Question

Some automobiles in the United States are fueled by natural gas. What is the primary environmental advantage of natural gas relative to gasoline as a transportation fuel?A. Natural gas is a renewable resource that is usually produced from corn and other agricultural products.B. When natural gas is burned in an automobile engine, the only emission product is water vapor.C. Natural gas combustion emits fewer pollutants.D. There is an extensive retail distribution network for natural gas so that natural gas is available at most gas stationsE. The United States has 60% of the world's proven natural gas reserves.

Answer 1

Natural gas is not a renewable resource, as it is still a fossil fuel, therefore A is incorrect.

The United States has 5% of the world's natural gas reserves, therefore E is also incorrect.

When burned, natural gas emits many compounds, such as carbon dioxide, nitrogen oxide and other. Therefore, B is wrong as well.

There is a distribution network for natural gas, but it is not as available as gasoline. Therefore, D is wrong too.

Natural gas combustion indeed emits fewer pollutants, being a good option for transitioning from fuels that emit lots of pollutants to greener ones. Therefore, the correct answer is C. Natural gas combustion emits fewer pollutants.
