Q: Question: What age was Ferdinand I the year Viseu fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

Q: Question: Who is the current governor of the state where Jones was born? Passage:Walter "Wiley" Jones was born in Madison County in northeastern Georgia, on July 14, 1848. His parents were George Jones, a white planter, and Jones' slave, Anne, who had six children by George Jones: Matthew (who superintended the construction of the Wiley Jones Street Car Line), Thomas, Julia (wife of Ben Reed), Wiley, Taylor, and James (who managed many of Wiley's businesses). Wiley received his nickname because of his mischievous nature. At the age of five, he moved to Arkansas with his master and more than forty fellow slaves. They settled on the Governor Byrd plantation. George Jones died in 1858. Anne was called his wife in an 1889 biography of Jones, and she believed that George had promised to free herself and her children upon his death, but no manumission papers were found, and the family was kept as slaves and sold by the estate administer, Peter Finerty, to James Yell, a lawyer and planter in Pine Bluff. Jones worked as a houseboy and carriage driver for his new master. When Jones was ten, he was given to Yell's only son, Fountain Pitts Yell, on the occasion of Pitts Yell's marriage. Pitts was a state representative from 1860 to 1861. During the American Civil War, James Yell became a Major General of the Arkansas State Militia, and Pitts became a colonel in Company S of the 26th Arkansas Infantry Regiment in the Confederate Army. James Yell's was transferred to the Confederate States Army in the summer of 1861, and James left the service and moved to Texas. Jones served for Pitts during the war until Pitts' death in 1864 at the Battle of Pleasant Hill in Louisiana. Jones then joined James Yell and his family in Waco, Texas. There, he served as a porter in a mercantile house for one year. He was then hired to drive a wagon carrying cotton on a route along the Brazos River to San Antonio.


A: Walter "Wiley" Jones was born in Madison County in northeastern Georgia, on July 14, 1848

Q: Question: What is the population of the city which hosted the socialist congress Lunacharsky attended in 1907? Passage:In 1903, the party split into Bolsheviks led by Vladimir Lenin and Mensheviks led by Julius Martov and Lunacharsky sided with the former. In 1907, he attended the International Socialist Congress, held in Stuttgart. When the Bolsheviks in turn split into Lenin's supporters and Alexander Bogdanov's followers in 1908, Lunacharsky supported his brother-in-law Bogdanov in setting up Vpered. Like many contemporary socialists (including Bogdanov), Lunacharsky was influenced by the empirio-criticism philosophy of Ernst Mach and Avenarius. Lenin opposed Machism as a form of subjective idealism and strongly criticised its proponents in his book Materialism and Empirio-criticism (1908). In 1909, Lunacharsky joined Bogdanov and Gorky at the latter's villa on the island of Capri, where they started a school for Russian socialist workers. In 1910, Bogdanov, Lunacharsky, Mikhail Pokrovsky and their supporters moved the school to Bologna, where they continued teaching classes through 1911. In 1913, Lunacharsky moved to Paris, where he started his own Circle of Proletarian Culture.


A:
