Which of the following was the Americans were disabilities act modeled on was it brown versus Board of Education the civil acts right of 1964 or the equal rights amendment or United States versus Virginia

The Americans with Disabilities Act (ADA) was not directly modeled on any of the options you provided. It was signed into law in 1990 and aimed to prohibit discrimination against individuals with disabilities in various aspects of their lives, including employment, public accommodations, and transportation, among others. However, it is worth noting that the civil rights movement and legislation, such as the Civil Rights Act of 1964, created a framework for advocating for equal rights and non-discrimination, which may have had some influence on the development of the ADA.
