Answer:
Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Step-by-step explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.
