[EX Q]: 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).

[EX Q]: 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.

[EX Q]: Question: Was Leland Stanford older than Abraham Lincoln the year Davis set sail for San Francisco? Passage:Davis sailed for San Francisco, California, around Cape Horn in 1852, and upon arriving, engaged for a brief time as a gold miner, a lumber supercargo surveyor for a coastal steamer, and a purser for the Pacific Mail Steamship Company. In addition he helped found the Mercantile Library Association of California (its oldest public library). Under his administrative tutelage interest in the library was restored with his creation of a library catalog (an act which later lead to his poor eyesight). He resigned in 1855 and relocated to San Francisco in 1860 at which time he established the highly successful Golden Gate Flouring Mills and the Sperry Flour Company. He was elected a member of the American Antiquarian Society in 1862. When the American Civil War broke out, he served in the secretive San Francisco-based Home Guard acting to secure both the loyalty of California to then Union President Abraham Lincoln and the election of Leland Stanford as governor of California (by patrolling the polls on election day). He presided over the Produce Exchange of San Francisco from 1867 to 1877 until he was elected as a Republican to the United States House of Representatives of the Forty-fifth and Forty-sixth Congresses (March 4, 1877 - March 3, 1881), where on June 8, 1878 he spoke in support of a bill to restrict Chinese immigration. He was an unsuccessful candidate for reelection in 1880 to the Forty-seventh Congress.
