### HideShow timer Statistics

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.

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

The argument presents two possible plans to complete the pipeline: lay it underwater; lay it over the water. The author favors the plan of the bridge. The first boldface portion weakens the bridge option by stating that it's relatively expensive. The second boldface portion is the logical reasoning behind the government's choice to choose the bridge despite its higher cost.

Where in the passage does it imply that the author favors the plan of the bridge? It only says that the government is in favor of the bridge.

The engineering firm suggests building pipe (for the reasons mentioned in the 1st bold face). Govt decides to go with the bridge for the reasons mentioned in the 2nd boldface.
Option D->
The first is evidence in support of the position that the argument chooses to undermine; - True. here "argument chooses to undermine" means "the author chooses to go against the engineering firm's suggestion" the position given in bold states the firm's position not Govt's
the second is the reasoning behind the questioning of that position. -> yes the 2nd bold gives a reason for the Govt's decision.

The author says that "...the government rightly plans to opt for the construction of a bridge". The use of "rightly" tells us that the author agrees with the plan of the govt. If this word is eliminated, then we will not be sure of author's position.

A tranquil scene, to be sure. But there is nothing tranquil about feelings here toward tankers - or more specifically, a pipeline promising to replace many of them. Currently, a pipeline is being proposed to bring approximately 30 trillion cubic feet of stranded gas on the North Slope of Alaska to markets. Many different competing schemes have been investigated, but the most likely to succeed is a pipeline south to the Fairbanks area, and then southeast along the Alaska Highway into Canada.

the trick here is that you are not trying to change or evaluate the argument. Sure there is plenty wrong with the logic but the question asks you about the bolded phrases. Do them one at a time. How does the first sentence fit with the conclusion - The first statemetn somewhat contradicts the conclusion (why would the gov't build a bridge if it were more expensive?). Eliminate C and E for this reason.
the second is supporting information for the conclusion - eliminate A because it does not undermine the position and B becuase it is supporting information, not the viewpoint itself. D is the best answer.

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

The first boldface goes against the argument's conclusion whereas C says 'establish grounds for the argument's conclusion'. Also, the second boldface is not an aim, it is a fact.

So C gets ruled out.

Premise 1:- 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. (Suggestion by Engineering Firm)
Premise 2:- 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.
Premise 3:- 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,
Conclusion: - the government rightly plans to opt for the construction of a bridge.

(A) – Incorrect as the first is not circumstance and second is not contradicting any position.

(B) Incorrect as the first does provide the description of a certain factor but it is not weakening the view point mentioned in the 2nd Bold Face

(C) – This choice is very close to correct choice, but the point which is incorrect is the statement “comparison formulated in order to establish grounds for the argument’s conclusion”. The second bold statement is correct

(D) – It is important here to understand what position the first bold statement is supporting, because once you understand the position, you will understand the second bold statement also. The position here referred is “the low cost associated with laying of pipe on the river-bed” . The first statement indeed is evidence in support to above mentioned position and the second bold statement is the reasoning behind the questioning of that position because the second bold statement informs why you cannot have underwater oil pipline. So statement D is correct answer

(E) – The first bold statement is not a proposal, it is a comparative statement or fact and further the second bold statement is an independent statement and it is not strengthening the proposal mentioned in the first bold statement.
