Example Input: Question: Who is the current president of the university that Boston College lost to in the opening round of the 65th Annual Beanpot Tournament? Passage 1:The Eagles competed in three tournaments during the 2016–17 season, the first of which took place during the traditional opening of the college hockey season at the 20th annual Ice Breaker Classic. Played on October 7 and 8 at Magness Arena in Denver, Colorado, the tournament showcased the Eagles playing Air Force in the first round, where they would lose a tight 2-1 match. Boston College faced host Denver in the consolation round, picking up a 3-1 victory for their first win of the season. Air Force would defeat Ohio State in the championship. The Eagles had previously won the ice breaker tournament three times; making their fifth appearance this season. The second tournament of the season took place during the holiday break, where the Eagles made the trip to the PPG Paints Arena in Pittsburgh, Pennsylvania for their second appearance in the Three Rivers Classic in its fifth annual year. The Eagles fell 3–1 to the Quinnipiac Bobcats in the opening round, but picked up the 3rd-place result against Ferris State in the consolation round, winning the (unofficial) shootout of the (official) 1–1 tie. Boston College previously won the title in their first appearance at the tournament in 2012. For their final tournament of the season, the Eagles played in the 65th Annual Beanpot Tournament at the TD Garden in Boston, Massachusetts on February 6 and 13. Boston College lost to rival Boston University 3–1 in the opening round (suffering their first season sweep against the Terriers since 1994–95), and were defeated by Northeastern 2–4 in the consolation game, marking the first 4th place finish for the Eagles since 1993 and the first of Jerry York's tenure.
 Passage 2:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.
 Passage 3:When the American Civil War began, Weitzel was assigned to construct defenses, including in Cincinnati and Washington, as well as for George McClellan in the Army of the Potomac in late 1861. He was then attached to the staff of Major General Benjamin F. Butler as chief engineer of the Department of the Gulf. When Union troops captured New Orleans, Weitzel became assistant military commander and acting mayor. He was promoted to brigadier general in August 1862 and two months later routed a large force of the enemy at Labadieville, Louisiana, which earned him a brevet promotion to major in the Regular Army. Weitzel commanded a brigade in the XIX Corps advancing in Major General Nathaniel P. Banks's operations in western Louisiana during April and May 1863, which led to the siege of Port Hudson. Weitzel was later brevetted lieutenant colonel in the Regular Army, "for gallant and meritorious services at the siege of Port Hudson," which fell on July 9, 1863, days after Vicksburg, Mississippi, about 120 miles upriver, the last Confederate stronghold on the great Mississippi, had fallen. Together those successful sieges and the continuing blockage of Southern ports completed the Anaconda Plan.

Example Input: Question: How old was Adrian "King" Cole the year that headquarters RAAF Station Richmond was formed as a separate entity? Passage 1:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.
 Passage 2:A military flying school was set up at the site of the present-day RAAF base on 28 August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30 June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No. 3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No. 3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (1925–30), Harry Cobby (1930–31), and Bill Bostock (1931–33). Headquarters RAAF Station Richmond was formed as a separate entity on 20 April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No. 22 Squadron flying Hawker Demons, and No. 2 Aircraft Depot, had been established in the preceding months. No. 4 (General Reconnaissance) Squadron was formed in May 1937, followed by No. 6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No. 5 Squadron in April 1936 and No. 9 Squadron in January 1939. No. 23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.
