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?

It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

New input case for you: In the latter half of his career Hayek made a number of contributions to social and political philosophy, which he based on his views on the limits of human knowledge, and the idea of spontaneous order in social institutions. He argues in favour of a society organised around a market order, in which the apparatus of state is employed almost (though not entirely) exclusively to enforce the legal order (consisting of abstract rules, and not particular commands) necessary for a market of free individuals to function. These ideas were informed by a moral philosophy derived from epistemological concerns regarding the inherent limits of human knowledge. Hayek argued that his ideal individualistic, free-market polity would be self-regulating to such a degree that it would be 'a society which does not depend for its functioning on our finding good men for running it'.
Output:
When did Hayek begin presenting his ideas on the limits of human knowledge?
