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: In what year did Hellhammer become Celtic Frost? Passage 1:Welcome to Hell influenced several later bands. Venom's music helped shape the development of many thrash metal bands, specifically the "Big Four of Thrash" (who in turn were highly influential): Metallica, Slayer, Anthrax, and Megadeth (Metallica opened for Venom on an early 1980s tour, and Venom opened for Metallica and Slayer on the Ride the Lightning tour, and Slayer played with them and Exodus on the Combat Tour in 1985). Venom would also be of extreme importance to the black metal scene and even the early death metal scene, with numerous bands copying styles, themes, and imagery from the band, such as the Swiss band Hellhammer (later to become Celtic Frost), whom also helped pioneer the genres. Music critic Bradley Torreano wrote that Venom "caught the attention of both metalheads and punks, the band was emulated by the former and turned into camp icons by the latter." Henry Rollins once compared the band to Spinal Tap.
 Passage 2:Duncan was born in Lebanon, Tennessee. His "paternal grandparents were small-areage farmers in Scott County, which in 1861 left Tennessee, refusing to follow the Volunteer State into the Confederacy, and declared itself 'the Free and Independent state of Scott.'" Duncan's parents were Lois (Swisher) and John Duncan Sr., who "hitchhiked into Knoxville with five dollars in his pocket,' and after an education at the University of Tennessee was elected mayor of Knoxville and then congressman." The elder Duncan was also a co-owner of the Knoxville Smokies of the "Sally League," for which his son "was a batboy, a ball shagger, scoreboard operator, and, as a freshman at the University of Tennessee, the Smokies' public-address announcer." Duncan also worked as a grocery bagger and salesman at Sears while working his way through school. Duncan supported Barry Goldwater's 1964 presidential campaign, and sent the first paycheck he earned as a bagboy at the local A&P to the Goldwater campaign.
 Passage 3:Lynch first came to prominence on the inter-county scene as a member of the Cork senior football team in the late 1990s. He made his debut in the 1998–99 National Football League, a season which saw Cork reach the final of the competition. Dublin provided the opposition at Cork's home venue, Páirc Uí Chaoimh. A close game developed, however, Cork were never really troubled. A 0–12 to 1–7 score line resulted in victory for 'the Rebels', and gave Lynch a National League winners' medal in his debut season. Later that year he made his championship debut in the provincial series as Cork cruised to a Munster final showdown with arch-rivals Kerry. The men from 'the Kingdom' were on the hunt for a fourth successive provincial title, while Cork were out for success for the first time since 1995. Cork's victory on a score line of 2–10 to 2–4 was unexpected as Lynch claimed his very first Munster winners' medal. A subsequent defeat of Mayo saw Cork book their place in the All-Ireland final against Meath. The pressure was on the Cork footballers to secure a rare double, particularly since their hurling counterparts had won the All-Ireland title a fortnight previously. Ollie Murphy's first-half goal gave 'the Royals' a huge boost at half-time. Immediately after the interval Trevor Giles missed a penalty while Joe Kavanagh responded with a goal which gave Cork a brief lead. It was not enough as Lynch's side eventually lost the game by 1–11 to 1–8. In spite of this defeat Lynch was later rewarded with an All-Star award.

