Explanation:

Boston began tearing down its hills to make new land that remained filled with wetlands and marshes. Boston surrounded with bodies of water, mainly swamp.  The peninsula had several hills, including Pemberton Hill, Beacon Hill, Fort Hill, Mt. Vernon, and Copp’s Hill. Several water bodies, including ponds and wetlands filled with soil from hills. The new plot used for building housing. As more waterbodies filled, the land became available for the people to settle in. As it process, the city of Boston was becoming large and as well in population in coming years.
