Final answer:
England gained a claim in the Americas through the Treaty of Paris, explorations by John Cabot, and migration to Canada during the American Revolution.
Step-by-step explanation:
England gained a claim in the Americas through various historical events and explorations. One significant event was the Treaty of Paris in 1763, which ended the French and Indian War and awarded Britain a vast expanse of territory in North America.
Additionally, explorers like John Cabot, commissioned by Henry VII in 1497, established England's claim to the North American mainland. Despite initial unsuccessful attempts at colonization, England's presence in the Americas grew with the establishment of settlements like the Roanoke colony in 1584.
Furthermore, the American Revolution resulted in many people of English descent, who sided with Britain, migrating to Canada, making it the main British colony in North America.
