Final answer:
Gasoline power's primary benefit is its independence from an external power source, enabling high energy transfer rates for vehicles. It is not inherently the cheapest or fastest source, but its energy density and refueling efficiency are significant advantages.
Step-by-step explanation:
A benefit of gasoline power is that it does not need an outside power source (option a). Gasoline engines, used in vehicles, offer a dense energy source which allows for the quick transfer of energy, enabling efficient mobility. While other sources like solar cells can capture sunlight to generate electricity, they cannot match the energy transfer rate that gasoline provides. For instance, when a car is being fueled, it can transfer energy at a rate equivalent to what 3,000 homes use while running air conditioning. This demonstrates the efficiency and speed with which gasoline can deliver energy to a system, such as an engine.
However, it should be noted that gasoline combustion is not without its downsides. For example, it generates heat (so option b is incorrect), and while it may not be the cheapest form of power (making option c incorrect), it also isn’t necessarily faster than all other power sources in all contexts (dissenting option d). Gasoline's true strength lies in its energy density and the infrastructure built around it, which enables rapid refueling compared to the slower charging times of electric vehicles.
