Example Input: Question: What was the name of the Ottoman governor who presented Robert Rollo Gillespie with an Arabian  horse? Passage 1:He then transferred to India, traveling initially to Hamburg where, though both were in disguise and had no political principles in common, he was warned by Napper Tandy to flee to Danish territory in Altona. He continued overland through Germany, Austria, and Serbia, to the Euxine where he felt obliged to force his ship's captain at gunpoint to take him to Constantinople as agreed, rather than a corsair port for murder or slavery. He passed through Greece without recorded incidents, and took ship for Aleppo. He narrowly saved his own life, and his servant's, in the desert by curing the chief of a band of Arabs, who were planning to murder and rob him. He stayed for some time in Baghdad, where he was presented with a valuable Arabian horse by the Ottoman governor. From Basra he took ship for Bombay, then travelled overland to Madras. He was soon appointed to the command of the 19th Dragoons at Arcot, some 16 miles from Vellore.
 Passage 2:Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.
 Passage 3:As a backbencher in Ralph Klein's Progressive Conservative caucus, Knight moved a number of government bills. The first was 2003's Electric Utilities Act, which made some changes to the government's deregulation of the province's electricity market. Much of the debate around the bill was about whether the government's deregulation had worked well to date. The bill was passed on a party line vote, with Knight's fellow Progressive Conservatives voting unanimously in favour and the opposition Liberals and New Democrats voting unanimously against. Knight also sponsored the Securities Amendment Acts, separate bills with the same name from different years, 2005 and 2006. The first of these was designed to harmonize the securities regulation with that of other provinces. It was supported by Liberals Rick Miller and Bill Bonko, who considered it a step in the right direction. New Democrats gave it a mixed reception, with Ray Martin agreeing that it did make some improvements, but with his colleague David Eggen trying to kill it on third reading, saying that what was needed was a supra-provincial securities regulator. The 2006 edition of the Securities Amendment Act implemented further harmonization, and passed with little debate. The Securities Transfer Act of the same year consolidated and harmonized the province's rules for transferring securities, and passed with all-party support.

Passage 1:The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.
