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 is the current population of the town where Benton first began to practice after completing the bar in 1835? Passage 1:Duchenne muscular dystrophy (DMD) is caused when a mutation in the dystrophin gene changes the RNA so that it no longer codes for functional dystrophin protein. This usually happens due to a mutation that alters the reading frame of the RNA downstream of the mutation, so-called frameshift mutation. If an exon with an appropriate number of bases lies near the mutation, removing that exon can correct the downstream reading frame, restoring the production of partially functional dystrophin. This is the general strategy used in the design of exon-skipping oligonucleotides for DMD. As there are 79 exons in the longest splice form of the dystrophin transcript, many different oligonucleotides are needed to address the range of mutations present in the population of people with DMD.
 Passage 2:Born in Fryeburg, Oxford County, Maine, Benton was the son of Dr. Joseph and Catherine Benton and the brother of Nathaniel S. Benton. He pursued preparatory studies before moving to Herkimer County, New York in 1824 to live with an elder brother. Later, he attended Lowville Academy at Lowville, New York. Benton also learned the tanner’s trade, but left the trade and became the editor of the Mohawk Courier and the Little Falls Gazette from 1830 to 1832. During that time he also studied law and was admitted to the bar in 1835 and commenced practice at Little Falls, New York. He married Emeline Fuller in 1840 and they had one son, Linn Boyd Benton (named for his colleague Linn Boyd), who became an inventor and engineer, and co-founded the printing company American Type Founders. Linn Benton's son (and Charles's grandson), Morris Fuller Benton, would become one of the most prolific American type designers of his era through his work for ATF. He married again in 1853 to Elizabeth B. Reynolds and they also had one son, Charles R. Benton.
 Passage 3:In February 2009, the band toured Europe; a number of the U.K. dates were part of a package tour sponsored by Metal Hammer dubbed "Defenders of the Faith" featuring Dimmu Borgir as co-headliners. The group then toured Australia through March as part of the Soundwave Festival, which was headlined by Nine Inch Nails and Alice in Chains. In April 2009, the group began a headlining North American tour, sponsored by No Fear Energy. The leg began in Phoenix, Arizona and wrapped up mid-May in North Myrtle Beach, South Carolina. In July 2009, during a European summer tour, guitarist Mark Morton exited the tour prior to the final six dates as he and his wife were expecting their first child. Morton was replaced by Buz McGrath of Unearth for the remaining summer dates, and Doc Coyle of God Forbid for.the first three weeks of a fall North American leg. Morton eventually rejoined the group in October in Tampa, Florida.

Example Input: Question: What was the combined age of Liu and his oath brothers when they took the Oath of the Peach Garden? Passage 1:Liu Bei and his oath brothers Guan Yu and Zhang Fei swore allegiance to the Han Empire in the Oath of the Peach Garden and pledged to do their best for the people. However, their ambitions were not realised as they did not receive due recognition for helping to suppress the Yellow Turban Rebellion and participating in the campaign against Dong Zhuo. After Liu Bei succeeded Tao Qian as the governor of Xu Province, he offered shelter to Lü Bu, who had just been defeated by Cao Cao. However, Lü Bu betrayed his host, seized control of the province and attacked Liu Bei. Liu Bei combined forces with Cao Cao and defeated Lü Bu at the Battle of Xiapi. Liu Bei then followed Cao Cao back to the imperial capital, Xu, where Emperor Xian honoured him as his "Imperial Uncle". When Cao Cao showed signs that he wanted to usurp the throne, Emperor Xian wrote a secret decree in blood to his father-in-law, Dong Cheng, and ordered him to get rid of Cao. Dong Cheng secretly contacted Liu Bei and others and they planned to assassinate Cao Cao. However, the plot was leaked out and Cao Cao had Dong Cheng and the others arrested and executed along with their families.
 Passage 2:The most dramatic match came in the qualifying rounds when Terry Griffiths, a newly turned professional was beaten 8–9 by Rex Williams after leading 8–2. The championship proper also provided plenty of surprises. Patsy Fagan, the defending UK champion went out 7–9 in the first round to David Taylor who, after a decade in the professional ranks, reached his first major final by beating Alex Higgins 9–5 in the semi-final. In the other half, Roy Andrewartha beat John Spencer 9–8 and Willie Thorne beat Ray Reardon 9–6 only to collapse 1–9 against Graham Miles, whose 139 break set a tournament record. In the semi-finals it was Miles' turn to collapse 1–9 to Doug Mountjoy who, keeping his best till last, clinched his final victory over Taylor with a break of 120. The BBC televised the final again shown on Grandstand and with Ted Lowe commentating the match. The highest break of the tournament was 139 made by Graham Miles.
 Passage 3: arena was the site of several historic sporting events, including the professional debut of Sonja Henie, fresh from her triumph in the 1936 Winter Olympics. Roy Rogers, cowboy movie star, performed in his first rodeo at the Philadelphia arena in 1943. The Roy Rogers Rodeo played the Arena every season for more than 20 years, and in 1946, when a young cowgirl died after riding a bucking bronco, her funeral was held there. Rogers and the Sons of Pioneers sang "Roundup in the Sky", and after the closing prayer, everybody rode out to the cemetery. It was also the home of the Philadelphia Sports Writers Association Banquet. Professionally, the arena was the home of the Philadelphia Quakers of the NHL in their only season, 1930–1931, as well as home ice for several minor league hockey teams such as the Philadelphia Arrows, Philadelphia Ramblers, the Philadelphia Comets, the Philadelphia Falcons/Philadelphia Rockets and the Philadelphia Ramblers (EHL), as well as the Philadelphia Warriors and part-time home of the Philadelphia 76ers of the NBA when the Philadelphia Convention Center was unavailable.

Example Input: Question: What team plays at the Minneapolis baseball stadium where McCartney performed? Passage 1:On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.
 Passage 2:Romik Khachatryan began to get involved in football at age 7. Khachatryan began his youth career in SKA-Arai Echmiadzin. The then 16-year-old player played for the club for 11 games and was able to score 2 goals in the 1994 season. The club performed poorly that season, taking 14th place in the Armenian Premier League and was sent to the Armenian First League. Khachatryan joined Kilikia Yerevan. The club, who were soon merged with Pyunik Yerevan, played in season informal and formal, respectively. Following 1996, he joined BKMA Yerevan and stayed at the club for a long time. His first season for the club was initially not good. They had 7 defeats at the start of the Premier League. In the first round, the team finished with one win and 10 losses. Moreover, after the first match of the second round, the club withdrew from the championship and disbanded. Khachatryan himself played only three games and returned to Pyunik. From this period, Khachatryan went to take his career elsewhere. Successful performance for the club provided the opportunity to play in the Armenia national team. At the end of the 1998 Armenian Premier League, he made a transition into Araks Ararat. His skills developed in the new club and he was allowed half of the season to move to the Cypriot First Division. He played for Cypriot clubs Olympiakos Nicosia, APOEL Nicosia and Anorthosis Famagusta. He also returned to Armenia to play for Banants Yerevan, which made it to the finals of the 2008 Armenian Cup. Khachatryan currently plays for Lokomotiv Tashkent.
 Passage 3:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.
