Final answer:
The House of Lords had unfavorable thoughts on the King's address at Parliament concerning the American colonies. The colonies did not receive the response they hoped for, as Parliament declared Massachusetts in rebellion and restricted trade. The Conciliatory Proposition presented by Lord North did not meet colonial expectations.
Step-by-step explanation:
The thoughts of the House of Lords on the King's address at Parliament were not favorable towards the American colonies. Shortly after the arrival of the colonies' petitions, King George III expressed his belief that military force would be necessary to determine whether the colonies would remain subject to Britain or become independent. In response, Parliament declared Massachusetts in rebellion and restricted New England's trade. Parliament's Prime Minister, Lord North, presented a Conciliatory Proposition, but it fell short of colonial expectations. The dissatisfaction with Parliament's response, along with British aggression at Lexington and Concord, led to an unsatisfactory outcome for the colonists.
