Example Input: Question: Is Vitebsk the capital of a country? Passage:A.P. Rosengolts was born in Vitebsk on November 4, 1889. He was the son of a Jewish merchant. He joined the Bolshevik faction of the Russian Social-Democratic Workers' Party (RSDRP) in 1905, the year of the first, abortive Russian Revolution. He worked as an insurance agent and carried out work for the Bolshevik party in Vitebsk, Kiev, Ekaterinoslav and Moscow. Rosengolts played an active role in the Revolution of 1917. He was a member of the Executive Committee of the Moscow City Council, the Moscow Military-Revolutionary Committee and the All-Russian Military-Revolutionary Committee. He was a leading officer in the Red Army and, during the Russian Civil War, worked closely with L.D. Trotsky. After the Civil War, Rosengolts worked successively for the Commissariats of Transportation and Finance and the Directorate of the Red Army Air Force. He served as ambassador to Britain from 1925 to 1927 and oversaw Soviet espionage in Britain. He became a member of the Central Committee of the Communist Party of the Soviet Union in 1927 and held various high positions in the Communist Party and the Soviet government. In 1930 he was appointed People's Commissar of Foreign Trade. On June 14, 1937, Rosengolts was dismissed from this office and on October 7, 1937, he was arrested. He was one of the defendants of the third Moscow Trial, along with Nikolai Bukharin, Alexey Rykov and other prominent Soviet officials. The accused faced a long list of capital charges, including plotting to assassinate Lenin and Stalin, espionage and sabotage. Like most of his co-defendants, Rosengolts confessed. He was convicted, sentenced to death and shot on March 15, 1938 in Moscow. He was rehabilitated in 1988.

Example Input: Question: Which major French city near Aurillac has a larger population? Passage:Aurillac is at above sea level and located at the foot of the Cantal mountains in a small Sedimentary basin. The city is built on the banks of the Jordanne, a tributary of the Cère. It is south of Paris and north of Toulouse. Aurillac was part of a former Auvergne province called Haute-Auvergne and is only away from the heart of the Auvergne Volcano Park. Access to the commune is by numerous roads including the D922 from Naucelles in the north, the D17 from Saint-Simon in the north-east, Route nationale N122 from Polminhac in the east which continues to Sansac-de-Marmiesse in the south-west, the D920 to Arpajon-sur-Cère in the south-east, and the D18 to Ytrac in the west. The Figeac-Arvant railway passes through the commune with a station in the centre of town but there is no TGV service. About 50% of the commune is urbanised with farmland to the east and west of the urban area.

Example Input: Question: How many times did the Hotspur when the FA Cup? Passage:McIlroy was born in Lambeg, County Antrim and he was introduced to football at an early age as his father, Harry played for Lisburn Distillery and his uncle, Willie played for Portadown. After leaving school McIlroy played for Glentoran before joining Burnley in March 1950 for £7,000. He soon cemented his reputation as one of the finest scheming inside forwards since World War II. He was dubbed as the 'Brain' of Burnley and was a very composed passer of the ball only releasing it when he was sure of finding a teammate. His neat footwork made him a crowd favourite at Turf Moor and indeed for the Northern Ireland national team where he made 55 caps. He helped Burnley win the First Division in 1959–60 and reach the FA Cup Final in 1962, losing 3–1 to Tottenham Hotspur. After 497 matches for the "Clarets" scoring 131 goals, McIlory was allowed to leave for Stoke City for a cut price £25,000, which came as a shock to the Burnley fans who branded chairman Bob Lord 'insane'.
