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: What age was Pastornicky's replacement in 2012? Passage:Following the conclusion of the 2011 season, Braves general manager Frank Wren highlighted several important areas to improve during the offseason. Since most players were committed contractually to the team in 2012, Wren acknowledged that he would likely make few major changes. One spot that was mentioned for a major overhaul was the shortstop position, where Alex González had played since the Yunel Escobar trade with Toronto in July 2010. González entered the offseason as a free agent and proved too expensive for the team. Wren ultimately allowed prospect Tyler Pastornicky the starting duties in 2012, until he was replaced by Andrelton Simmons in mid-June. When Simmons was hurt in July, Jack Wilson, Paul Janish, and Martín Prado filled in for him. While center fielder Michael Bourn returned to his position in 2012, Wren also suggested that the corner outfield positions were areas of contention. In 2011, the Atlanta outfielders finished the season last in the National League in on-base plus slugging and slugging percentage. Wren stated that right fielder Jason Heyward and left fielder Martín Prado had no guarantee of getting the starting jobs in 2012. On the day after the Braves were eliminated from the playoffs in 2011, Wren said that veteran starter Derek Lowe was unlikely to have a spot in the starting rotation in 2012, due his poor performance in 2011 and a plethora of rookie pitching talent in the Braves farm system. With Lowe guaranteed $15 million in 2012, Wren projected that any of Lowe's salary picked up by another team would significantly assist his efforts to find a shortstop or outfielder. By the end of October, Lowe was traded to the Indians.

Input: Consider Input: Question: What college did Lawson teach at? Passage:The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.
