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: What year did the Scramble for Africa begin? Passage 1:In 945, Bosenbach had its first documentary mention when Otto I, Holy Roman Emperor, granted his faithful follower Franko a few landholds. To better describe where these landholds lay, both Reichenbach and Bosenbach were named. Either Franko or his heirs yielded these lands shortly after 945 to Saint Maximin's Abbey in Trier. Until about 1100, Bosenbach was listed time and again as being among the monastery's holdings. Territorially, Bosenbach belonged to the Imperial Domain (Reichsland) around Kaiserslautern and about 1130, it came to be held as a Palatine fief by the Counts of Veldenz. About 1282, the Amt of Bosenbach (Bosenbach, Niederstaufenbach and Friedelhausen) was held in common ownership by the Counts of Veldenz and the Waldgraves. Later, in the 14th and 15th centuries, the common ownership had ended and it was owned by the Waldgraves and Rhinegraves (one group). In 1595, through territorial trade, the Amt found its way back into the Duchy of Palatinate-Zweibrucken. From the years 1514, 1537 and 1578 come three Weistumer dealing with Bosenbach (a Weistum cognate with English wisdom was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times; Weistumer is the plural).
Passage 2:The 1880s saw an intense competition between the European powers for territories in Africa, a process known as the Scramble for Africa. The process culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward. As a result of this France gained control of the upper valley of the Niger River (roughly equivalent to the areas of modern Mali and Niger). France had already conquered most of northern Algeria during the period 1830-47, incorporating it as an integral part of France. France occupied the area of modern Niger in 1900, declaring it a military territory, ruled originally from Zinder. Niger was originally included, along with modern Mali and Burkina Faso, within the Upper Senegal and Niger colony, however it was split off in 1911 and became a constituent of the federal colony of French West Africa (Afrique occidentale francaise, abbreviated AOF). In the meantime in Algeria France had been pushing south from the littoral region, conquering much of the Algerian Sahara in 1902. A boundary between French West Africa and French Algeria (i.e. what are now Algeria's borders with Mauritania, Mali and Niger) was agreed on 7 June 1905 by the Commandant of Upper Senegal and Niger and the Military Commander of the Department de l'Oasis within French Algeria. The border was further defined by the Niamey Convention of June 1909.
Passage 3:The discography of South Korean-born Australian recording artist Dami Im consists of five studio albums, two extended plays, ten singles, two album appearances, and four music videos. Im began her music career as a gospel singer in Korea and independently released her debut studio album, Dream, in 2010. She was the winner on the fifth season of The X Factor Australia in 2013, and subsequently received a contract with Sony Music Australia. Im released her self-titled second studio album in November 2013, which features selected songs she performed as part of the top twelve on The X Factor. The album debuted at number one on the ARIA Albums Chart and was certified platinum by the Australian Recording Industry Association (ARIA), denoting shipments of 70,000 copies. Additionally, the album also included Im's debut single "Alive", which topped the ARIA Singles Chart and was certified platinum. She became the first X Factor Australia contestant to follow up a number one single with a number one album on the ARIA Charts.

Example Input: Question: Who is the latest person to hold the position of the person Heder persuaded to borrow 40 silver denari? Passage 1:Sprigg joined the FRC in 2001, and his research and writing have addressed issues of marriage and family, human sexuality, and religion in public life, and opposition to same-sex marriage and gay rights. He has testified before federal, state and local courts on these issues. He has argued that gay marriage is not an issue of civil rights. He has linked homosexuality to pedophilia, and argued that homosexuals are trying to brainwash children into accepting homosexuality through public schools. Sprigg has publicly suggested that repealing Don't Ask, Don't Tell would encourage molestation of heterosexual members of the military and suggested Kevin Jennings may have engaged in statutory rape. In February 2010, Sprigg stated on NBC's Hardball that Lawrence v. Texas was wrongly decide by the U.S. Supreme Court and that "criminal sanctions against homosexual behavior" should be enforced; FRC President Tony Perkins later declared that criminalizing homosexuality is not a goal of the Council.
Passage 2:Impressing at non-league Halifax Town, he turned professional with Doncaster Rovers in 2005. Used sparingly in 200506, he was loaned out to Oxford United in March 2006, though did not make it onto the pitch. In 200607 he was loaned out to Darlington and Stafford Rangers, before he spent the 200708 campaign on loan at Halifax Town. In April 2008 he signed with Port Vale, and became a first team regular in 200809. He remained a key first team figure in 200910 and 201011, and was voted the club's Player of the Year in 2010. He continued to impress for the "Valiants", and earned a move up a division to Leyton Orient in May 2012. He returned to Port Vale on loan in March 2013, and helped the club to secure promotion out of League Two in 201213, before re-joining on a permanent basis in the summer. He signed with Shrewsbury Town in August 2014, before moving on to Carlisle United in January 2015. Six months later he signed for Altrincham before retiring in September 2015 due to a hip injury. He came out of retirement to sign for Glossop North End in September 2016. In 2017 he played for Trafford, Colwyn Bay, and Congleton Town.
