Many households have replaced

by BTGmoderatorDC » Wed Jan 24, 2018 4:34 am
Many households have replaced at least one of their traditional gasoline powered cars with electric cars. It is thus clear to see that less gasoline is being used as a result of the operations of these households than they would have used if they had maintained their original cars.

Which of the following, if true casts the most doubt on the argument above?

A) More gasoline was used to produce the new electric cars than was used to produce the traditional cars.
B) Many of the households that have replaced at least one of their traditional cars have decreased the amount of miles they drive.
C) Some of the households that have replaced at least one of their traditional cars use their electric car more often than their traditional car.
D) Electric companies use gasoline powered generators to produce at least some of the electricity they provide to their customers.
E) A fully charged electric car travels fewer miles than a gasoline powered car with a full tank.

Can some experts explain the best Option?
