Example Input: Question: How old was Nehru's great uncle when he was born? 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 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 artists had won the gold medal from the Royal British Society of Sculptors before Montford did? Passage 1:Montford was president of the Victorian Artists Society 1930–32. His generally good work as president was occasionally marred by a certain lack of tact. Some of Montford's best work about this period included the bronzes, "Water Nymph" and "Peter Pan", now in the Queen Victoria Gardens, Melbourne, and "The Court Favourite" in the Flagstaff Gardens, Melbourne. Other work includes relief portraits of eight Australian statesmen in the King's Hall, Parliament House, Canberra, and the war memorial for the Australian Club, Sydney. He was greatly encouraged and pleased on learning in 1934, that his statue of Adam Lindsay Gordon at Melbourne had been awarded the gold medal of the Royal British Society of Sculptors for the best piece of sculpture of the year. Another excellent piece of work is his vigorous statue of John Wesley in front of Wesley Church, Melbourne. His George Higinbotham near the treasury is less successful. Other examples of Montford's work are the memorials to Carlo Catani (St Kilda), William Benjamin Chaffey (Mildura), Sir Ross Macpherson Smith (Adelaide), and 'Pioneer Women' (Sydney). Montford is represented in the National Gallery of Victoria in Melbourne by "Atalanta", the "Spirit of Anzac", and two busts, and he is also represented in the Art Gallery of South Australia in Adelaide. He provided a model from which a portrait bust of Socrates was carved for the University of Western Australia by Victor Wager in 1932.
 Passage 2:After military service in the Imperial Russian Army in World War I, where he reached the rank of a colonel, he joined the 1st Polish Corps of General Józef Dowbor-Muśnicki in western Russia from December 1917 until the Germans forced its dissolution in July 1918. He helped Walerian Czuma organise 1st Kosciuszko regiment at Samara in August 1918 which later formed the 5th Rifle Division in Siberia (sometimes known as the Polish Legion or the Siberian Division) which fought alongside the Czech Legion and the White movement in the Russian Civil War. When the White government of Admiral Aleksandr Kolchak collapsed in December 1919, the Polish Legion joined the general retreat along the Trans-Siberian Railway, until it was surrounded by the Red Army east of Krasnoyarsk in early January 1920. Refusing to surrender, Rumsza led 900 officers and men on an ice march through the taiga slipping through Bolshevik forces until they reached Irkutsk. From there they managed to escape to Harbin in White-controlled Manchuria, and thence to Vladivostok. Rumsza’s force arrived at Gdańsk (Danzig) in Poland in June 1920 and volunteered to fight in the Polish-Soviet War which had just broken out. 
 Passage 3:George W. Bush used "I Won't Back Down" at campaign events during the 2000 presidential campaign but was compelled to stop using the song after receiving a cease and desist letter from Petty's publisher. Petty then went on to perform the song at Al Gore's home after Gore conceded the election to President Bush. Jim Webb used the song for his successful bid for one of Virginia's U.S. Senate seats in 2006, as did Hillary Clinton during the 2008 Democratic presidential primary campaign. The song was also used at campaign events for Congressman Ron Paul of Texas during the 2008 Republican presidential primary campaign, as well as for events for his Campaign for Liberty. The song was also played at an event for Republican Connecticut gubernatorial nominee, Tom Foley. The song was also played at the 2012 Democratic National Convention after speech delivered by President Bill Clinton, in which President Barack Obama came out on stage to salute him.
