Final answer:
The ADA requires cafeterias to have 36" wide aisles between tables and counters to ensure accessibility for individuals with disabilities, conforming with the ADA's standards for public accommodations.
Step-by-step explanation:
The question relates to the Americans with Disabilities Act (ADA) which was enacted in 1990 to ensure that people with disabilities have equal access and opportunities in public spaces and employment. According to the ADA Standards, public spaces such as cafeterias are required to provide accommodations that facilitate accessibility for individuals with disabilities. While the ADA does not specifically mention 40" high bars or adjustable tables as a requirement, it does mandate that spaces must be made reasonably accessible. The correct answer is the provision that requires 36" wide aisles between tables and counters in cafeterias to allow for the maneuvering of wheelchairs and other mobility aids, which is a common interpretation of making a space accessible under the ADA guidelines.
