Scientists wanted to study a particular aspect of Toyota Prius Hybrids.
In Study 1, each Toyota Prius received a full tank of unleaded gasoline. The car then drove 100 miles on the highway at 55 mph. The amount of remaining gasoline was measured.
In Study 2, the experiment was repeated, but the cars were given premium gasoline instead of unleaded. The amount of remaining gasoline was measured. What were scientists studying in this experiment?
A. the decreased impact on atmospheric pollutants using a hybrid car (the Toyota Prius) vs a regular combustion engine car
B. the impact of different types of gas on the mileage of the Toyota Prius
C. the impact on the environment of the different types of gas when used in the Toyota Prius
D. the amount of carbon dioxide produced by the Toyota Prius
