Select all of the answers that apply.

Answer 1

The correct answers are the options (A) higher fuel efficiency for cars, (B) mass transit, like buses and trains, (C) automobile emissions tests, and (E) limiting power plant emissions.

Air pollution refers to any change in the quality of the air making it harmful or poisonous. The changes are due to the presence of higher concentration of certain gases, particulate matter and others. The contributors of air pollution are the presence of carbon dioxide, carbon monoxide, oxides of sulphur and nitrogen, chlorofluoro carbon, volatile organic compounds like methane, combined particles and gas forming the aerosols.

Automobiles and industries play an important role in increasing air pollution by the release of these harmful gases. Use of higher fuel efficiency cars can reduce air pollution and smog formes by 50%. The modes of mass commutes like the buses ans trains instead of individuals using vehicles can also reduce the emission of gases like carbon dioxide and carbon monoxide. Automobile emission tests can have an check on the air pollution. Limiting the power plants can reduce the emission of other harmful gases.
