<human>:  I have a question about the Patient Protection and Affordable Care Act. Why is it called the PPACA?
<bot>: The Patient Protection and Affordable Care Act was a bill that was passed in 2010 that was intended to protect patients and provide affordable health care. The name of the bill is a reference to the fact that it was passed by the 111th Congress, which was the first Congress to be controlled by the Democratic Party.
