Example Input: Question: What was the enrollment at Norwegian Academy of Music in 1954? Passage 1:Elvestrand was born in Østre Gausdal. His father was an organist at Østre Gausdal Church and Follebu Church, and he allowed Magne to play there in 1927. Elvestrand studied organ under Arild Sandvold and Fartein Valen, who dedicated his opus 33 to him, and studied theory, harmony, and counterpoint under Gustav Fredrik Lange and Per Steenberg. At the age of 18 he was made cathedral organist at Oslo Cathedral while Eyvind Alnæs was ill and then continued in this function after Alnæs's death until Sandvold was appointed to the position. During the commemoration of the 200th anniversary of Bach's death in 1950, Elvestrand played all of Bach's works at Grefsen Church, where he was organist from 1940 to 1967. He debuted as a pianist in 1956, and he performed his first full harpsichord concert in Copenhagen in 1962. Elvestrand served as the organist at Trinity Church in Oslo from 1967 to 1984. As a teacher, he worked at the Oslo Conservatory of Music from 1942 to 1954 and from 1966 to 1973, at the Norwegian Academy of Music from 1973 to 1984, and at the Huseby public school for the blind from 1952 to 1975. He retired in 1981. Elvestrand's solo album was nominated for the 1977 Spelleman Awards in the classical/contemporary music category, but the award was won by Grex Vocalis. Elvestrand died in Germany.
 Passage 2:The band signed to Earache Records in the late 1980s and released their influential debut album, Streetcleaner (1989), to critical acclaim. After the release of Pure (1992) and their major label debut Selfless (1994), they started experimenting with live drums, as well as with hip hop and breakbeat sounds. The resulting albums, Songs of Love and Hate (1996) and Us and Them (1999), were followed by Hymns (2001), which saw a simplification of the band's sound. Shortly after Green's departure in 2002, Broadrick ended Godflesh and pursued various other projects, including Jesu. Broadrick and Green reformed Godflesh in 2010, releasing A World Lit Only by Fire (2014) and Post Self (2017) to critical acclaim.

Example Input: Question: Who wrote the first song that Graham Clark learned to sing? Passage 1:Graham Clarke was born in Holy Name Medical Center in Teaneck, New Jersey on July 11, 1970. Clarke's parents, Lorain Maria Clarke (née Meola), a homemaker, and Thomas Michael "Moose" Clarke, a stockbroker were married in 1960 and had three children before Graham: Thomas in 1961, Dennis in 1962, and Martin in 1965. He spent the first seven years of his life in a split-level home in Dumont, New Jersey. He was frequently in the room when his older brother Tommy would have guitar lessons with musician Bob Berger. Bob noted one time when a screaming Graham had scarlet fever "That boy's screaming on key! That's a C note." Such exposure to music had an obvious influence on him and there is an oft-told family story that claims the first song Graham ever learned to sing was "Me and Julio Down by the Schoolyard," a popular song Tommy was learning on the guitar at the time. At the age of seven, his family moved one town over to Oradell, where he attended St. Joseph Grammar School, and later Bergen Catholic High School. Neither school had a music program so Graham taught himself how to play the guitar using his brother's old fake books.
 Passage 2:Adkin made his debut for Sussex in a List A match against the touring Bangladeshis at the County Ground, Hove, in 2010. Batting at number eight, Adkin contributed 30 runs to Sussex's total of 253 all out, before he was dismissed by Mashrafe Mortaza. He took the wicket of Jahurul Islam in the Bangladeshis innings, with Sussex dismissing them for 104 to win the match by 149 runs. Later in that season he made his first-class debut against Surrey at Woodbridge Road, Guildford, in the County Championship. He scored 45 in the match and took figures of 1–38 with the ball. With the need to concentrate on his university studies, Adkin made just four first-class appearances in the 2011 season, playing in against Oxford MCCU in May, as well as making three appearances in the County Championship later in the season. Adkin also made two List A appearances in that seasons Clydesdale Bank 40, against Derbyshire and the Netherlands.
 Passage 3:The Saint Peter's Square and the Piazza Navona sets were built on the same backlot; after completion of scenes at the former, six weeks were spent converting the set, knocking down the Basilica side and excavating of tarmac to build the fountain. As there had been filming at the real Piazza Navona, the transition between it and the replica had to be seamless. To present the Santa Maria del Popolo undergoing renovation, a police station in Rome opposite the real church was used for the exterior; the scaffolding would hide that it was not the church. Cameron built the interior of Santa Maria del Popolo on the same set as the recreated Santa Maria della Vittoria to save money; the scaffolding also disguised this. The film's version of Santa Maria della Vittoria was larger than the real one, so it would accommodate the cranes used to film the scene. To film the Pantheon's interior, two aediculae and the tomb of Raphael were rebuilt to scale at a height of , while the rest was greenscreen. Because of the building's symmetrical layout, the filmmakers were able to shoot the whole scene over two days and redress the real side to pretend it was another. The second unit took photographs of the Large Hadron Collider and pasted these in scenes set at CERN.

Example Input: Question: How long had the talent agency been operating when they signed He Zhuoyan? Passage 1:The division traced its heritage back to the 7th Guards Tank Corps, formed during World War II in July 1943 from the 15th Tank Corps for its performance in Operation Kutuzov, the Soviet counteroffensive after the Battle of Kursk. It was part of the 3rd Guards Tank Army during the war, and was converted into a tank division like the rest of the tank corps in 1945. Stationed in Czechoslovakia postwar, it was briefly downsized into a regiment in 1946 and relocated to eastern Germany in 1947, becoming part of the Group of Soviet Occupation Forces in Germany, which later became the Group of Soviet Forces in Germany (GSFG). The division was stationed at Roßlau in East Germany for the rest of the Cold War and participated in the Warsaw Pact invasion of Czechoslovakia, Operation Danube, in August 1968. For much of the 1980s it formed part of the 3rd Red Banner Army. As the Cold War wound down, the troops of the GSFG, renamed the Western Group of Forces in 1989, were pulled out of Germany, and the 7th Guards Tank Division was withdrawn to Pyriatyn in Ukraine, where it became a storage base in July 1990.
 Passage 2:Emperor Huizong of Song (7 June 1082 – 4 June 1135), personal name Zhao Ji, was the eighth emperor of the Song dynasty in China. He was also a very well-known calligrapher. Born as the 11th son of Emperor Shenzong, he ascended the throne in 1100 upon the death of his elder brother and predecessor, Emperor Zhezong, because Emperor Zhezong's only son died prematurely. He lived in luxury, sophistication and art in the first half of his life. In 1126, when the Jurchen-led Jin dynasty invaded the Song dynasty during the Jin–Song Wars, Emperor Huizong abdicated and passed on his throne to his eldest son, Zhao Huan who assumed the title Emperor Qinzong while Huizong assumed the honorary title of Taishang Huang (or "Retired Emperor"). The following year, the Song capital, Bianjing, was conquered by Jin forces in an event historically known as the Jingkang Incident. Emperor Huizong, along with Emperor Qinzong and the rest of their family, were taken captive by the Jurchens and brought back to the Jin capital, Huining Prefecture in 1128. The Jurchen ruler, Emperor Taizong of Jin, gave the former Emperor Huizong a title, Duke Hunde (literally "Besotted Duke"), to humiliate him. After his surviving son, Zhao Gou, declared himself as the dynasty's tenth emperor as Emperor Gaozong, the Jurchens used him, Qinzong, and other imperial family members to put pressure on Gaozong and his court to surrender. Emperor Huizong died in Wuguo after spending about nine years in captivity.
