Final answer:
The Clean Air Act reduced pollution, the ADA gave protections to people with disabilities, the Westside Community School District v. Mergens case ensured similar access for school clubs, and the Omnibus Budget Reconciliation Act raised taxes.
Step-by-step explanation:
The Clean Air Act reduced pollution by setting standards for air quality and regulating emissions from industries and vehicles. The Americans with Disabilities Act (ADA) gave protections to people with disabilities by prohibiting discrimination based on disability and requiring employers and public facilities to make reasonable accommodations. The Westside Community School District v. Mergens case ensured that school clubs were given similar access by allowing religious clubs to meet in public schools if they met certain criteria. The Omnibus Budget Reconciliation Act raised taxes to address budget deficits and fund government programs.