Example Input: Question: When was the Good Friday Agreement established? Passage 1:He testified as an expert witness about Russian interference in the 2016 United States elections, in a March 30, 2017 hearing before the United States Senate Select Committee on Intelligence. His testimony before the Senate Intelligence Committee was well received, and made multiple headlines. Slate referred to him in a headline as: "Clint Watts, Testifier Extraordinaire", and "The star of March’s Senate Intelligence Committee hearing". CNN profiled him after the testimony in a piece "Russia investigation: Who is Clint Watts", where it was noted he gained knowledge in the field of Russian cyber hacking methods, after himself being a target in 2015 following his "Trolling for Trump" article; the FBI notified the Foreign Policy Research Institute of the attack. Salon compared his testimony "follow the trail of dead Russians" to John Dean's statement about "a cancer on the presidency". This phrase in testimony by Watts was highlighted by the media, including CBS News, The American Interest, and The Oregonian. U.S. Senator Ron Wyden found the comment important to his investigation. Mark Shields of PBS NewsHour found his testimony "compelling", and CNN called it "blistering". Jennifer Rubin wrote for The Washington Post that his testimony "laid out the most comprehensive look at the array of tools Russia used to influence our election". After his testimony, he appeared on NBC's Meet the Press and explained ways the U.S. can better respond to cyberwarfare.
 Passage 2:The Irish government under outgoing Taoiseach Enda Kenny expressed concerns that a parliamentary deal between a British government and the DUP could put the Northern Ireland peace process at risk, a view also expressed by Sinn Féin politicians Gerry Adams and Gerry Kelly, Labour MP Yvette Cooper and former Downing Street Director of Communications Alastair Campbell. This opinion was, however, rejected by the Conservative leadership and former Secretary of State for Northern Ireland, Theresa Villiers, as well as by former Labour minister Caroline Flint who suggested that Gordon Brown may have sought an agreement with the DUP in 2010. The Conservative peer and former UUP First Minister of Northern Ireland, David Trimble, described claims that an agreement would put the peace process at risk as "scaremongering". On 13 June former Conservative Prime Minister John Major publicly urged May to govern without DUP support and not pursue a deal, on the grounds that an agreement could "damage" the "fragile" Northern Ireland peace process, suggesting the government must remain 'impartial'. Major himself had an agreement with the Unionist MPs of the UUP when in power and during peace negotiations in Northern Ireland, though not with the more hardline and socially-conservative DUP. On 15 June Sinn Féin's Gerry Adams met with Theresa May, telling her that he thought she was in breach of the Good Friday Agreement. This has been disputed by one of the UUP's negotiators for the Belfast Agreement.
 Passage 3:Since 1995, 69 commercial video games based on Lego, the construction system produced by The Lego Group, have been released.

The division also co-published with Electronic Arts before closing. Former Lego Interactive staff founded company Giant Interactive Entertainment for future Lego game publishing. Following the release of , Giant merged with Traveller's Tales to form TT Games. TT Games was acquired by Warner Bros. Interactive Entertainment (WBIE) in November 2007, making WBIE the primary publisher for Lego games.

Example Input: Question: In what year was the university established where Friedrich Hornemann studied Arabic. Passage 1:Hornemann was born in Hildesheim, a city in Lower Saxony, Germany, located about 30 km southeast of Hannover. He was a young man when, early in 1796, he offered his services to the African Association of London as an explorer in Africa. The African Association sent him to the University of Göttingen to study Arabic and otherwise prepare for an expedition from the east into the unknown regions of North Africa. In September 1797 he arrived in Egypt, where he continued his studies. When the country was invaded by the French, he was confined in the citadel of Cairo to preserve him from the fanaticism of the populace. Liberated by the French, he received the patronage of Bonaparte. On 5 September 1798 he joined a caravan returning to the Maghreb from Mecca, attaching himself to a party of Fezzan merchants who accompanied the pilgrims. As an avowed Christian would not have been permitted to join the caravan Hornemann assumed the character of a young mamluk trading to Fezzan. He then spoke, but indifferently, both Arabic and Turkish, and he was accompanied as servant and interpreter by Joseph Freudenburg, a German convert to Islam, who had thrice made the pilgrimage to Mecca. Travelling by way of the oases of Siwa and Aujila, a black rocky desert was traversed to Temissa in Fezzan. Murzuk was reached on 17 November 1798.
 Passage 2:Smith played four years at San Jose State University and had 13 career interceptions, the second-most in school history. He joined the team as a walk-on in 1995 and was assigned to cover Keyshawn Johnson in his first collegiate start. He led San Jose State with nine passes broken up in 1996 and 16 in 1997. He tied for second in the nation in 1997 with seven interceptions and tied a school record with three interceptions against the University of Hawaii. Smith returned 22 punts for 246 yards and was the only player in Division I-A to rank in the top-30 in both interceptions and punt returns. He had an 84-yard touchdown return at UTEP in 1997 and an 88-yard punt return for a touchdown against Fresno State in 1998. Smith had 74 tackles as a sophomore, third-most on the team, and ended his career with 182 career tackles.
 Passage 3:Underwater hockey (UWH), also known as Octopush (mainly in the United Kingdom) is a globally played limited-contact sport in which two teams compete to manoeuvre a puck across the bottom of a swimming pool into the opposing team's goal by propelling it with a hockey stick (pusher). It originated in England on November 18 1954 when Alan Blake, a founder of the newly formed Southsea Sub-Aqua Club, invented the game he called Octopush as a means of keeping the club's members interested and active over the cold winter months when open-water diving lost its appeal. Underwater hockey is now played worldwide, with the Confédération Mondiale des Activités Subaquatiques, abbreviated CMAS, as the world governing body. The first Underwater Hockey World Championship was held in Canada in 1980 after a false start in 1979 brought about by international politics and apartheid.
