In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Example Input: Question: Where was Thomas Kenan's great grandfather born? Passage 1:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.
 Passage 2:A second battalion was raised in 1804 to increase the strength of the regiment. The 1st battalion embarked for Copenhagen in July 1807 and saw action at the Battle of Copenhagen in August 1807 during the Gunboat War before returning home in November 1807. It then embarked for Portugal in May 1808 for service under General Sir Arthur Wellesley in the Peninsular War and saw action at the Battle of Roliça in August 1808 and the Battle of Vimeiro later that month. In January 1809 the battalion took part in the Battle of Corunna, carrying out successive bayonet charges to keep the French at bay to which General Sir John Moore shouted "Well done, 50th! Well done, my Majors!". The battalion was subsequently evacuated from the Peninsula. Both battalions then embarked from the Downs in July 1809 and saw action in the disastrous Walcheren Campaign. It was the last regiment to leave Holland in December 1809.
 Passage 3:Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.

Example Input: Question: What year was the college Henry Hirst went to founded? Passage 1:Martin Guptill was ruled out of New Zealand's limited-overs squads due to injury. Glenn Phillips replaced him for the T20I match and Dean Brownlie replaced him for the ODI matches. However, ahead of the fourth ODI, Guptill and Jeetan Patel were added to the ODI squad and Matt Henry was released. However, ahead of the fifth ODI, Matt Henry was added back to the ODI squad. Ross Taylor was ruled out of the New Zealand squad for the 2nd Test due to calf injury sustained during the 1st Test. Neil Broom was named as his replacement. Matt Henry was also included in the Test squad. Dane Piedt was added to South Africa's squad ahead of the second Test. With Piedt added to South Africa's squad, Chris Morris was released from the team. Trent Boult was ruled out of New Zealand's squad for the 2nd Test due to leg injury sustained during the 1st Test. Duanne Olivier was released from South Africa's squad ahead of the third Test. Tim Southee was ruled out of the final Test with a hamstring injury.
 Passage 2:Hirst was born in 1838 in Huddersfield, Yorkshire, England. He received his education at Huddersfield College. He arrived at Port Chalmers in Otago on the Agra on 30 October 1858 and first settled in the Te Anau / Manapouri area in Southland. Together with John Charles Watts-Russell of Christchurch, he explored Breaksea Sound for open land for sheep farming, but they were unsuccessful in this venture. Next, Hirst settled at Riverton where he had a butchery. In 1860, he married a daughter of William Dallas. In August 1861, he was the first who managed to drive cattle from Southland to the Gabriel's Gully gold field during the Otago Gold Rush. Some time later, Hirst was farming at Orepuki. When gold was discovered in the locality in 1866, the government resumed the land that he was farming, and he bought another property in the town where he lived for the rest of his life.
 Passage 3:The Tigers improved again in the 1980–1981 season. In fact, it would be the winningest year in LSU history. This year, Dale Brown took his team to the Final Four, the second in LSU history, and the first of the Dale Brown era. The team finished 31–5 (most wins in the nation) and won the conference championship with a 17–1 record. The team also set a school record winning 26 straight games, including its first 17 conference games and the only SEC team to ever win 17 consecutive league games in the same season with only a loss to powerhouse Kentucky in Rupp Arena stopping LSU from becoming the only team to complete an 18-game SEC slate with an unblemished mark. Rudy Macklin was an All-American, as well as First Team All SEC. Ethan Martin also made First Team All SEC, and Howard Carter made the Second Team. LSU advanced to the Final Four by beating Wichita State 96–85 in the Elite 8 round of the 1981 NCAA tournament, played in front of home-state fans in the Louisiana Superdome. To reach the regional final, LSU defeated future SEC rival Arkansas, coached at the time by Eddie Sutton, who would tangle with Brown for four seasons at Kentucky.

Example Input: Question: What time period did the Byzantine Empire rule? Passage 1:American rapper Tyga has released seven studio albums, three compilation albums, nineteen mixtapes, seventy-four singles (including thirty-four as a featured artist) and forty-six music videos. In 2008, Tyga released his first studio album, No Introduction, on the record label Decaydance Records. The album featured the single "Coconut Juice", which features singer Travie McCoy; the song peaked at number 94 on the US Billboard Hot 100, becoming Tyga's first song to appear on the chart. In 2010, Tyga and American singer Chris Brown released the collaborative mixtape Fan of a Fan, which included the single "Deuces": the song peaked at number 14 on the Billboard Hot 100 and became Tyga's first song to chart on the US Hot R&B/Hip-Hop Songs chart, peaking at number one. Tyga also appeared on the song "Loyalty", a single by fellow rapper Birdman, and collaborated with rapper Lil Wayne on the non-album single "I'm on It", both of which failed to chart on the Billboard Hot 100.
 Passage 2:When Boris I assumed the throne of Bulgaria in 852, the country was still pagan, with the ruling Bulgar elite being Tengriists while the Slavic population practised its own religion. Christianity was already widespread in Bulgaria as the country was established on former territories of the Byzantine Empire, and seems to have been influential. Even one of the sons of Khan Omurtag (r. 814–831), Enravota, converted to Christianity. The Bulgarian nobility was strongly opposed to any form of Byzantine influence in the country and was therefore hostile to Christianity as it was directly associated with the Byzantine Empire. Boris I, however, had many reasons to consider conversion — Bulgaria was situated between two powerful Christian empires, Byzantium and East Francia; Christian doctrine particularly favoured the position of the monarch as God's representative on Earth; and finally, Boris also saw Christianity as a way to overcome the differences between Bulgars and Slavs. The geopolitical situation in the mid 9th century was also favourable because of the increasing friction and rivalry between the Papacy in Rome and the Ecumenical Patriarchate of Constantinople for influence in Central Europe. That struggle between the two churches would give the Bulgarian ruler the opportunity to manoeuvre and negotiate with both, thus extracting favourable concessions while keeping the country out of direct foreign influence. When the Byzantines invaded Bulgaria in the autumn of 863 and demanded conversion to Christianity from Constantinople as the single condition to retreat, Boris I readily accepted and was baptised in the beginning of 864, assuming the Christian name Michael after his spiritual godfather, the Byzantine Emperor Michael III. That step was very unpopular among the nobility, but when they rebelled Boris I dealt decisively with them and executed 52 magnates along with their whole families. When in the following year the Byzantines sturdily demonstrated their determination not to allow the existence of an autocephalous Bulgarian Church, Boris I decided to turn to the Papacy.
 Passage 3:At the end of the 2007–08 season, Humphreys was voted Player of the Year, Player of the 2000s and Hartlepool United's Player of the Century. He continued to be a key player in 2008–09, making a total of 54 appearances. He was a key figure once again in the 2009–10 season, missing just nine matches as a central midfielder. On 26 February 2011, Humphreys replaced Joe Gamble after 82 minutes to make his 473rd appearance for "Pools". This broke the record previously held by Watty Moore for over half a century. Over the course of the 2010–11 season he played 29 matches. On 2 August 2011, Humphreys was given a testimonial match against Premier League Sunderland to mark his ten years at Hartlepool United. Sunderland won 3–1, though the 5,757 fans present at the Victoria Park were reported to be very vocal in their appreciation of the veteran player. On 7 January 2012, Humphreys replaced Luke James 90 minutes into a 2–0 win over Rochdale to make his 500th appearance for "Pools". He signed an "undisclosed extension to his contract" in May 2012. He made 33 appearances in the 2012–13 campaign, as Hartlepool were relegated into League Two, though Humphreys was named on the League One team of the week after scoring in a 3–2 win at Sheffield United on 29 December.
