Question: Which of Harald's wives was the mother of his son Sweyn? 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 (Swietosawa 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.

question:
Question: How large is the area of the field were Will and the person he shared it with in 2009? Passage:Although in 2008 Baseball America projected Venable as an every day starter for the Padres in 2010, some experts questioned whether he would be a long-term solution in center field for the team. Venable started the 2009 season with the Padres' Triple-A affiliate, Portland Beavers, but he was recalled by the Padres on June 3. His father, Max, served as the Beavers' hitting coach in 2009. Following the July 5 trade of Scott Hairston to the Oakland Athletics, Venable shared right field with Kyle Blanks. On July 12 against the San Francisco Giants, he had his first home run of the season in his first career four-hit game. Between July 30 and August 5, he homered in five of seven games. In an August 23 game against the St. Louis Cardinals, he was involved in a bench-clearing incident when Albert Pujols thought he threw an elbow while being tagged out. In 2009, he posted 12 home runs and tallied 38 runs batted in (RBI), while defensively 493.2 of his 643 innings were spent in right field and only 117 in center field.

question:
Question: Which school Hodes started teaching at after WWII has a higher enrollment? Passage:Hodes worked as an intern and resident at the Children's Hospital of Philadelphia until 1935, when he moved to Baltimore to take up a position at the Harriet Lane Home of Johns Hopkins Hospital as the dispensary director. In 1936, he developed a method that used ultraviolet light to reduce the infectiousness of viruses, a technique that later was used to create commercial vaccines against rabies and influenza. He became a pediatrician at Johns Hopkins in 1938 while also serving as the medical director of Sydenham Hospital for Communicable Diseases. During an outbreak of diarrhea in 1942, he isolated the first virus known to cause diarrhea, later identified as rotavirus. The same year, he became the first to isolate the measles virus from the brain of a child who had died from measles encephalitis. While stationed in Guam with the U.S. Navy in World War II, he discovered that the Japanese encephalitis virus was spread by mosquitoes. Hodes continued working in Baltimore after World War II, and started teaching at the Johns Hopkins School of Medicine and School of Hygiene, as well as the University of Maryland School of Medicine.
