EnergyMill Company Advertisement:
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?
(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.

OA C, why not A

kvitkod,

the reason it is not A is because A talks about something in the past. The part where it says an earlier report means that currently wind power has advanced past solar. That would not weaken the ad in any way because we are only concerned with the current marketplace.

(A) An earlier Environmental Impact Coalition report showed that solar power produces fewer pollutants than does wind power

Suppose solar power produces around 10 % pollutants & wind power produces around 12 % pollutants.
This cannot be a strong reason to weaken the claim that wind turbines are the best choice.

C weakens the argument better and hence is the answer.

Isn't this article about emissions/pollutants? C. is about price - I had initially chosen C but A is the only answer that refers to a comparable technology with less pollutant.