Passage 3:Between 1150 and 1158, Heder held the dignity of Judge royal, the second-highest secular position after the Palatine. In this capacity, he persuaded Raphael, the abbot of Pannonhalma to borrow 40 silver denari to the king, who planned to visit Henry II, Duke of Austria with his court and a large number of escorts. Raphael had to sell a church estate in order to obtain sum. When Geza invaded the Byzantine Empire and laid siege to Branicevo in late 1154, plausibly Heder and his brother also participated in the campaign alongside other German knights, as Greek historian John Kinnamos referred to them "Saxon" mercenaries. In fear of being seized and executed by King Geza II, his brother, the rebellious Duke Stephen sought refuge in the Holy Roman Empire in the summer of 1157. Frederick I, Holy Roman Emperor, was willing to arbitrate the conflict between Geza II and Stephen, and dispatched his envoys to Hungary. In response, Geza sent delegates to the Emperor, Judge royal Heder and Gervasius, Bishop of Gyor. At the Diet of Regensburg in January 1158, Heder and Gervasius rejected the accusations of Stephen and successfully reached the Emperor withdrew his support from the pretender. After that Stephen left for Constantinople.

Example Input: Question: Which TLC hit that reached top 10 on the UK Singles Chart was the most successful commercially? Passage 1:The Very Best of TLC: Crazy Sexy Hits material is taken from four of their studio albums: Ooooooohhh... On the TLC Tip (1992), CrazySexyCool (1994), FanMail (1999), and 3D (2002), and Now & Forever: The Hits (2003), which were all recorded from 1991 to 2003. Their 1993 cover of The Time's "Get It Up" for the soundtrack to Poetic Justice does not appear on any of their studio albums, but still appears on the compilation along with the trio's most successful singles in the United Kingdom. These include "No Scrubs", which placed at number three on the UK Singles Chart and was awarded a platinum certification from the British Phonographic Industry (BPI); "Waterfalls", which peaked at number four on the UK Singles Chart and also achieved platinum status; "Unpretty", a silver-certificated single which peaked at number six on the UK Singles Chart, and "Creep", which also peaked at number six on the UK Singles Chart after being reissued across the UK and Europe. It did not, however, include "Dear Lie", a moderately received UK single which was certified silver. Instead, the non-charting songs "Come Get Some", "Damaged" and "Get It Up" were included in the final track listing, with "Whoop De Woo" (a non-album track) and "In Your Arms Tonight" (from 3D) the only two non-single tracks that appeared the compilation.
Passage 2:Casillas began his career in Real Madrid's youth system, known as La Fabrica, during the 199091 season. On 27 November 1997, at age 16 and still a junior, he was first called up to the senior team squad to face Rosenborg in the UEFA Champions League, although he remained on the bench throughout. After spending a season with the C-team in the fourth tier, during which they won their regional group, he came into contention as the club's first-choice between the posts. In starting the 19992000 UEFA Champions League group stage fixture against Olympiakos on 15 September 1999, he became the youngest goalkeeper ever to feature in the competition at the time, aged 18 years and 177 days; a record which was only broken in October 2017 by Mile Svilar. Three days earlier, Casillas had made his La Liga debut in a 22 draw against Athletic Bilbao at San Mames Stadium. In May 2000, he became the youngest ever goalkeeper to play in and win a Champions League final when Real Madrid defeated Valencia 30, just four days after his 19th birthday.
Passage 3:On 21 November, Vale picked up their third league win of the campaign, beating lowly Barnsley 20 at Oakwell. Youth players continued to be drafted in as Vale finished the year with four straight league defeats, picking up injuries and sendings off along the way. In December, Hancock was sold to Ipswich Town for 10,000. A 21 victory over promotion-chasers Brentford on 2 January failed to spark a revival, partly due to the fact that the Bees were forced to play almost the entire match with ten players and an outside player in goal following an injury to Chic Brodie. Steele tried to play a settled team, but that proved to be as unsuccessful as when he switched the team round constantly. By the end of the month the club were bottom of the league and morale was low. In mid-February, the club four points short of safety, Steele left the club 'by mutual consent', as Jackie Mudie was appointed caretaker manager. Following a 40 hammering from Gillingham, Mudie signed veteran stopper Jimmy O'Neill from Darlington, and the former Ireland international seemed to improve the team, as just two defeats in eight games followed. Mudie instilled discipline into the team, and so was made manager on a permanent basis on 3 March. He then ensured Reg Davies was transferred to Leyton Orient. He tried and failed to re-sign Terry Harkin from Crewe Alexandra. One win in their final six games doomed the Vale to relegation, just as survival seemed possible. Only 3,521 witnessed a final day victory over Walsall.
