B. People can use additional conservation tactics, like sometimes bicycling.
Explanation:
The use of bicycle to cover short distances would be good change in change in behavior that would enhance the conservational tactics in using fossil fuels.
Most hybrid cars still use gasoline. Although they have dualized energy sources.
Driving hybrid cars more often will not curb the conservation drive for fossil fuel. It will increase more demand for it.
Driving separate hybrid cars will not solve conservation issue of fossil fuels.
Driving the car more is no efficient way to curb the reliance on fossil fuels.
The use of bicycles to cover maybe short distances will be a good approach to conserving more fossil fuels.
Explanation: The strength of the gravitational force between two objects depends on two factors, mass and distance. If the distance is doubled, the force of gravity is one-fourth as strong as before.
