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.

Question: How old was William Havemeyer's son when he retired from the sugar refining business? Passage:William Havemeyer (1770-1851) left Germany at age 15 and arrived in New York City after learning the trade of sugar refining in London. In New York he managed a sugar house on Pine Street before opening his own refinery on Vandam Street with his brother, Frederick Christian Havemeyer, who had come to New York in 1802. Together the two brothers operated the W. & F.C. Havemeyer Company sugar refineries, before passing the business on to their sons. His son William Frederick Havemeyer, retired from the sugar refining business in 1842 and entered politics, eventually serving three terms as Mayor of New York. In 1855 the family relocated their refineries to Brooklyn, where they remained as the business grew to acquire a commanding share of the United States sugar refining market under the leadership of Frederick's grandson, Henry Osborne Havemeyer. The Havemeyer refineries were incorporated as the American Sugar Refining Company in 1891 and became known as Domino Sugar in 1900. In the 20th century several of the family's members made notable contributions to the arts. Henry Osborne Havemeyer and his wife Louisine Havemeyer made large bequests to the Metropolitan Museum of Art and their daughter Electra Havemeyer Webb founded the Shelburne Museum.
