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: Who was the ruler of South African mandate when it took over the South West Africa German colony? Passage 1:German Namibians () are a community of people descended from ethnic German colonists who settled in present-day Namibia. In 1883, the German trader Adolf Lüderitz bought what would become the southern coast of Namibia from Josef Frederiks II, a chief of the local Oorlam people, and founded the city of Lüderitz. The German government, eager to gain overseas possessions, annexed the territory soon after, proclaiming it German South West Africa (). Small numbers of Germans subsequently immigrated there, many coming as soldiers (), traders, diamond miners, or colonial officials. In 1915, during the course of World War I, Germany lost its colonial possessions, including South West Africa (see History of Namibia); after the war, the former German colony was administered as a South African mandate. The German settlers were allowed to remain and, until independence in 1990, German remained an official language of the territory alongside Afrikaans and English.
 Passage 2:Earle L. Reynolds (October 18, 1910 – January 11, 1998) was an anthropologist, educator, author, Quaker, and peace activist. He was sent to Hiroshima by the Atomic Energy Commission in 1951 to study the effects of the first atomic bomb on the growth and development of exposed children. His professional discoveries concerning the dangers of radiation later moved Reynolds into a life of anti-nuclear activism. In 1958 he sailed with his wife Barbara, two of his three children and a Japanese yachtsman in the Phoenix of Hiroshima, a ketch he had designed himself, into the American nuclear testing zone in the Pacific. In 1961 the family sailed to the USSR to protest Soviet nuclear testing. During the Vietnam War Reynolds and his second wife Akie sailed the Phoenix to Haiphong to deliver humanitarian and medical aid to victims of American bombing.
 Passage 3:The Anita Kerr Singers or The Jordanaires sang background on just about every Nashville hit in the late 1950s and early 1960s. After she and Al Kerr divorced, she disbanded the Nashville version of her Anita Kerr Singers and relocated to Los Angeles in August 1965 with her second husband, Swiss businessman Alex Grob, and her daughters Suzie & Kelly. She no longer wanted to just be a background singer or arranger on country songs – she wanted to do pop music, jazz and "do more orchestral writing and music that was not just country.". She hired some lawyers to get her out of her contract with RCA’s Nashville division, got a contract with Warner Bros. Records, and formed a Los Angeles version of the Anita Kerr Singers. The new group, for the next five years, would include the following personnel: alto B.J. Baker or Jackie Ward, tenor Gene Merlino or Bill Cole, baritone Bill Lee, bass Bob Tebow, and Kerr herself as soprano and arranger. The half dozen albums recorded by the Singers for Warner included a cover version of the song "All You Need Is Love" by The Beatles, and one of the LPs was exclusively devoted to the songs of composer Bert Kaempfert. Disguising the group as the Mexicali Singers, Kerr also recorded a trio of mariachi-flavored albums with musical arrangements reminiscent of the Herb Alpert & The Tijuana Brass sound. The Anita Kerr Singers won another Grammy Award for their recording of A Man And A Woman, released as a single on Warner Bros. Records.

Example Input: Question: In what year did the sketch that inspired the gravestone inscriptions in Plants vs. zombies first air on television? Passage 1:The track was performed during the Post Tour, a performance of which can be found on the 1998 live DVD/VHS Live at Shepherds Bush Empire, a fan-club only concert held at the end of the tour. To support the release of Post, the song was performed on the UK TV show Later... with Jools Holland on 17 June 1995 with legendary slide guitarist BJ Cole. This performance was featured on Björk's 2003 DVD release Later. Björk also performed the track on TFI Friday on 1 November 1996 to promote the official single release. The track was also included on a 1996 ChildLine charity album release, whose cover-art featured a parody of the Post cover. In support of this album, Björk performed the song on Top of the Pops. Björk's then manager Netty Walker noted later that it "was the worst performance I've ever seen her do." A live performance recorded for US TV show Reverb in 2001 included a performance of "Possibly Maybe". The track has been performed on Björk's subsequent tours, the Homogenic Tour and the Vespertine World Tour, the latter version of which appears on the 2002 DVD release Live at Royal Opera House. After 2001, the song was not performed live until March 2, 2012 at the Roseland Ballroom in New York City during her Biophilia Tour, using only a hang drum and a Tesla coil.
 Passage 2:Staying true to her love of music, Jayne's first dance music single "Roller Coaster" was released on January 1, 2007. The song placed at number one on the Billboard Hot Dance Club Play chart. Her second single “Stars” also placed at number one the Billboard Dance Play chart and music video for the song spent 12 weeks (peaking at number 2) on Logo TV’s . In 2007, British newspaper The Guardian wrote that Erika Jayne “is Madonna trapped in the moment when she recorded the Erotica album. She’s Nicole Kidman in Moulin Rouge goes trance with a dash of debauchery, or Gwen Stefani goes burlesque.” Jayne's debut full-length album Pretty Mess, was released in the United States on August 11, 2009. Sheila E. is found playing percussion on the song, “Time to Realize” and the album includes a cover of Apollonia 6’s 1984 hit “Sex Shooter.” Peter Rafelson and Eric Kupper served as producers and co-writers on Pretty Mess, while Canadian singer-songwriter Esthero, Jahi Lake and Ike Dirty contributed additional production. The other singles from the album were "Give You Everything" and "Pretty Mess", which topped the dance club charts. The album spawned a total of four number-one singles on the Hot Dance Club Play chart, tying her with Rihanna and The Pussycat Dolls for most number one singles from a debut release. She released three different music video versions of "Give You Everything". The music videos were directed by feature film director Marty Thomas. Remixes of "Give You Everything" placed at number 2 on the Music Week Upfront Club Chart as well as number 6 on the Music Week Commercial Pop Club Chart, marking her first time to land on the United Kingdom charts. Jayne supported the release of Pretty Mess with tour dates and appearances at festivals and clubs across the United States. In November 2010, Jayne announced the creation of her own record label, Pretty Mess Records.
 Passage 3:Plants vs. Zombies uses many cultural references in its names of stages and others. The gravestones' inscriptions ("Expired", "Ceased to Exist", "Just Resting", etc.) were taken from Monty Python's "Dead Parrot sketch". Three of the mini-games—"Zombiquarium", "Beghouled" and "Beghouled Twist"—take their names from two other PopCap games: Insaniquarium, Bejeweled and Bejeweled Twist respectively. Two levels in "vasebreaker" puzzles, "Scary Potter" and "Ace of Vase", take their names from Harry Potter and Ace of Base. Similarly, the "I, Zombie" (a reference to Isaac Asimov's "I, Robot") puzzles have levels called "Dead Zeppelin" (resembling Led Zeppelin) and "All your brainz r belong to us" (a play on the gaming meme "All your base are belong to us"). The name of the Torchwood plant is a reference to Doctor Who and its spin-off show Torchwood. Originally, the dancing zombie resembled Michael Jackson from the short film "Thriller". Though the Jackson-inspired zombie was present in the game before Jackson's death, the estate of Michael Jackson objected to its inclusion more than a year after his death; PopCap agreed to remove the Jackson-inspired zombie and replaced it with a more generic disco-dancing one for all future patches and releases of the game. A "disclaimer" in the game's almanac states "Any resemblance between Dancing Zombie and any persons living or dead is purely coincidental." Some Plants vs. Zombies advertisements parody controversial Evony ads, showing a drooling zombie instead of a voluptuous woman.
