I want to know the answer to the following question:
What is the MWRA?
All the background I'm provided with is that "In addition to city government, numerous commissions and state authorities—including the Massachusetts Department of Conservation and Recreation, the Boston Public Health Commission, the Massachusetts Water Resources Authority (MWRA), and the Massachusetts Port Authority (Massport)—play a role in the life of Bostonians.". Is that enough to answer the question?
