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.
Output: When was the French and Indian War?

New input case for you: The major and native language spoken in the Punjab is Punjabi (which is written in a Shahmukhi script in Pakistan) and Punjabis comprise the largest ethnic group in country. Punjabi is the provincial language of Punjab. There is not a single district in the province where Punjabi language is mother-tongue of less than 89% of population. The language is not given any official recognition in the Constitution of Pakistan at the national level. Punjabis themselves are a heterogeneous group comprising different tribes, clans (Urdu: برادری‎) and communities. In Pakistani Punjab these tribes have more to do with traditional occupations such as blacksmiths or artisans as opposed to rigid social stratifications. Punjabi dialects spoken in the province include Majhi (Standard), Saraiki and Hindko. Saraiki is mostly spoken in south Punjab, and Pashto, spoken in some parts of north west Punjab, especially in Attock District and Mianwali District.
Output:
What is Punjab's major language?
