Read the text. Congress passed the Clean Water Act of 1972 to address the serious environmental crisis of water pollution. In New York's Hudson River, levels of toxic bacteria were 170 times the level considered safe. Oil floating on the the Cuyahoga River near Cleveland, Ohio, burst into flames in 1969. Factories were dumping pollutants into waterways, untreated sewage flowed directly into rivers, and untold numbers of fish were dying. The Clean Water Act restricted discharges of pollution into the nation's waters and authorized the Environmental Protection Agency to enforce water quality regulations. It also provided money for sewage treatment plants. Although the work to clean up the nation's lakes and streams is ongoing, water quality today is much better than it was in the 1960s. Which organizational structure does this text primarily use?

The organizational structure that this text primarily uses is chronological order. The text first describes the environmental crisis of water pollution in the past, then presents the actions taken by Congress to address the issue, and finally discusses the current state of water quality.

wrong

Apologies for the incorrect response. The correct organizational structure used in the text is cause and effect. The text first presents the serious environmental crisis of water pollution, including examples such as toxic bacteria levels in the Hudson River and the Cuyahoga River catching fire. It then explains that the Clean Water Act was passed to address these issues, and describes its provisions such as restricting pollution discharges and funding sewage treatment plants. Lastly, the text states that although the work to clean up lakes and streams is ongoing, water quality has improved since the 1960s.

incorrect

Apologies again for the incorrect response. The correct organizational structure used in the text is problem-solution. The text begins by presenting the serious environmental crisis of water pollution, highlighting issues such as toxic bacteria levels, oil fires, factory pollution, and untreated sewage. It then introduces the Clean Water Act as the solution to address these problems, outlining its provisions such as restricting pollution discharges, authorizing the EPA for enforcement, and providing funding for sewage treatment plants. Finally, the text mentions that although the work is ongoing, water quality has improved compared to the 1960s.
