Answer: True.
Explanation: The news of the tea riot in Boston, referring to the Boston Tea Party incident in 1773, confirmed King George's conviction that there should be no soft policy in dealing with his American subjects. The Boston Tea Party was a protest against British taxation policies, specifically the Tea Act, which granted a monopoly to the British East India Company and imposed taxes on tea imports. This act of rebellion further solidified King George's belief that a strong response was necessary to assert control over the American colonies. As a result, harsher measures, such as the Intolerable Acts, were implemented to punish the colonists and tighten British control.
