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.
Solution: When was the French and Indian War?

New input: The return of former player George Graham as manager in 1986 brought a third period of glory. Arsenal won the League Cup in 1987, Graham's first season in charge. This was followed by a League title win in 1988–89, won with a last-minute goal in the final game of the season against fellow title challengers Liverpool. Graham's Arsenal won another title in 1990–91, losing only one match, won the FA Cup and League Cup double in 1993, and a second European trophy, the European Cup Winners' Cup, in 1994. Graham's reputation was tarnished when he was found to have taken kickbacks from agent Rune Hauge for signing certain players, and he was dismissed in 1995. His replacement, Bruce Rioch, lasted for only one season, leaving the club after a dispute with the board of directors.
Solution:
What former Arsenal player became manager in 1986?
