Example Input: Question: Did Stren study at multiple institutions within the same country between 1862 and 1865? Passage:Stren studied at Lillehammer Latin- og Realskole, at Qvams skole in Christiania and at the Swiss Federal Institute of Technology Zurich from 1862 to 1865. In 1866 he started working as a draftsman for Kanalvsenet, the body for exploitation of Norwegian water resources, and held various positions at Kanalvsenet over a period of 41 years. He ended his career as manager for the Bandak-Norsj Canal from 1891 to 1907. The boat locks of the Bandak-Norsj Canal could lift boats with a length of up to 100 feet. The canal became an important water transport system, and also a tourist destination. Stren was a counsellor for industrialist Sam Eyde, the founder and first mangager of Norsk Hydro, who acquired rights for exploiting waterfalls for hydroelectric power. Stren published maps and overviews of water resources in Norway, such as his map from 1904. He was the first editor of the magazine Norsk Teknisk Tidsskrift, which he edited from 1883 to 1886. He was also a proponent for the construction of the Holmenkoll Line, and chaired the board of directors for ten years from 1896. He was decorated Knight of the Royal Norwegian Order of St. Olav in 1893.

Example Input: Question: Does the town where Abernethy was was born have a larger current population than the nearby port town his family moved to when he was a child? Passage:Thomas Abernethy was born in 1803 at Longside in northeast Scotland. While he was a child, his family moved to Peterhead, a nearby port. His parents were James Abernethy, a stonemason, and Isabella Robertson. Thomas had an elder sister, Ann, who was born in 1801, and twin brothers, James and William, who were both born in 1816. Thomas went to sea at the age of ten and when he was about twelve he was apprenticed as a merchant seaman on the sloop Friends. He travelled to the West Indies and twice to Newfoundland. In 1819, he became a greenhand on the maiden voyage of the Peterhead whaling ship Hannibal, which hunted bowhead whales around the eastern coast of Greenland, and in its third season sailed into the Davis Strait on the western coast, where ice conditions can be much heavier. In 1829, Abernethy married Barbara Fiddes, the daughter of a ship's carpenter, and they lived at Deptford, southeast London, near the Royal Naval docks. They had no children.

Example Input: Question: Where did the person who convinced Rita to return to the United States grow up? Passage:While in New York, Fornia studied with Emil Fischer and Sofia Scalchi in New York City and then, under Fischer's advice, moved to Berlin in 1899 to study under Selma Nicklass-Kempner. Kempner, later the teacher of Frieda Hempel, trained her as a coloratura soprano. She made her professional debut with the Hamburg State Opera in 1901 as Eudoxie in Halevy's La Juive. Over the next two years she sang mostly coloratura soprano roles in Germany and France, largely with the Hamburg State Opera who offered her a contract. Her other roles in Hamburg included Rosina in The Barber of Seville and the Queen of the Night in The Magic Flute. From the Fall of 1902 through the summer of 1903 she studied with Jean de Reszke in Paris. Reszke was convinced the Fornia was actually a mezzo-soprano and trained her voice accordingly. Under Reszke's recommendation to Henry Savage, Fornia returned to America in August 1903 to join the Savage English Grand Opera Company where she sang both mezzo-soprano and soprano roles until 1906. Her first performance with the company was as Siebel in Charles Gounod's Faust at the Brooklyn Academy of Music on 21 September 1903. Her other roles with Savage's company included Musetta in Giacomo Puccini's La boheme, Nedda in Pagliacci, Santuzza in Cavalleria rusticana, both Brunnhilde and Sieglinde in The Valkyrie, both Elisabeth and Venus in Wagner's Tannhauser, and both Leonora and Azucena in Verdi's Il trovatore.
