Example Input: Question: How many miles would the Empire Nightingale travel when crossing the Atlantic Ocean to Yorkshire? Passage:Empire Nightingale would appear to have crossed the Atlantic Ocean from the United States independently, as she does not appear as a member of a convoy until 27 June, when she departed Middlesbrough, Yorkshire as a member of Convoy EC 31. The convoy had departed from Southend, Essex the previous day and arrived at the Clyde on 1 July. She left the convoy at Oban, Argyllshire, departing on 3 July for Baltimore, Maryland, United States, which was reached on 22 July. Empire Nightingale departed Baltimore on 10 August for Halifax, Nova Scotia, Canada, arriving five days later. Carrying a cargo of steel, she departed on 21 August with Convoy HX 146, which arrived at Liverpool, Lancashire on 6 September. She left the convoy at Loch Ewe to join Convoy WN 177, which departed from Oban on 5 September and arrived at Methil, Fife on 8 September. Empire Nightingale then joined Convoy FS 589, which departed that day and arrived at Southend on 10 September. She left the convoy at Hull, Yorkshire on 10 September.

Example Input: Question: How long was Robert in the Parliament? Passage:Richard Bennet (d.1619), a Councillor at Law, built Hexworthy House as his seat within the parish. The Bennet family originated in Sussex and settled at Hexworthy during the reign of Queen Elizabeth I (1558-1603). His son was Col. Robert Bennet (1605–1683) of Hexworthy, a Member of Parliament during the Civil War and a noted commander of the Parliamentarian forces. His descendant Richard Bennett-Coffin (d.1796) was the son of Edward Bennett of Lawhitton by his wife Honor Coffin (born 1682), 11th daughter of Richard Coffin (1623-1700) of Portledge in the parish of Alwington in North Devon, lord of the manor of Alwington and Sheriff of Devon in 1683. Richard Bennett-Coffin (d.1796) became heir to the Coffin estates following the death of his childless uncle Richard Coffin (1684-1766). The Coffin family had been established at Alwington since the reign of King Henry II (1154-1189), and remained there in unbroken male succession until 1766. He adopted the name and arms of Coffin, but died without progeny at Esher in Surrey and was buried at Lawhitton where survives his monument. His heir was Rev. John Pine-Coffin (1735-1824), eldest surviving grandson of Dorothy Coffin (1651-1690), eldest daughter of Richard Coffin (1623-1700), who in 1672 married Edward Pyne (1648-1675) of East Down. Her descendants remained seated at East Down manor house until 1866, the Pyne family having occupied it since the 13th century. The last in the Pine-Coffin family to occupy Portledge manor house was Richard Geoffrey Pine-Coffin (1908-1974).

Example Input: Question: In what country did Caracciola work as an apprentice in an automobile factory? Passage:Caracciola began racing while he was working as apprentice at the Fafnir automobile factory in Aachen during the early 1920s, first on motorcycles and then in cars. Racing for Mercedes-Benz, he won his first two Hillclimbing Championships in 1930 and 1931, and moved to Alfa Romeo for 1932, where he won the Hillclimbing Championship for the third time. In 1933, he established the privateer team Scuderia C.C. with his fellow driver Louis Chiron, but a crash in practice for the Monaco Grand Prix left him with multiple fractures of his right thigh, which ruled him out of racing for more than a year. He returned to the newly reformed Mercedes-Benz racing team in 1934, with whom he won three European Championships, in 1935, 1937 and 1938. Like most German racing drivers in the 1930s, Caracciola was a member of the Nazi paramilitary group National Socialist Motor Corps (NSKK), but never a member of the Nazi Party. He returned to racing after the Second World War, but crashed in qualifying for the 1946 Indianapolis 500. A second comeback in 1952 was halted by another crash, in a sports car race in Switzerland.
