Example Input: Question: Of the two teams Gallagher was loaned to in 1989, which had more wins that year? Passage:In August 1982 he joined Bruce Rioch's Torquay United on non-contract terms following his return to the UK. He was rewarded with a one-year contract, scoring nine times in 42 league games as well as the winning goal in the FA Cup tie at home to Oxford United that saw the Gulls through to the Fourth Round for only the fourth time in their history. Despite a successful season, he left at the end of it, returning to Wisbech Town debuting in the 1–0 Eastern Counties League victory at Tiptree United on 20 August 1983. He moved on to join Irish side Drogheda United, helping them defeat Athlone Town 3–1 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup. Gallagher returned to Wisbech Town for the 1984–85 season before rejoining another of his former clubs, Peterborough United, in August 1985. His second spell proved his strongest in league football, as he netted 24 goals in 82 league games, earning a move to Wolverhampton Wanderers in June 1987. He found opportunities limited at Molineux due to the prolific partnership of Steve Bull and Andy Mutch, but did play at Wembley in their victory in the Sherpa Van Trophy in May 1988. He was loaned to both Wisbech Town and Kettering Town during the following season before being released in September 1989, and joining Conference side Boston United.

Example Input: Question: How old was Charles Anderson Dana when Edward Page Mitchell replaced him as The Sun's editor? Passage:Edward Page Mitchell (1852–1927) was an American editorial and short story writer for The Sun, a daily newspaper in New York City. He became that newspaper's editor in 1897, succeeding Charles Anderson Dana. Mitchell was recognized as a major figure in the early development of the science fiction genre. Mitchell wrote fiction about a man rendered invisible by scientific means ("The Crystal Man", published in 1881) before H.G. Wells's The Invisible Man, wrote about a time-travel machine ("The Clock that Went Backward") before Wells's The Time Machine, wrote about faster-than-light travel ("The Tachypomp"; now perhaps his best-known work) in 1874, a thinking computer and a cyborg in 1879 ("The Ablest Man in the World"), and also wrote the earliest known stories about matter transmission or teleportation ("The Man without a Body", 1877) and a superior mutant ("Old Squids and Little Speller"). "Exchanging Their Souls" (1877) is one of the earliest fictional accounts of mind transfer. Mitchell retired in 1926, a year before dying of a cerebral hemorrhage.
