Example Input: Question: Which university's football team that Bradford played against after his return had a better 2009 season record? Passage:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (5–3 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 40–14, and in 1993, they defeated Texas Tech 41–10.

Example Input: Question: Has any of the teams Leadbitter rode for between 1966 and 1968 won a championship? Passage:Born in Lichfield, Staffordshire, Leadbitter was a successful grasstrack racer before taking up speedway in 1966 at the training school at Long Eaton. After a single match for Glasgow Tigers in 1966 he rode in four matches for Long Eaton Archers in 1967. In 1968 he was signed by newly formed Leicester Lions, but only made one appearance for the team that season, spending most of it on loan to Middlesbrough Teessiders. In 1969 he progressed with Middlesbrough, averaging close to nine points per match, and had rode in four matches in the top division as a guest for Newcastle Diamonds. In 1970 he stayed with Middlesbrough as well as riding in several matches for his parent club Leicester, and was recalled to a full team place for the Lions in 1971. He competed in the Second Division Riders Championship in 1970, finishing in fifth place. At the end of the season he transferred to Wolverhampton Wolves where he spent four seasons, establishing himself as a solid scorer, although in 1975 his rides for Wolves were limited and he returned to Teesside in the National League where he averaged over nine points and recorded five full maximum and three paid maximum scores in 33 matches. After a second season back with Teesside in 1976 he moved on to Bristol Bulldogs in 1977, his final season before retiring.
