Which of the following was a barrier that the Americans with Disabilities Act aimed to address?

The Americans with Disabilities Act (ADA) was enacted to prevent discrimination against individuals with disabilities in various areas of public life, including employment. The focus on employment discrimination is critical because the ADA established provisions that ensure people with disabilities have the right to work and the opportunity to compete fairly for jobs. This includes prohibiting employers from making employment decisions based on a person's disability and requiring reasonable accommodations to be made for employees with disabilities, allowing them to perform their job duties effectively.

While the other options address important issues related to disability rights—such as access to education or housing—they are not the primary focus of the ADA. The act specifically aims to eliminate employment discrimination and foster an inclusive workplace environment for individuals with disabilities, making this the correct choice.
