Greenville, an agricultural city, will be doubling its cattle population the coming year. To make the city more conducive for cattle rearing, Greensville’s mayor plans to reduce the amount of greenhouse gasses generated in the city. He plans to promote widespread use of solar powered vehicles rather than gasoline powered ones; he therefore plans to ban gasoline sale for use in vehicles. He argues that solar power represents a far greener source of energy (producing lesser greenhouse gasses) than does fossil fuel.

All of the following call into question the feasibility of the proposed plan, EXCEPT

A The process of making solar cells that will power vehicles involves the use of more fossil fuel than what it would take to power a conventional gasoline vehicle through its entire life cycle
B Since most of the citizens of Greensville prefer gasoline powered vehicles, they will drive to their neighboring cities to fuel up, when they need to
C It has been found that the amount of greenhouse gasses produced by cattle far exceeds that of those produced by gasoline powered vehicles
D New research has shown evidence that disproves the popular notion that vehicle emissions are causative for the production of greenhouse gasses.
E There was a decrease of 20 percent in the production of solar cells last year

Question Type: Weaken Except

Plan: To reduce greenhouse gases, use solar powered vehicles. Ban gasoline sale for vehicles consuming gasoline.

A. The process of making solar cells that will power vehicles involves the use of more fossil fuel than what it would take to power a conventional gasoline vehicle through its entire life cycle - Weakens. Doesn't help reduce greenhouse gases.

B. Since most of the citizens of Greensville prefer gasoline powered vehicles, they will drive to their neighboring cities to fuel up, when they need to - Weakens.

C. It has been found that the amount of greenhouse gasses produced by cattle far exceeds that of those produced by gasoline powered vehicles - Weakens.

D. New research has shown evidence that disproves the popular notion that vehicle emissions are causative for the production of greenhouse gasses. - Correct

E. There was a decrease of 20 percent in the production of solar cells last year - Since there was a 20% decrease in production of solar cells, there is a chance that the supply didn't meet the demand.

the proposal is this — reduce greenhouse gases to improve cattle rearing by using solar vehicles instead of gasoline powered ones.

If gasoline powered vehicles do not emit greenhouse gases, then the proposal will fall apart — no reduction in green house gases will be achieved.

(I think this problem is terrible; the logic employed does not make sense either. Ignore this one)

D is also questioning the feasibility of the plan.
If Vehicle pollution is not a cause for green house emission then the plan will not work.As the plan is based on this assumption itself.

E is the right answer.

GMATNinja, gmat1393, GMATNinjaTwo, nightblade354 i believe the OA is wrong,

Option D also weakens the proposal,

Only E does not weaken it.

Please help

In a closer look, option E makes sense. The proposal is that "To make the city more conducive for cattle rearing, Greensville’s mayor plans to reduce the amount of greenhouse gasses generated in the city. The mayor also argues that solar power represents a far greener source of energy (producing lesser greenhouse gasses) than does fossil fuel. Hence, even if vehicle emissions are not causative for the production of greenhouse gasses, the mayor's plan to reduce greenhouse gasses will not be affected anyway because solar-powered vehicles emit far less greenhouse gasses than do gasoline-powered vehicles.
