Input: Consider Input: Question: How many NBA championships have been won by the team that Payton was traded to on February 24, 2005? Passage:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 2004–05 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

Input: Consider Input: Question: What year saw the publication of the eleventh edition of the zoological book published by a Swedish naturalist who included the hook-billed vanga in the twelfth edition of the book? Passage:In 1760 the French zoologist Mathurin Jacques Brisson included a description of the hook-billed vanga in his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name L'écorcheur de Madagascar and the Latin Collurio Madagascariensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the hook-billed vanga. Linnaeus included a brief description, coined the binomial name Lanius curvirostris and cited Brisson's work. It is now the only species placed in the genus Vanga that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. The specific name curvirostris is from Latin curvus "curved" and -rostrum "billed". The word "vanga" is the Malagasy name for the species. Two subspecies are recognised.

Input: Consider Input: Question: What date did the Volunteers lose 33-20? Passage:The 1997 Tennessee Volunteers football team represented the University of Tennessee during the 1997 NCAA Division I-A football season. Quarterback Peyton Manning had already completed his degree in three years, and had been projected to be the top overall pick in the 1997 NFL Draft, but returned to Tennessee for his senior year. The Volunteers opened the season with victories against Texas Tech and UCLA, but for the third time in his career, Manning fell to Florida, 33–20. The Vols won the rest of their regular season games, finishing 10–1, and advanced to the SEC Championship Game against Auburn. Down 20–7, Manning led the Vols to a 30–29 victory. Throwing for four touchdowns, he was named the game's MVP, but injured himself in the process. The #3 Vols were matched up with #2 Nebraska in the Orange Bowl. Had Tennessee won and top-ranked Michigan lost to Washington State in the Rose Bowl, the Vols would have been expected to win the national championship. However, the Vols' defense could not stop Nebraska's rushing attack, giving up more than 400 yards on the ground in a 42–17 loss. As a senior, Manning won numerous awards. He was a consensus first-team All-American and won the Maxwell Award, the Davey O'Brien Award, the Johnny Unitas Award, and the Best College Football Player ESPY Award, among others. However, he did not win the Heisman Trophy, finishing runner-up to Charles Woodson, a CB from Michigan, and the only defensive player ever to win the Heisman Trophy.
