Q: 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.

Q: Question: How many parties took part in the 1988 Knesset elections contested by the NRP? Passage:The Meimad movement was founded on 1 June 1988 by Rabbi Yehuda Amital, and included former National Religious Party Knesset member Yehuda Ben-Meir. It contested the November 1988 Knesset elections, receiving 0.7% of the vote and failing to cross the 1% electoral threshold. Eleven years later, a political arm was established, and joined the One Israel alliance that won the Knesset elections that year. Meimad received one seat, taken by Michael Melchior. It gained a second when Yehuda Gilad replaced Maxim Levy in 2002. Tova Ilan also represented Meimad in the Knesset for a brief spell in 2006, after several other Labour MKs resigned. It attracted moderates among immigrants from the English-speaking world, including Shimon Glick.
