT
(E) The first is a proposal that is supported by the position of the argument; the second is further evidence used to strengthen that proposal.
FIRST IS NOT A PROPOSAL..OUT

In the argument given, the two portions in boldface play which of the following roles?

(A) The first explains circumstances that call the position taken by the author into question; the second holds factual information which contradicts that position. --> support not contradict.
(B) The first provides a description of a certain factor which may weaken the argument's favored viewpoint; the second is that viewpoint.--> the second is not the conclusion or viewpoint (only support).
(C) The first is a comparison formulated in order to establish grounds for the argument's conclusion; the second is the aim leading to that conclusion. --> not establish but against
(D) The first is evidence in support of the position that the argument chooses to undermine (=support the engineer's view); the second is the reasoning behind the questioning of that position. (=reason against the engineer's view)-->correct
(E) The first is a proposal that is supported by the position of the argument; the second is further evidence used to strengthen that proposal. -->the first doesnt support.


My ans is D

Hey Guys,

Just wondering why nobody has considered (C)?

The first is a comparison formulated in order to establish grounds for the argument's conclusion; the second is the aim leading to that conclusion.

I think some people interpret establish grounds to mean "offers some sort of evidence in SUPPORT of the conclusion; however, I disagree with that assessment.

Establish grounds, to me, simply means to provide information that will aid in one's ability to evaluate the argument.

The first boldfaced portion definitely does that. Certainly, it provides some evidence that might seem to contradict our choice, but really the statement just plays a 'devil's advocate' role and points out a counter-argument which we then show to be overridden.

Part of any convincing argument is consideration of the other side. So I believe that the first boldface portion does establish grounds.

Also, the second part does seem to be the aim leading to that conclusion.

The conclusion is that we have reason to build the albeit more expensive bridge.

The aim of building this bridge is indeed to reduce the risk of water pollution caused by ...

Am I totally off-base here?

Edit: while I concede that 'grounds' implies support, counterarguments definitely help to establish grounds. So if the question said that 'the first bolded statement is grounds', I'd agree that this would be incorrect. However, if the question said that 'the first bolded statement helps to establish grounds', I'd say that this is definitely correct. So the actual option, 'establishes grounds', I believe is ambiguous, and open to either interpretation.

HI Matt,

I think your long argument sort of tells you that you've had to work too hard to make this fit...

If you look at D - it's much more simple and clear that it's correct.

Now, I can if I think long and hard sort of understand your reasoning behind C - even though in the end I don't agree with it, but crucially on GMAT we're not looking for a long discussion of right and wrong. It's multiple choice - pick the best answer and move on. That answer is D.

If you have questions over D and think C is better - then that's a different discussion...

Hi James,

I suppose you're right. This is one of the many psychological obstacles that are in the way of my achieving a great score.

While I realize on an intellectual level that the GMAT is just about choosing the best answer, it still REALLY bothers me if I see more than one answer that seems to fit the question.

Thanks
