Answer to Question 1

ANS: A
Point sources of pollution are identifiable sources of air pollution, such as a smoke stack. Non-point sources come from more diffuse exposures, such as from cars and trucks. The amount of fossil fuel that is consumed and ground ozone levels do not identify sources of air pollution.

Answer to Question 2

ANS: C
Mobile sources such as cars and trucks are the greatest single source of air pollution in the United States. Waste incineration and power plants are major contributors after motor vehicles. Molds contribute to poor indoor air quality.
