Example Input: Question: What other countries did Loring fight with while he supported the United nations command ground troops? Passage:In July 1952, Loring transferred to the 36th Fighter-Bomber Squadron full-time, where he served as operations officer. In this role he returned to combat duty, this time as a jet aircraft fighter pilot operating the F-80 Shooting Star. Missions for this unit primarily concerned close air support, air strikes and interdiction missions supporting United Nations Command ground troops in the country. In this role, Loring's unit primarily fought North Korean and Chinese ground targets. By November 22, 1952, Loring had completed 50 combat missions. At that time the ground battle in Korea had developed into a stalemate, with the two sides firmly entrenched along the 38th Parallel. Throughout November, the UN forces had been launching Operation Showdown against two targets: Triangle Hill and Sniper Ridge, northwest of Kunwha, north of the 38th Parallel. During the battle, the Chinese managed to amass 133 large caliber guns, 24 BM-13 rocket launchers and 47 anti-aircraft guns in the largest Chinese artillery operation during the Korean War, and it posed a serious threat to ground troops of the ROK 2nd Infantry Division operating in the area. The artillery was heavily guarded, forcing the UN forces to use airpower to combat them.

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 10 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 31 at Tolka Park on 5 January 1984 to lift the League of Ireland Cup. Gallagher returned to Wisbech Town for the 198485 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.
