Today the official language of the United States and most of Canada is English. However, French almost became the official language because of a war. The French and Indian War was fought between 1754 and 1763. The name of this war is not accurate because the war was actually between England and France. The Indians fought on the side of the French. France and England were trying to gain control of North America. France held Canada, and England held part of what is now the United States. However, France tried to expand its land by moving southward into New York, Pennsylvania, Ohio, and Virginia. When the French built a fort on the Ohio, River, the residents in Virginia sent George Washington to attack the fort in 1754. However, the French defeated Washington. The French, aided by the Indians, outsmarted the English and won many early battles. Later, the British began to do well against the French. In the final battle in Quebec, Canada, General Wolfe of England faced General Montcalm from France. Both generals died in this battle, but the English outlasted the French and won the battle. Thus, most of North America today has the English culture and language. The word 'gain' in Para. 3 means ______.
A.