 Passage 3:Campbell began her career as a dietitian at the Baptist College in Brandon, Manitoba. Immigrating to the United States in 1909, she took employment in South Bend, Indiana at the Epworth Hospital as a dietitian and instructor in domestic science and remained until 1911. She returned from Canada in 1914 and entered the Pasadena Hospital Training School for Nurses. In 1917, she graduated having earned her RN designation. The following year, she joined the Nurse Reserves of the United States Army Nurse Corps and began working as a staff nurse at the base hospital of Camp Fremont in Palo Alto, California. After serving at Letterman General Hospital, in San Francisco, she was sent to Fort Leavenworth, Kansas in 1920, to take up a post at the hospital for the United States Disciplinary Barracks. With this move, she became an American citizen and was transferred as a second lieutenant to the Regular Army of the Nurse Corps. Between 1921 and 1922, she was deployed to Coblenz, Germany, serving with the Allied Occupation Forces assisting with Russian famine refugees, influenza victims and war casualties. Returning to the United States, in 1924, she was promoted to first lieutenant after passing the Chief Nursing Examination.

Example Input: Question: Which of the universities Gyorgy worked at has the highest student enrollment? Passage 1:In 1920, after the end of World War I, Gyorgy was offered a job at the University of Heidelberg as an assistant to the physician and researcher Ernst Moro. He remained at the University of Heidelberg until 1933, obtaining full professorship in 1927 at the age of 34 years. It was at the University of Heidelberg that Gyorgy first discovered and isolated riboflavin along with his colleague Th. Wagner-Jauregg and the Nobel-winning chemist Richard Kuhn. Gyorgy remained at the University of Heidelberg until 1933, when the political unrest in Germany spurred his move to the Nutrition Laboratory at the University of Cambridge in England. He stayed as a researcher in there until 1935, during which time he discovered vitamin B.
 Passage 2:Hynde, originally from Akron, Ohio, moved to London in 1973, working at the weekly music paper NME and at Malcolm McLaren and Vivienne Westwood's clothes store. She was involved with early versions of the Clash and the Damned and played in short-lived bands such as Masters of the Backside (1976) and the Moors Murderers (1978 lineup). The Pretenders formed in 1978 after Dave Hill at Anchor Records heard some demos of Hynde's music. He arranged a rehearsal studio in Denmark Street, where a three-piece band consisting of Hynde, Mal Hart on bass (he had played with Hynde and Steve Strange in the Moors Murderers), and Phil Taylor of Motörhead on drums played a selection of Hynde's original songs. Dave Hill was impressed and arranged a day at Studio 51 to record another demo. Although it was rough, he felt he had seen and heard enough "star potential" to suggest that Hynde form a more permanent band to record for his new label, Real Records. Hynde then formed a band composed of Pete Farndon on bass, James Honeyman-Scott on guitar, and Gerry Mcilduff on drums. This band, then without a name, recorded five tracks at Regents Park Studio in July 1978, including "Stop Your Sobbing". Shortly thereafter, Gerry Mcilduff was replaced on drums by Martin Chambers. Hynde named the band "The Pretenders" after the Platters song "The Great Pretender", which was the favourite song of one of her former boyfriends.
 Passage 3:The Paus family (earlier spellings include Pauss and de Paus) () is a Norwegian family that first appeared as members of the elite of 16th-century Oslo. Two brothers from Oslo who both became priests, Hans (1587–1648) and Peder Povelsson Paus (1590–1653), have long been known as the family's earliest certain ancestors. In his book Slekten Paus ("The Paus family"), genealogist S.H. Finne-Grønn traced the family two further generations back, to Hans Olufsson (died 1570), a member of the royal clergy in Norway before and after the Reformation, who served as a canon at the royal chapel in Oslo, St Mary's Church, the seat of government of Norway at the time, and who belonged to the high nobility by virtue of his high ecclesiastical and governmental office. The name Paus is known in Oslo since the 14th century, notably as the name of the Lawspeaker of Oslo Nikolas Paus (mentioned 1329–1347) and as the name of one of medieval Oslo's "city farms" (mentioned 1324–1482) that was probably named after the lawspeaker or his family; while a relation between the older and the younger family of the name in Oslo is plausible, it has not been established. Regardless, the modern Paus family is likely the only surviving family to hail from the medieval city of Oslo which burned down in 1624 without being rebuilt, making it the family with the longest documented history in the Norwegian capital.
