Answer: Reducing the powers of self-government in Massachusetts.
Step-by-step explanation:
As a response to the economic damage infringed on Britain by the Tea Party incident in Boston, in 1774, Boston's port was closed down indefinitely until the King declared otherwise. Furthermore, British soldiers were deployed in order to enact the measure and the seat of government was to be moved to Salem, further decreasing Boston's importance with the Royal Navy patroling Boston's harbour.
