What is the primary aim of the Clean Air Act of 1970?

• A. To regulate water discharges
• B. The law aimed at combating air pollution, by charging the EPA with protecting and improving the quality of the nation's air.
• C. To reduce CO2 emissions in only Europe
• D. To create national parks

Answer: (B)

The main idea of the Clean Air Act of 1970 is to curb air pollution across the United States by giving the EPA authority to protect and improve the nation’s air quality. It set national standards for harmful pollutants and required emission controls from factories and vehicles, aiming to reduce health and environmental risks from polluted air. That’s why this option is the best: it directly describes fighting air pollution and empowering the EPA to safeguard air quality nationwide. The other choices don’t fit: regulating water discharges belongs to the Clean Water Act, reducing CO2 emissions in Europe isn’t the Act’s scope, and creating national parks is unrelated to air-pollution regulation.
