$ADA

Here's a more detailed explanation:

The Americans with Disabilities Act (ADA) is a comprehensive civil rights law that prohibits discrimination based on disability. It ensures that people with disabilities have the same rights and opportunities as everyone else.

When someone refers to an "ADA pair," they are likely talking about two things that are related to or compliant with the ADA. This could refer to:

* Two individuals who are both covered by or advocates for the ADA. For example, "The two lawyers in disability rights formed an ADA pair for the lawsuit."

* Two objects, services, or concepts that are both designed to be ADA-compliant or are discussed in the context of ADA requirements. For example:

* "They needed an ADA pair of ramps for the building's entrances." (Two ramps designed to meet ADA specifications)

* "The architects reviewed an ADA pair of design plans to ensure accessibility." (Two sets of plans, both focusing on ADA compliance)
