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: Was Commandino older or younger than Francesco Maurolico? Passage 1:In 1787, Swedish part-time chemist Carl Axel Arrhenius found a heavy black rock near the Swedish village of Ytterby, Sweden (part of the Stockholm Archipelago). Thinking that it was an unknown mineral containing the newly discovered element tungsten, he named it ytterbite. Finnish scientist Johan Gadolin identified a new oxide or "earth" in Arrhenius' sample in 1789, and published his completed analysis in 1794; in 1797, the new oxide was named yttria. In the decades after French scientist Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. Until the early 1920s, the chemical symbol "Yt" was used for the element, after which "Y" came into common use. Yttrium metal was first isolated in 1828 when Friedrich Wohler heated anhydrous yttrium(III) chloride with potassium to form metallic yttrium and potassium chloride.
Passage 2:Aikido was first brought to the rest of the world in 1951 by Minoru Mochizuki with a visit to France where he introduced aikido techniques to judo students. He was followed by Tadashi Abe in 1952, who came as the official Aikikai Hombu representative, remaining in France for seven years. Kenji Tomiki toured with a delegation of various martial arts through 15 continental states of the United States in 1953. Later that year, Koichi Tohei was sent by Aikikai Hombu to Hawaii for a full year, where he set up several dojo. This trip was followed by several further visits and is considered the formal introduction of aikido to the United States. The United Kingdom followed in 1955; Italy in 1964 by Hiroshi Tada; and Germany in 1965 by Katsuaki Asai. Designated "Official Delegate for Europe and Africa" by Morihei Ueshiba, Masamichi Noro arrived in France in September 1961. Seiichi Sugano was appointed to introduce aikido to Australia in 1965. Today there are aikido dojo throughout the world.
Passage 3:Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (On the sizes and distances of the Sun and the Moon), Pappus of Alexandria (Mathematical collection), Hero of Alexandria (Pneumatics), Ptolemy of Alexandria (Planisphere and Analemma), Apollonius of Perga (Conics) and Euclid of Alexandria (Elements). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The proposition known as Commandino's theorem first appears in his work on centers of gravity.

Example Input: Question: Which of the performers during the ceremony was the oldest at the time of the ceremony? Passage 1:Born in Bedford on 22 September 1780, John Hensman was educated at Bedford School and at Corpus Christi College, Cambridge, where he matriculated as an Exhibitioner in February 1797. He graduated as ninth Wrangler at the University of Cambridge in 1801 and was elected as a Fellow of Corpus Christi College, Cambridge. He was ordained in 1803, and was appointed as Curate of Wraxall, Somerset. In 1809 he was appointed as Curate of Clifton, Bristol. He was instrumental in the rebuilding of Clifton parish church, which was consecrated on 12 August 1822. He was then the moving force behind the building of the Church of Holy Trinity, Hotwells, which was consecrated on 10 November 1830. He held the incumbency of the church until 1844, when he was granted the perpetual curacy of Christ Church, Clifton Down, and he oversaw the rebuilding of that church. He was instituted to the living of Clifton, Bristol, in 1847, and oversaw the building of St Paul's Church, Clifton, Bristol, consecrated in 1853, and St Peter's Church, Clifton, consecrated in 1855.
Passage 2:Ngawang Drakpa Gyaltsen was the son of Drowai Gonpo (15081548), a sub-ruler who resided in Gongri Karpo to the south-west of Lhasa. His grandfather was Ngawang Tashi Drakpa (14881564), the last effective king of the Phagmodrupa line. The main palace of the dynasty was Nedong southeast of Lhasa. In 1554 Ngawang Drakpa Gyaltsen temporarily took over the throne of his old grandfather, when the latter was forced to step down for a while. However, new turmoil broke out in Central Tibet in 1555. A council was headed by the religious hierarchs of Drigung Kagyu and Shamarpa, and it was decided to put the old ex-king back on the throne. Ngawang Drakpa Gyaltsen had to return to Gongri Karpo. Some years later he rose against the 75-year-old ruler and tried to acquire the throne permanently. He was aided in his ambitions by the ruler of Ganden. He also kept good relations with Sonam Gyatso, later known as the Third Dalai Lama. A number of Buddhist dignitaries tried to intervene in the rebellion, to no avail. In the next year 1564, his grandfather died. New disturbances broke out between the Nedong and Gongri Karpo branches of the dynasty. Sonam Gyatso was asked to mediate in the conflict. Eventually Ngawang Drakpa Gyaltsen became the new gongma or king in 1576. However, the executive authority of the Phagmodrupa was now almost depleted. Nevertheless, the Phagmodrupa still filled a role as a focal point around which politics in U (East Central Tibet) revolved and different groups balanced each other. Conditions in this part of Tibet tended to be relatively peaceful in the decades of the late sixteenth century, and relations between the main religious sects Karmapa and Gelugpa were amiable for the moment.

Example Input: Question: How long had A&M Records been in business at the time the Carpenters signed a contract with them? Passage 1:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.
Passage 2:The 1966 NASCAR season opened at Augusta Speedway on November 14, 1965, with Richard Petty winning the season opening event in a 1965 Plymouth. NASCAR then ventured to Riverside International Raceway where Dan Gurney took the checkered flag in a 1965 Ford. After the January 23rd Riverside event, the drivers and teams traveled to Daytona International Speedway in Florida for the 1966 Daytona 500. Paul Goldsmith and Early Balmer took the qualifying events, while Richard Petty notched his first and only Daytona 500 pole position. Petty came from two laps down during the competition to win by more than a full lap when the race was halted 2 laps shy of scheduled event due to thunderstorms. In March Paul Goldsmith won at Rockingham Speedway, Dick Hutcherson at Bristol, and Jim Hurtubise captured the checkered flag at Atlanta Motor Speedway. Hutcherson's victory at Bristol was by more than 4 laps over the closest competitor, Paul Lewis, when crashes and attrition left only seven cars of the 38 starters running at the end of the Southeastern 500 (now known as Food City 500). On April 3, Pearson finally found his way to victory lane in the first of four consecutive victories at Hickory Motor Speedway. He followed up with wins at Columbia Speedway, Greenville, and Winston-Salem, before Jim Paschal broke his streak at North Wilksboro and repeated at Martinsville Speedway. On May 7, Richard Petty started a string of three consecutive wins at Darlington Raceway, Hampton, and Macon. After Ford's announcement of their boycott of NASCAR on April 7, only 2.500 fans attend the May 13th event in which Darel Dieringer captures the win at Monroe in a contest.
Passage 3:Born in Lichfield, Staffordshire, Leadbitter was a successful grasstrack racer before taking up speedway in 1966 at the training school at Long Eaton. After a single match for Glasgow Tigers in 1966 he rode in four matches for Long Eaton Archers in 1967. In 1968 he was signed by newly formed Leicester Lions, but only made one appearance for the team that season, spending most of it on loan to Middlesbrough Teessiders. In 1969 he progressed with Middlesbrough, averaging close to nine points per match, and had rode in four matches in the top division as a guest for Newcastle Diamonds. In 1970 he stayed with Middlesbrough as well as riding in several matches for his parent club Leicester, and was recalled to a full team place for the Lions in 1971. He competed in the Second Division Riders Championship in 1970, finishing in fifth place. At the end of the season he transferred to Wolverhampton Wolves where he spent four seasons, establishing himself as a solid scorer, although in 1975 his rides for Wolves were limited and he returned to Teesside in the National League where he averaged over nine points and recorded five full maximum and three paid maximum scores in 33 matches. After a second season back with Teesside in 1976 he moved on to Bristol Bulldogs in 1977, his final season before retiring.
