The answer to the crossword puzzle is ADA, which stands for Americans with Disabilities Act. The Americans with Disabilities Act is a civil rights law that prohibits discrimination against individuals with disabilities in all areas of public life, including jobs, schools, transportation, and all public and private places that are open to the general public. It was signed into law in 1990 by President George H.W. Bush and is considered one of the most comprehensive disability rights laws in the world. The ADA ensures that people with disabilities have the same rights and opportunities as everyone else.
