Example 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.

Example Input: Question: Which family member did the Governor of Kuban Oblast lose in 1908? Passage:Mikhail Sumarokov-Elston was born on in 1893 to Count Nicholai Felixovich Sumarokov-Elston reserve Lieutenant of the Cavalry Regiment and Countess Sofia Mikhaylovna Koskul. He was the great-great-great-great-grandson of poet Alexander Sumarokov and the Great Great Grandson of Field Marshal Mikhail Kutuzov. He was the nephew of tennis player Count Pavel Sumarokov-Elston, who was his first coach and doubles partner, grandson of Count-General Felix Sumarokov-Elston, Governor of Kuban Oblast, and cousin of the infamous Prince Felix Yussupov, who later became known as one of the collaborators who conspired to kill Grigori Rasputin, cult leader and mentor of Empress consort of Russia Alexandra. Felix provided his own palace for the murder spot and also shot Rasputin once before murdering him with the help of his accomplices. Mikhail had a sister called Elena and a brother Nicholas. At the age of twelve he had a surgery on his right hand, which as a result was rendered unsuitable for tennis and he later switched to left-hand play. First he moved to Dresden and was trained by Kurt Bergmann and George K. Logie. In 1906 he entered the second-class tournament of the Bad Homburg Championships, where he defeated Jack Hillyard amongst many to claim his first title. With this he set a record of being the youngest winner ever at the time in the history of the tournament. In 1908 his father and brother died within two weeks of each other. He moved back to his homeland and graduated first at the Annenschule then at the Law Faculty of the St. Petersburg University.
