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 many sales did What's New make? Passage:In 1983 Linda Ronstadt took a break from recording contemporary music in order to make an album of standards with conductor Nelson Riddle, and their collaboration, What's New went triple Platinum. Barbra Streisand's 1985 release The Broadway Album reached number one and went on to quadruple Platinum certification, so a renewed interest in what came to be known as traditional pop was evident. Mathis had not tried a studio album without current hits or new songs since the ill-fated Broadway project in 1965, so his choice to collaborate with Henry Mancini in 1986 for The Hollywood Musicals, which had a lineup of classics that were mostly from the 1940s, was quite a change of pace. And while he has done some albums of contemporary pop songs since then, the category in which he has received four Grammy nominations since 1992 has been Best Traditional Pop Vocal Album, and the industry has recognized his past work as well. Three of his recordings have been inducted into the Grammy Hall of Fame ("Chances Are" in 1998, "Misty" in 2002, and "It's Not for Me to Say" in 2008), and in 2003 he was given the Grammy Lifetime Achievement Award.
