EnergyMill Company Advertisement:

An Environmental Impact Coalition report shows that wind power produces

Which of the following, if true, most seriously weakens the argument in
the advertisement?


OA and Explanation to follow ...


(A) An earlier Environmental Impact Coalition report showed that solar power
produces fewer pollutants than does wind power.
Poweting new developments is our goal. Yes solar power produces fewer pollutants but that does not imply that its the best option
(B) In the last five years, the government has invested more in wind power
than in any other form of green energy.
Looks out of scope
(C) The dispersion of homes in rural areas makes wind power several times
more expensive that conventional energy sources.
This appears to be correct. Since the houses are sparsely populated, the cost of wind power increases and hence it weakens the conclusion
(D) The difference between the number of pollutants generated by wind power
and conventional power sources is quite pronounced.
Looks out of scope
(E) The Environmental Impact Coalition issues reports only once a year.

How can this be?
Nowhere is there any focus on money.
The only thing that is used to estimate if energy is good or bad is the amount of pollutants.
I think it's A.
Anyone?

I think this is a poorly written question -- I too, thought the answer was A because it makes the premise of the argument incorrect. Like others before have stated, if the argument stated that wind power was the best choice for rural areas because it was cheaper, than C would be the best answer.

Upon further research, I found the original question, which includes an explanation for the answers A and C:

Quote:
This is a weaken question. The shift from the first sentence to the second makes the assumption clear. The argument relies on the underlying claim that, because wind power produces the fewest pollutants, it is the best choice. More probably, there are other considerations. The correct choice will likely point out some other consideration that may outweigh the level of pollutants.

Sure, there are other considerations, but we don't know what other considerations would make something better or worse; therefore, we cannot use other considerations to weaken our argument. For all we know, a higher cost could make something better (in terms of quality, for example -- but we would be making an assumption here, too).

Quote:
(A) A reference to an earlier (or different) report is almost always wrong; we have no way of comparing the validity of the two reports. Anyway, it doesn't address the assumption.

It's a huge assumption to think that an earlier report would almost always be wrong just because it came before the argument's report. And it's not true that we don't know the validity of the two reports; we must conclude that the report in Answer A is just as valid, if not more, than the report from the argument because the question says "if true".

Quote:
(C) This is correct. This is a strong reason why wind power may not be the best choice for new rural areas.

And again, for C, wouldn't we be making an assumption to say that wind power is not the best choice just because it is more expensive? There are plenty of things that are more expensive, but "better". Usually, when we say something is better, we have certain criteria -- in this case, our criteria for "better" is the amount of pollutants it produces. Based solely on this information, and if we know that solar power produces less pollutants than wind power, then we can conclude that solar power is actually the best option.

Of course, maybe I just have a bias against the question now because I got it wrong :wink:

EDIT: after thinking about it, making the premise not true is not the most effective way to weaken an argument. Attacking assumptions in the argument is the better strategy, but again, this question is badly worded. It perhaps might be better written as such:

An Environmental Impact Coalition report shows that wind power produces the fewest pollutants among all green energy alternatives. Since rural areas cannot afford most conventional energy alternatives, EnergyMill wind turbines are the best choice for powering new developments in rural areas.

Which of the following, if true, most seriously weakens the argument in the advertisement?

(A) An earlier Environmental Impact Coalition report showed that solar power produces fewer pollutants than does wind power.
(B) In the last five years, the government has invested more in wind power than in any other form of green energy.
(C) The dispersion of homes in rural areas makes wind power several times more expensive that conventional energy sources.
(D) The difference between the number of pollutants generated by wind power and conventional power sources is quite pronounced.
(E) The Environmental Impact Coalition issues reports only once a year.

It is clearly A ... since solar power produces fewer pollutants ... it is the best option not wind power...

Official Explanation


Answer: C - This is a weaken question. The shift from the first sentence to the second makes the assumption clear. The argument relies on the underlying claim that, because wind power produces the fewest pollutants, it is the best choice. More probably, there are other considerations. The correct choice will likely point out some other consideration that may outweigh the level of pollutants.

(A) A reference to an earlier (or different) report is almost always wrong; we have no way of comparing the validity of the two reports. Anyway, it doesn't address the assumption.

(B) The level of government investment is similar to a separate report, as in (A). If anything, it strengthens the claims of wind power supporters, but to be a strengthener, we must assume that the government is making a valid choice.

(C) This is correct. This is a strong reason why wind power may not be the best choice for new rural areas.

(D) This is an irrelevant comparison. The evidence in the argument compares wind power to other green energy alternatives. If anything, this point strengthens the argument, but not very effectively.

(E) The frequency of reports has no effect whatsoever on the argument.

C is the clear choice. the argument assumes that because wind power has fewer pollutants it is the best choice. but "Best" choice might depend on a variety of factors. so the answers that point to one of the factors and says if this is considered wind power may not be the best will weaken the argument. C does that clearly

I think this is a poorly written question and cannot see how the OA is C. The question asks, "Which of the following, if true, most seriously weakens the argument in the advertisement?" The argument in the advertisement, as I read it, is that, because wind power produces the fewest pollutants, it is therefore the best choice. Nowhere in the advertisement does it take even take the cost (or any other variables besides pollutant production) of these energy alternatives into account, which is what andwer choice C is doing. Therefore, C, while being a real-world consideration, does not directly weaken the argument provided in the advertisement.

I believe the correct answer is A as that most directly speaks to the argument explicitly in the advertisement text. If anyone can explain how C weakens the argument without extrapolating and taking other variables into account, which the advertisement does not do, please explain.

The problem with A is there is a word "earlier" which makes the finding outdated... That's why i picked C.

I think ... something wrong with this question..

"Best choice"..the term is subjective.. it differs from subject to subject.. and that is not clearly defined in this question.

Poor quality Question.

Re: EnergyMill Company Advertisement: An Environmental Impact Coalition [#permalink]
I hope I wont get such kind of poorly formulated questions on GMAT
The EnergyMill Company Advertisement announces:
Quote:
An Environmental Impact Coalition report shows that wind power produces the fewest pollutants among all green energy alternatives. This shows that EnergyMill wind turbines are the best choice for powering new developments in rural areas.


Which of the following, if true, most seriously weakens the argument in the advertisement?
Definitely, it's "A" 'cause it's about green energy but not about the viable investment. Questions doesn't specify if it's an Advertisement for potential investors or for the government. And the main argument in the statement is marked above in bold:
wind power produces the fewest pollutants among all green energy alternatives - statement
best for powering new developments in rural areas - conclusion
So test takers assume that having the fewest pollutant solution is crucial for for powering new developments in rural areas, which makes total sense, protect the planet

In the meantime, even if we think about financial aspects of investing in the green power answer C doesn't assume that the current dispersion of homes will remain the same in 10 -15 -20 years, and investing in green energy is a long-term investment, nobody expects to see results right away or in 1 year. The C answer doesn't state the dispersion will remain the same for the next x-years or probably will be the same
(C) The dispersion of homes in rural areas makes wind power several times more expensive that conventional energy sources.

Such kind of questions really confuse GMAT candidates, you feel like an idiot
