Taking the bus is one way to conserve energy.
a. true
b. false

True

Explanation:

Energy is conserved by taking the bus because the fuel efficiency of the bus is more than that of auto or car. On average the fuel efficiency of a bus is six-time greater than of an auto.

A bus use less energy, at least 8.7% per mile as that of any other typical automobile, therefore, using the bus as a mode of transport is one way to conserve energy. Apart from energy efficiency taking bus reduce pollution because it requires less fuel for transport per person therefore less pollution is released in the environment.

Therefore the statement is true.
