Final answer:
The growing distrust between the American colonists and the British Parliament was caused by the British government's tightening control over the colonies, the harsh response to the Boston Tea Party, and news of the colonists' reactions and protests.
Step-by-step explanation:
The growing distrust between the American colonists and the British Parliament was caused by a series of events.
Firstly, the British government tightened its control over the colonies by passing acts to raise money for protecting and maintaining the colonies.
These acts included taxing the colonies without their consent, which the colonists saw as a violation of their rights under the British constitution.
Secondly, the harsh British response to the Boston Tea Party, such as sending troops to Boston and closing the harbor, escalated tensions further.
Lastly, news of the colonists' reactions and the violent protests in the colonies worsened the political situation in Great Britain.
