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?
This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' 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: Everton's biggest rivalry is with neighbours Liverpool, against whom they contest the Merseyside derby. The Merseyside derby is usually a sellout fixture, and has been known as the "friendly derby" because both sets of fans can often be seen side by side red and blue inside the stadium both at Anfield and Goodison Park. Recently on the field, matches tend to be extremely stormy affairs; the derby has had more red cards than any other fixture in Premiership history. The rivalry stems from an internal dispute between Everton officials and the owners of Anfield, which was then Everton's home ground, resulting in Everton moving to Goodison Park, and the subsequent formation of Liverpool F.C., in 1892.
Output:
Who is the Everton Football Club's biggest rivals?
