Final answer:
The statement 'Prior to the Seven Years' War, Britain had not tried to regulate the colonies' economy' is false.
Step-by-step explanation:
False
Prior to the Seven Years' War, Britain had not tried to regulate the colonies' economy. However, after the war, the British government decided to tighten its control over the colonies and began passing acts to raise money and regulate trade. This change in policy was one of the factors that led to the tensions between Great Britain and the American colonists.
