Final answer:
Public buildings and schools are required to accommodate the needs of the handicapped, including providing ramps and elevators, as mandated by the Americans with Disabilities Act (ADA) of 1990.
Step-by-step explanation:
The requirement for public buildings and schools to provide reasonable accommodations, such as ramps and elevators, for individuals with disabilities is mandated by the Americans with Disabilities Act (ADA) of 1990. Under the ADA, public accommodations must be accessible to persons with disabilities, ensuring opportunities for the same level of service as the general public. This includes a variety of provisions such as sidewalk ramps and Braille signs, making everyday activities more accessible for individuals with disabilities. Additionally, the ADA stipulates that employers make reasonable accommodations for employees with disabilities to perform their jobs effectively, thereby combating discrimination in the workplace.
