Many American legislators have concluded that an increase in tax incentives for ethanol production would lessen our dependence on foreign oil.

A. It takes 1.5 gallons of oil to produce 1 gallon of ethanol.
B. Electric cars are cheaper to operate than cars running on the ethanol fuel mix.
C. It costs thousands of dollars to retrofit an automobile to run on the ethanol fuel mix.
D. The ethanol/gasoline blend emits more pollution that regular gasoline.
E. The ethanol/gasoline blend has not been widely adopted in Europe.

Increase in tax benefit would encourage people to produce more ethanol. But, if we need more quantity of oil to produce smaller quantity of ethanol, then we will need more oil than we are using currently
B. Electric cars are cheaper to operate than cars running on the ethanol fuel mix.
Operating costs is not a concern of the conclusion
C. It costs thousands of dollars to retrofit an automobile to run on the ethanol fuel mix.
Retrofitiing costs is not a concern of the conclusion
D. The ethanol/gasoline blend emits more pollution that regular gasoline.
Polution is not a concern of the conclusion
