Final answer:
The thoughts of the House of Commons on the King's address at Parliament were not favorable to the American colonies. Parliament declared Massachusetts to be in rebellion and imposed trade restrictions. The Conciliatory Proposition offered limited concessions, but did not meet colonial expectations.
Step-by-step explanation:
The thoughts of the House of Commons on the King's address at Parliament were not favorable to the American colonies. After receiving the petitions from the colonies, King George III expressed the view that military force might be necessary to determine if the colonies should remain subject to Britain or become independent. In response, Parliament declared Massachusetts to be in rebellion and imposed restrictions on trade with New England. The Prime Minister, Lord North, presented a Conciliatory Proposition which offered limited concessions but fell short of colonial expectations. These unsatisfactory responses, coupled with British aggression at Lexington and Concord, led to further tensions between the colonies and Britain.
