Question

what is the purpose of the clean water act?
to regulate international agricultural practices
to control discharges of pollutants into u.s. waters
to promote deforestation to lower wood prices

Explanation:

The Clean Water Act (CWA) in the U.S. is primarily focused on regulating water pollution. The first option is incorrect as it relates to international agricultural practices, not water. The third option is incorrect as deforestation is unrelated to the CWA. The second option accurately describes the CWA's purpose of controlling pollutant discharges into U.S. waters.

Answer:

B. to control discharges of pollutants into U.S. waters (assuming the middle option is labeled B; if the options are unlabeled by position, the middle option: "to control discharges of pollutants into U.S. waters")
