Final answer:
The British gained territorial gains, supremacy in North America, and war debt from winning the French and Indian War.
Step-by-step explanation:
From winning the French and Indian War, the British gained several benefits. Firstly, they acquired significant territorial gains. The Treaty of Paris in 1763 awarded the British control over Canada and all French territory east of the Mississippi River, including Florida. Secondly, the British gained supremacy in North America, as they eliminated France as a major colonial power in the region. This allowed them to expand their influence and control over the colonies. Finally, the British also gained significant war debt, which contributed to tensions and ultimately played a role in the American Revolution.
