PROBLEM: Question: How many years apart in age were Sweyn's sons? Passage:Gorm's son, Harald Bluetooth succeeded his father as king and married possibly three times with Gunhild, Tove and Gyrid. Harald had a son named Sweyn Forkbeard. Sweyn succeeded his father as king and married Gunhild (Świętosława of Poland). They had a son named Cnut the Great. Sweyn also ruled England in his lifetime and established the Danish Empire. When Sweyn died, his elder son Harald Svendsen became the King of Denmark, while England's former king, Ethelred, reclaimed the throne. Following Harald's death, his brother Cnut the Great became king, re-established the Danish North Sea Empire. He married Emma of Normandy with whom he had a son named Harthacnut. When Cnut died (and after the brothers of Harthacnut also had died), Harthacnut became king of Denmark and England. Upon his death, Edward the Confessor became ruler of England in 1042. Sweyn Forkbeard also had a daughter, Estrid, from whom all ruling kings and queens of Denmark after 1047 descend.

PROBLEM: Question: Are both of the band members who put out the album "Flags" still alive? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

PROBLEM: Question: How much was Alford purchased for? Passage:Timothy Woodbridge (February 27, 1709 – May 10, 1774) was an American missionary, deacon and schoolteacher, later a judge, representative, and Superintendent of Indian Affairs, from Springfield, Massachusetts, who spent most of his adult life in Stockbridge, Massachusetts, teaching the Mahicans and other Native Americans to read and write, English customs and the Christian religion. About him, Jonathan Edwards said, "By his long-proved justice and integrity, he has gained a vast esteem with the Indians". Reverend John Sergeant described his efforts in this way: "Mr. Woodbridge ... has a very numerous school and a tedious task of it; lives a very lonesome life; is indeed indefatigable in his business; and no body deserves more of the publick than he." Gideon Hawley called him "a man of abilities... always poor, and had a powerful party against him; but he rose to be the first man in the county." Timothy worked very closely with all three men. He was instrumental in the purchase of large tracts of land in western New England from the Native Americans, such as modern-day Lenox and Alford, Massachusetts, by parlaying this reputation and experience.
