Example Input: Question: How old was Stalin the year that the Meskhetian Turks were forced out of Meskheti? Passage 1:The ship's keel was laid down 4 January 1977 by Burrard Dry Dock at their yard in North Vancouver, British Columbia with the yard number 222. The ship was launched on 10 March 1978 and entered in Coast Guard service in March 1979. The ship was named Franklin in honour of Arctic explorer Sir John Franklin. After completing the vessel performed sea trials in the western Arctic and Northwest Passage. While transiting the Northwest Passage, heading to the icebreaker's assigned base in Newfoundland, Franklin lost a propeller in Viscount Melville Sound and was rescued by and returned to the west coast. The two ships then transited to the East Coast of Canada via the Panama Canal. In 1980, the vessel was renamed to Sir John Franklin at the request of the crew. The ship worked out of CCG Base Dartmouth and CCG Base Quebec City for most of the 1980s and 1990s, being tasked to winter icebreaking operations in the Gulf of St. Lawrence and St. Lawrence River and off Newfoundland. During the summer season, Sir John Franklin was often tasked to support the annual Arctic Summer Sealift operation for escorting cargo ships to remote port communities in the Canadian Arctic Archipelago.
 Passage 2:Robinson was born in Manchester to James Arthur Robinson and Ann (née Lamplugh) in 1919. She went to a private school and later the Manchester Girls' High School. After the divorce of her parents in 1938 she went to the University of Hamburg for premedical studies but this was interrupted by the war. Returning to England, she worked at the British Woollen Industries Research Association in Leeds where she attended evening lectures in Paleontology at Leeds University by Dorothy Rayner, which captured her interest. She worked from 1942 to 1945 at the Royal Ordnance factory at Thorp Arch, West Yorkshire. She worked for about two years as a librarian at the Geological Society in London before enrolling for geology at the University College London in 1947. She was influenced at university by J. B. S. Haldane, Walter Georg Kühne and D. M. S. Watson. Graduating in 1951 with first-class honours, he continued post-graduate research and became an assistant lecturer in zoology. She received a Ph.D. in 1957 for her studies on the gliding lizard Kuehneosaurus but she also studied the stratigraphy and fossils of the Mendip Hills in Gloucestershire. She published on the Late Triassic fauna of the Bristol Channel. She was invited through the influence of Haldane to the Indian Statistical Institute at Calcutta by Prasanta Chandra Mahalanobis and helped establish a geology department there. She mentored and influenced Indian researchers and created a program for the study of the paleontology of the Gondwana strata as well as the Maleri Formation in the Deccan region. A symposium on Gondwana Stratigraphy was held in 1967.
 Passage 3:The Meskhetian Turks first arrived in Azerbaijan at the end of the nineteenth century, and more followed in 1918-1920. However, migration to Azerbaijan increased dramatically after World War II when the Soviet Union was preparing to launch a pressure campaign against Turkey. Vyacheslav Molotov, then Minister of Foreign Affairs, demanded to the surrender of three Anatolian provinces (Kars, Ardahan and Artvin); thus, war against Turkey seemed possible, and Joseph Stalin wanted to clear the strategic Turkish population situated in Meskheti, located near the Turkish-Georgian border which were likely to be hostile to Soviet intentions. Thus, in 1944, the Meskhetian Turks were forcefully deported from the Meskheti region in Georgia and accused of smuggling, banditry and espionage in collaboration with their kin across the Turkish border. Nationalistic policies at the time encouraged the slogan: "Georgia for Georgians" and that the Meskhetian Turks should be sent to Turkey "where they belong". Joseph Stalin deported the Meskhetian Turks to Central Asia (especially to Uzbekistan), thousands dying en route in cattle-trucks, and were not permitted by the Georgian government of Zviad Gamsakhurdia to return to their homeland.

Example Input: Question: How many years after the medical center was named after his father did Reed die in the same center? Passage 1:Oldfield, an Australian national, said he was making "a protest against inequalities in British society, government cuts, reductions in civil liberties and a culture of elitism". Oxford number two, William Zeng, denounced Oldfield and described him as "a mockery of a man", while Oxford boat club president Karl Hudspith tweeted "my team went through seven months of hell, this was the culmination of our careers and [Oldfield] took it from us". Educated at the Sydney Church of England Grammar School, the University of Sydney and the London School of Economics, and Fellow of the Royal Society of Arts, Oldfield tweeted the day after the race, "Having been deep within elite institutions I have a very good understanding of them. I protest their injustices – ask anyone that knows me". On his blog, Oldfield compared his actions to those of Emily Davison, the suffragette killed after stepping in front of the King's horse at The Derby in 1913. Despite later stating he had some sympathy for both the rowers and spectators, he said he had no regrets and that he "would have felt less of a man" had he not made the protest. In October 2012, Oldfield was jailed for six months for causing a public nuisance and ordered to pay £750 costs. In June 2013, he was refused leave to remain in the United Kingdom, the Home Office claiming his presence there was not "conducive to the public good". Oldfield, whose wife is from India, appealed on the grounds that she would be threatened in Australia, and in December 2013, the deportation order was overturned. Security for the 2013 race was increased as a result of Oldfield's actions, with Royal Marines, additional stewards and the Metropolitan Police Marine Policing Unit in attendance.
 Passage 2:Irvine Welsh was born in Leith, the port area of the Scottish capital Edinburgh. He states that he was born in 1958, though, according to the Glasgow police, his birth record is dated around 1951. When he was four, his family moved to Muirhouse, in Edinburgh, where they stayed in local housing schemes. His mother worked as a waitress. His father was a dock worker in Leith until bad health forced him to quit, after which he became a carpet salesman; he died when Welsh was 25. Welsh left Ainslie Park High School when he was 16 and then completed a City and Guilds course in electrical engineering. He became an apprentice TV repairman until an electric shock persuaded him to move on to a series of other jobs. He left Edinburgh for the London punk scene in 1978, where he played guitar and sang in The Pubic Lice and Stairway 13, the latter a reference to the Ibrox disaster. A series of arrests for petty crimes and finally a suspended sentence for trashing a North London community centre inspired Welsh to correct his ways. He worked for Hackney London Borough Council in London and studied computing with the support of the Manpower Services Commission.
 Passage 3:Walter Lawrence Reed (4 December 1877 – 1 May 1956) was a major general in the United States Army who served as Inspector General of the Army from 1 December 1935 to 23 December 1939. His father was Army Medical Corps officer Major Walter Reed, namesake of the Walter Reed Army Medical Center. He was born in Fort Apache, Arizona and moved to Washington, D.C. where he spent most of his early life. Reed fought in the Spanish–American War and traveled across the country and to the Panama Canal Zone. He then began working as an inspector during World War I and became the inspector of Base Section Number 5 in February 1919 then worked in the American Expeditionary Forces office. For his work he earned the Distinguished Service Medal. Reed attended various military schools before returning to the Inspector General's department. In 1935 he became the inspector general of the United States Army. He retired in 1940, but was recalled to active duty during World War II, filling a role in the War Department until 1946. Reed died in the Walter Reed Army Medical Center in 1956.
