Answer:
The Americans with Disabilities Act (ADA) became a law in 1990, and it's a civil rights law that disallows discrimination or prejudice against individuals with disabilities in all areas of public life including jobs, housing, and schools.
Explanation:
The ADA is saying (claiming) that unfair and unnecessary discrimination and prejudice against people with disabilities is continuing (on going, even with the ADA in place). Â
And, because it is continuing, it is preventing people with disabilities to compete on an equal basis. (i.e., if a disabled person is applying for a job, an apartment, or a school, a person Not disabled would be more likely to fill those positions because of unfair discrimination and prejudice against the disabled person.)
