Final answer:
The statement is true. The ADA of 1990 requires that barriers must be removed to ensure Deaf people and others with disabilities have equal access to activities and services, and it prohibits discrimination based on disability.
Step-by-step explanation:
The statement that The Americans with Disabilities Act requires that agencies, businesses, and employers remove barriers that prevent Deaf people from participating in an activity is true. The Americans with Disabilities Act (ADA) of 1990 mandates that public accommodations and services operated by private entities be accessible to individuals with disabilities. This includes removing architectural and communication barriers that are structural in nature. Sidewalk ramps and Braille signs are examples of accommodations required by the ADA and are forms of accessibility for people with disabilities.
Employers are required to make reasonable accommodations for employees with disabilities provided they do not impose an undue hardship on the operation of the employer's business. Additionally the ADA requires that employers, businesses and agencies cannot discriminate against any individual based on a disability reinforcing the right to equal opportunity in the workforce and public spaces.
