Example Input: Question: How old was Nehru's great uncle when he was born? Passage 1:The Eagles competed in three tournaments during the 201617 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 31 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) 11 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 31 in the opening round (suffering their first season sweep against the Terriers since 199495), and were defeated by Northeastern 24 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:Nehru was born in Allahabad, Uttar Pradesh, India and was son of Brijlal Nehru and Rameshwari Nehru He was educated at the Allahabad University (India), the London School of Economics and at Oxford University. He was awarded the Doctor of Literature degree by the University of Punjab, for his distinguished services in various fields. His grandfather, Pandit Nandlal Nehru, was the elder brother of Pandit Motilal Nehru. He was the cousin to the erstwhile Prime Minister of India, Indira Gandhi (nee Nehru). In 1935, Nehru married Magdolna Friedman (5 December 1908, Budapest, Austria-Hungary - 25 April 2017, Kasauli, Himachal Pradesh, India), a fellow student in the UK who was of an Austrian Jewish background. The ill-treatment of the Jewish community in Europe prompted her father to change her name to Magdolna Forbath. Her nickname was Fori. After marriage, she changed her name to Shobha Nehru. He had four sons named Aditya Nehru, Ashok Nehru and Anil Nehru.
Passage 3: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.

Example Input: Question: How many goals did Stefan Moore score for St Neots Town in the 201112 season? Passage 1:In 60 BC, an internal disturbance occurred among the Xiongnu ruling clique, and Xianxianshan, Prince Rizhu of the Xiongnu stationed in the Turpan Basin, led 12,000 of his troops and 12 royals to pledge allegiance to the Han imperial court. That same year, the Han appointed Zheng Ji as the Protector General of the Western Regions, with his office in Wulei (near Qiuci) to oversee the entire region of the Tarim Basin west to the Pamir. The last Protector General, Dan Qin, was killed during a rebellion led by Yanqi in 13 AD. A brief attempt to restore the protector generalship was launched by Wang Mang in 16 AD, under the new appointed Protector General Li Chong. The armies soon advanced towards the state of Yanqi, but were eventually defeated by Yanqi with its allies. Li Chong fled to the state of Qiuci, and died soon after the fall of Xin Dynasty.
Passage 2:In October 2010, Moore was signed by United Counties League side St Neots Town, for a reported five-figure fee, signing a two-and-a-half-year contract. The club breezed to the top of the table, breaking every record in the United Counties League, including 160 goals in a season and a 130 win at Yaxley. This won them promotion into the Southern League Division One Central for the 201112 season. They also won the Huntingdonshire Senior Cup after beating St Ives Town. They won the Division One Central title to claim a second successive promotion. He joined Leamington in December 2012, and scored three goals in his debut match against Bedworth United on 1 January 2013. Moore signed for Conference North side Brackley Town on 25 March 2012 in a dual registration deal with Leamington. He made his debut two days later in a 11 draw with Halesowen Town. Leamington won the Southern League title in 201213, whilst Brackley qualified for the play-offs with a third-place finish. He left Leamington to play solely for Brackley in January 2014. He scored 12 goals in 19 league games for the "Saints" in the 201314 campaign. Moore returned to Leamington in May 2014 having turned down an extended contract offer from Brackley Town.
Passage 3:However, the most reliable information comes from the memoirs of his personal friend Edward Clodd. Clodd mentioned New York as another claimed location but asserted that Du Chaillu's true birthplace was the French Indian Ocean island territory of Ile Bourbon (now called Reunion). He further claimed that his mother was a mulatto woman. In 1979, historian Henry H. Bucher presented evidence to back Clodd's view, including records of Du Chaillu's father. Bucher argued that Du Chaillu, as a member of the European scientific community, would have tried to obfuscate or conceal the family history that would have labeled him a quadroon. In the 19th century atmosphere of scientific racism, great apes and Sub-Saharan Africans were often linked as sharing a small cranial capacity and an inborn inability to achieve civilization. Du Chaillu's credibility as an African explorer and gorilla expert would have suffered due to his black heritage as a result. Indeed, comments in a letter by Du Chaillu's contemporary, the ethnologist of Africa Mary Kingsley, indicate that at least some scientists who thought poorly of Du Chaillu knew of his ancestry or other discrediting information about him.

He has supervised 17 graduate students and ten postdoctoral fellows.
Passage 2:Francisco "Chico" Serra (born 3 February 1957 in Sao Paulo) is a racing driver from Brazil. He won the 1979 British Formula 3 Championship. He participated in 33 Formula One World Championship Grands Prix for Fittipaldi and Arrows, debuting on 15 March 1981. He made 18 starts, not qualifying for the remaining fifteen races, although he ought to have started as the reserve in the 1982 Swiss Grand Prix. However, Ferrari withdrew Patrick Tambay's entry so late that Serra was not allowed to take part. Serra scored one championship point, for finishing sixth in the 1982 Belgian Grand Prix. After qualifying for the 1982 Canadian Grand Prix, Serra and countryman Raul Boesel had a short scuffle. Serra was furious at Boesel for blocking his last flying lap after waving Keke Rosberg by. Boesel denied that this was intentional. Serra made one CART Champ Car start in 1985 at the Portland International Raceway for Ensign Racing but suffered an engine failure.
Passage 3:On Saturday 2 February 1650 major general Henry Ireton, who was accompanying Oliver Cromwell in his conquest of Ireland, had neither the boats or sufficient weather in order to make a crossing of the river Suir with his army and subsequently headed for the bridge at Ardfinnan to gain another crucial pass over the river Suir, second to the pass at Carrick. In view of taking hold of the strategically placed castle which guarded this crossing from high above, he waited until around four o'clock the next morning to attempt a siege. Defending the castle from the Parliamentarians with a small force of soldiers was David Fitzgibbon (the White Knight), Governor of Ardfinnan Castle for Charles II. With cannons placed on a hill opposite the castle, Ireton bombarded it's once impenetrable walls until there was a large breakthrough after about 8 shots and then proceeded to kill about thirteen of the out-guard and lost only two of his men with about ten wounded. After this the castle was promptly surrendered to the New Model Army who would use it as a garrison throughout their time in Ireland. Fitzgibbon was spared his life for his swift surrender of the castle, but subsequently lost his lands at Ardfinnan and was transplanted to Connacht in 1653. Guns, ammunition and other supplies arriving at Youghal would be brought over the river Blackwater at the pass at Cappoquin and then finally over the river Suir at Ardfinnan to reach the rest of the army in Tipperary. With the end of the Cromwellian campaign of Ireland, the leaving Parliamentarian troops slighted Ardfinnan castle which partially left it in ruins.
