Question

What helped local governments in the United States to reduce air pollution?


Choose the best answer from the options below:
A The Environmental Process Agency
B The Clean Air Act
C Carpooling
D All of the above

Answer 1

The best answer is **B The Clean Air Act**.

While carpooling (C) can help reduce air pollution at a local level, the Clean Air Act (B) provides a comprehensive framework that has empowered local governments across the U.S. to implement regulations and strategies to improve air quality. The Environmental Process Agency (A) does not appear to be a recognized agency in this context, and "All of the above" (D) would not be accurate since A is not applicable.
