Most car manufacturers now offer hybrid vehicles: cars and trucks, which use both standard gasoline and electricity to power their engines. Therefore, consumers who drive hybrid vehicles are using less gasoline now than before these manufacturers began offering hybrid cars and trucks.
Which of the following, if true, most strengthens the argument?

A. Hybrid vehicles generally have higher horsepower than non-hybrid vehicles.
B. Hybrid manufacturers use less gasoline in their manufacturing equipment than non-hybrid manufacturers do.
C. Most hybrid vehicles get the majority of their power from gasoline combustion.
D. The number of miles driven in a hybrid vehicle that are attributable to electricity is greater than the equivalent number of miles that could have been driven with the gasoline used to create that electricity.
E. More electrical power is used driving a hybrid vehicle than an equivalent non-hybrid vehicle.

Restating the argument:

Premise: Most car manufacturers now offer hybrid vehicles (gasoline + electricity).
Conclusion: Consumers who drive hybrids are using less gasoline now than before hybrids were offered.

To strengthen this, we need evidence that owning/driving hybrids actually results in reduced gasoline consumption compared to before.

Options analysis:

A. Hybrid vehicles generally have higher horsepower than non-hybrid vehicles.
Horsepower doesn’t tell us anything about fuel usage — irrelevant to reduced gasoline consumption.

B. Hybrid manufacturers use less gasoline in their manufacturing equipment than non-hybrid manufacturers do.
This talks about manufacturing process fuel use, not consumer gasoline usage when driving.

C. Most hybrid vehicles get the majority of their power from gasoline combustion.
If hybrids still mostly run on gasoline, this could undermine the argument that gasoline use is lower.

D. The number of miles driven in a hybrid vehicle that are attributable to electricity is greater than the equivalent number of miles that could have been driven with the gasoline used to create that electricity.
This says that hybrids get more driving distance from their electric portion than they would from the gasoline needed to produce that electricity — i.e., electricity driving displaces more gasoline driving.
This helps show significant gasoline savings from hybrids, which directly strengthens the conclusion.

E. More electrical power is used driving a hybrid vehicle than an equivalent non-hybrid.
This doesn’t directly address gasoline reduction, and could even imply greater total energy use.

Best Answer:

D — It provides clear quantitative evidence that hybrids replace more gasoline miles with electric miles, supporting the argument that consumers now use less gasoline.

Official Explanation

The argument is that drivers now use less gasoline than they did before the advent of hybrid vehicles. Knowing that the number of miles driven in a hybrid vehicle that were powered by electricity exceeds the number that could have been driven with the gasoline used to make the electricity strengthens the argument. It explains that more miles come from that electricity, proving that hybrid vehicles use less gas than conventional cars and trucks.

Answer: D
