Input: Consider Input: 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.

Input: Consider Input: Question: How large is the lake that the trail passes south of? Passage:Reports from the fur trappers who first entered the mountains and those following mention the trail through the pass as being in long term us by the Shoshone, Bannack, Arapaho, Gros Ventre, Flat Head or Bitterroot Salish, Nez Perce, Crow and others. The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole. To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.

Input: Consider Input: Question: What town did W. J. MacQueen-Pope attend private school in? Passage:MacQueen-Pope, always known by his initials or, familiarly, as "Popie", was the eldest son of Walter George Pope and Frederica MacQueen. He was educated privately and at Tollington School. He first worked in a shipping office but became connected with the theatre as private secretary to George Dance, the playwright, manager and theatrical philanthropist. He tried his hand as a playwright, with limited success: The Times was dismissive of his short play, The Punctual Sex, in 1919. Sir Alfred Butt appointed him business manager at the Queen's Theatre, and after holding similar posts at other West End theatres, and holding the post of manager and secretary of Alexandra Palace from 1922 to 1925, he was appointed general manager of the Duke of York's Theatre in 1927, and was put in charge of the new Whitehall Theatre before it opened in 1930. The Times said of his career, "it was as press representative at the Palladium in 1925 that he began to develop his special talent for passing on to others ... his love and knowledge of the theatre generally and in particular of Drury Lane, of the Haymarket (Theatre of Perfection) and of the Gaiety (Theatre of Enchantment)."
