Input: Consider Input: Question: Was the record company that signed Rising Sons founded before 1900? Passage:In 1964 he moved to Santa Monica, California, and formed Rising Sons with fellow blues rock musician Ry Cooder and Jessie Lee Kincaid, landing a record deal with Columbia Records soon after. The group was one of the first interracial bands of the period, which likely made them commercially unviable. An album was never released (though a single was) and the band soon broke up, though Legacy Records did release The Rising Sons Featuring Taj Mahal and Ry Cooder in 1992 with material from that period. During this time Mahal was working with others, musicians like Howlin' Wolf, Buddy Guy, Lightnin' Hopkins, and Muddy Waters. Mahal stayed with Columbia after the Rising Sons to begin his solo career, releasing the self-titled Taj Mahal in 1968, The Natch'l Blues in 1969, and Giant Step/De Old Folks at Home with Kiowa session musician Jesse Ed Davis from Oklahoma, who played guitar and piano (also in 1969). During this time he and Cooder worked with the Rolling Stones, with whom he has performed at various times throughout his career. In 1968, he performed in the film The Rolling Stones Rock and Roll Circus. He recorded a total of twelve albums for Columbia from the late 1960s into the 1970s. His work of the 1970s was especially important, in that his releases began incorporating West Indian and Caribbean music, jazz and reggae into the mix. In 1972, he acted in and wrote the film score for the movie Sounder, which starred Cicely Tyson. He reprised his role and returned as composer in the sequel, Part 2, Sounder.

Input: Consider Input: 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.

Input: Consider Input: Question: How old was John of Damascus when the Islamic Caliphate overtook the land of his home? Passage:The earliest surviving written criticisms of Islam are to be found in the writings of Christians who came under the early dominion of the Islamic Caliphate. One such Christian was John of Damascus (c. 676–749 AD), who was familiar with Islam and Arabic. The second chapter of his book, The Fount of Wisdom, titled "Concerning Heresies", presents a series of discussions between Christians and Muslims. John claimed an Arian monk (whom he did not know was Bahira) influenced Muhammad and viewed the Islamic doctrines as nothing more than a hodgepodge culled from the Bible. Writing on Islam's claim of Abrahamic ancestry, John explained that the Arabs were called "Saracens" (Greek Σαρακενοί, Sarakenoi) because they were "empty" (κενός, kenos, in Greek) "of Sarah". They were called "Hagarenes" because they were "the descendants of the slave-girl Hagar".
