Question: When did the pitcher who Bay hit a grand slam off of in September retire? Passage:Bay got off to a slow start to the 2012 season, finishing spring training with no home runs or RBI, and his regular season, which was derailed further by a broken rib suffered while making a diving catch in the April 23 game against the San Francisco Giants. When Bay returned from the DL on June 8, 2012 against the New York Yankees, he went 0-for-3 with one strikeout. He continued to go 0-for-16 in his return from the DL through June 12, before hitting a single on June 13 against the Tampa Bay Rays. In a home game against the Cincinnati Reds on June 15, Bay left the game in the second inning after crashing into the left field wall and suffering a concussion while attempting to catch a fly ball by Jay Bruce that became an inside-the-park home run. He was subsequently placed on the DL again, and returned again on July 17 against the Washington Nationals. On September 2, Bay hit a grand slam off of Miami Marlins pitcher Mark Buehrle in the first inning of a 52 Mets win. Bay also hit a home run off of Buehrle on September 22 in a 43 Mets win.

Question: Who was the ruler of Prague the year young Alfred was sent there? Passage:Piccaver was born on 5 February 1884 in the Lincolnshire town of Long Sutton to chemist Frederick Herman Piccaver (born 1864, died 17 February 1916) and his wife Sarah Ann Sissons. The Piccavers had been farm laborers, but there were also claims of Spanish ancestry dating back to the Spanish Armada. At a young age, Alfred emigrated with his family to the United States of America. The family resettled in Albany, NY and took American citizenship. Frederick Piccaver worked as head brewer of the Beverwyck Brewery. Alfred joined the choir of Albany's St. Peter's Episcopal Church as a boy soprano. He also became a soloist at the North Reformed Church in Watervliet. The young Piccaver went on to study voice with S. Graham Nobbes, who had been chief instructor of the Emma Willard Conservatory of Music and with Allan Lindsay, conductor of the Troy Conservatory of Music. Alfred later trained to be electrical engineer but he had a talent for singing and in 1905 he enrolled at the Metropolitan School of Opera. The school's director Heinrich Conried recognised his considerable vocal ability and in 1907 sent the young Alfred to Prague, where he studied with Ludmilla Prochazka-Neumann (18721954).

Question: Did Wilt Chamberlain or Jerry West start playing in the NBA first? Passage:The Lakers were founded as the Detroit Gems in 1946 before relocating to Minneapolis, Minnesota and renaming themselves the Lakers (Minnesota's nickname is "The Land of 10,000 Lakes"). The club won several titles led by center George Mikan in the 1950s before moving to Los Angeles in 1960. In 1972 they won another championship led by center Wilt Chamberlain and point guard Jerry West. After acquiring center Kareem Abdul-Jabbar in 1975 and point guard Magic Johnson in 1979, the Lakers built a team that won 5 titles in the 1980s. With the retirement of Johnson and Abdul-Jabbar, they struggled in the 1990s. However, in 1996 the club acquired free agent center Shaquille O'Neal and traded with the Charlotte Hornets for newly drafted shooting guard Kobe Bryant. With the two maturing under coach Phil Jackson, the club turned into a contender in the early 2000s.
