Example: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.

Problem: Ethnically and linguistically the population of the Republic of the Congo is diverse—Ethnologue recognises 62 spoken languages in the country—but can be grouped into three categories. The Kongo are the largest ethnic group and form roughly half of the population. The most significant subgroups of the Kongo are Laari in Brazzaville and Pool regions and Vili around Pointe-Noire and along the Atlantic coast. The second largest group are the Teke who live to the north of Brazzaville with 17% of the population. Boulangui (M’Boshi) live in the northwest and in Brazzaville and form 12% of the population. Pygmies make up 2% of Congo's population.
Solution: How many languages are used in the Congo?
