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.

Input: Consider Input: Question: How long did the Battle of Jumonville Glen last? Passage:The Ohio Country located between Britain's Thirteen Colonies and France's New France saw France and Britain clash. In 1753 the French sent an expedition south from Montreal that began constructing forts in the upper reaches of the Ohio River. In 1754 the Province of Virginia sent the Virginia Regiment led by George Washington to the area to assist in the construction of a British fort at present-day Pittsburgh, but the larger French force had driven away a smaller British advance party and built Fort Duquesne. Washington and some native allies ambushed a company of French scouts at the Battle of Jumonville Glen in late May 1754. In the skirmish the French envoy Joseph Coulon de Jumonville was left dead leading to a diplomatic incident. The French responded in force from Fort Duquesne, and in July Washington was forced to surrender at the Battle of Fort Necessity. Despite the conflict between them, the two nations were not yet formally at war.

Input: Consider Input: Question: Who founded the record label that signed the group in 1956? Passage:The group was signed to Mercury in 1956, and were also spotted by film producer Sam Katzman. He offered them a part in Rock Around the Clock, the first rock and roll movie, starring Bill Haley. The first single for their new label was shared with Jerry Wallace, who later hit with "How The Time Flies" on Challenge. This record, on the Mercury subsidiary Wing Records was "I Said It And I'm Glad" b/w Jerry Wallace, "Eyes Of Fire Lips Of Wine", which was released February 27, 1956. Their second single was released on the same date. The A-side "Ding Dong", was written by Bell and his friend Pep Lattanzi in 1953. Later known as "Giddy Up a Ding Dong", it was not a hit in the United States, but it was popular in Australia, France, and the UK, where it climbed to number four in the UK Singles Chart. The publicity for the single said, "If these sides don't move you, see a doctor – you're dead." The lyrics to the song are about a horse ride, with a definite western flavor, with the music having a loping, horse like cadence. The group also appeared in the 1956 film, Rumble on the Docks. In 1957, they became one of the first American rock and roll acts to tour the UK in 1956 when they supported Tommy Steele.
