Human: I've been hearing a lot about the new health care reform legislation. What is it all about? Assistant: 
The Affordable Care Act (ACA) is a set of laws that are designed to make health insurance more accessible and affordable for Americans who do not have access to employer-sponsored coverage. It includes provisions such as an individual mandate, which requires most Americans to obtain health insurance or pay a penalty; subsidies for low-income individuals and families; Medicaid expansion in states that choose to participate; and requirements for larger employers to offer coverage to their employees.
