An electric utility has determined that a new power plant is needed and has decided to build either a natural gas-fired plant or a waste-to-energy plant that would serve as both a trash incinerator and a power plant. Surprisingly, although the waste-to-energy plant would produce roughly three times as much air pollution as the gas-fired plant, environmentalists have come out in unanimous support of this option.

Which one of the following, if true, most helps to justify the environmentalists' position?

(A) Modem gas-fired power plants produce significantly less pollution than gas-fired power plants that were built several decades ago.

(B) In the area where the utility operates, both energy use and the volume of trash produced have increased substantially over the last several years.

(C) The waste-to-energy plant would replace an existing trash incinerator that produces much more air pollution than the waste-to-energy plant would.

(D) Most of the environmentalists believe that air pollution is the area's most serious environmental problem.

(E) The vast majority of the air pollution in the area where the utility operates is produced by trucks and automobiles.

Premise: A new powerplant is needed. There's this particular type of powerplant that converts waste to energy (W2E) & emits 3x more pollution than a gas powered plant. Environmentalists are supporting it! The only reason why environmentalists would probably support it would be because in certain particular conditions, the W2E powerplant would be more beneficial. This is covered in choice C

(A) Modem gas-fired power plants produce significantly less pollution than gas-fired power plants that were built several decades ago.
Modern gas-fired power plant is not in question but waste-to-energy plant : Incorrect

(B) In the area where the utility operates, both energy use and the volume of trash produced have increased substantially over the last several years.
It is a good trap; although it brings out a relevant concern, the key aspect that needs to be addressed is pollution : Incorrect

(C) The waste-to-energy plant would replace an existing trash incinerator that produces much more air pollution than the waste-to-energy plant would.
Addresses and strengthens the position of environmentalists directly that why waste-to-energy plant should be used: Correct

(D) Most of the environmentalists believe that air pollution is the area's most serious environmental problem.
Ok, but why should we use waste-to-energy plant? : Incorrect

(E) The vast majority of the air pollution in the area where the utility operates is produced by trucks and automobiles.
How does that information help us, anyway? :Incorrect
