Question: After the party split into two in 1903, which leader of the resulting parties was born the earliest? 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.

Question: How old was Peder Paus during the Reformation? Passage:The Paus family (earlier spellings include Pauss and de Paus) () is a Norwegian family that first appeared as members of the elite of 16th-century Oslo. Two brothers from Oslo who both became priests, Hans (1587–1648) and Peder Povelsson Paus (1590–1653), have long been known as the family's earliest certain ancestors. In his book Slekten Paus ("The Paus family"), genealogist S.H. Finne-Grønn traced the family two further generations back, to Hans Olufsson (died 1570), a member of the royal clergy in Norway before and after the Reformation, who served as a canon at the royal chapel in Oslo, St Mary's Church, the seat of government of Norway at the time, and who belonged to the high nobility by virtue of his high ecclesiastical and governmental office. The name Paus is known in Oslo since the 14th century, notably as the name of the Lawspeaker of Oslo Nikolas Paus (mentioned 1329–1347) and as the name of one of medieval Oslo's "city farms" (mentioned 1324–1482) that was probably named after the lawspeaker or his family; while a relation between the older and the younger family of the name in Oslo is plausible, it has not been established. Regardless, the modern Paus family is likely the only surviving family to hail from the medieval city of Oslo which burned down in 1624 without being rebuilt, making it the family with the longest documented history in the Norwegian capital.

Question: What religion did the slavic tribes follow prior to converting to Christianity? Passage:Slavic tribes settled in the Balkan region including North Macedonia by the late 6th century AD. During the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c. 680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, centred on the city of Bitola, forming a second route for the Bulgar definitive settlement on the Balkan Peninsula at the end of the 7th century. Presian's reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia. The Slavic tribes that settled in the region of Macedonia converted to Christianity around the 9th century during the reign of Tsar Boris I of Bulgaria. The Ohrid Literary School became one of the two major cultural centres of the First Bulgarian Empire, along with the Preslav Literary School. Established in Ohrid in 886 by Saint Clement of Ohrid on the order of Boris I, the Ohrid Literary School was involved in the spreading of the Cyrillic.
