The Clean Air Act was originally passed in which year?

Explanation:
The question is testing when the Clean Air Act first became law and how the program evolved over time. The act was originally passed in 1963, creating the initial federal role in reducing air pollution and supporting state programs with funding and research. It wasn’t until the major amendments in 1970 that the framework became a comprehensive nationwide regulatory program with enforceable standards and deadlines, and subsequent updates in 1977 and 1990 expanded and strengthened those efforts. The year to remember for the original enactment is 1963; 1970 marks the big strengthening, not the initial passage.
