Input: Consider Input: Question: What area of England did the duke of Normandy first land on when invading? Passage:In the 11th century, Errand of Harcourt and his three brothers followed William the Conqueror, duke of Normandy, on the Norman invasion of England, and the brothers were installed with English lands. The English Harcourt branch entered the English peerage, as barons then viscounts then earls. At first the Harcourts had lands in Leicestershire, but in 1191 Robert de Harcourt of Bosworth inherited lands of his father-in-law at Stanton in Oxfordshire, which then became known as Stanton Harcourt. The manor of Stanton Harcourt has remained in the Harcourt family to the present day, although from 1756 to 1948 their main residence was at Nuneham House, also in Oxfordshire. Simon Harcourt was created Baron Harcourt in 1711 and Viscount Harcourt in 1721. The third viscount was created Earl Harcourt in 1749, but all titles were extinguished with the death of marshal William Harcourt, 3rd Earl Harcourt, in 1830. His cousin Edward Vernon, Archbishop of York, thus inherited the majority of that branch's lands and titles and took the name and heraldic shield of the English Harcourt family by royal authorisation on 15 January 1831. This created the Vernon-Harcourt branch, descended from a Harcourt woman. The title Viscount Harcourt was created a second time in 1917 for Lewis Harcourt, but the title was again extinguished on the death of his son.

Output: In the 11th century, Errand of Harcourt and his three brothers followed William the Conqueror, duke of Normandy, on the Norman invasion of England, and the brothers were installed with English lands

Input: Consider Input: Question: Which team won more games the year Cowan started with the Rams, the Vikings or the Cowboys? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

Output: Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975
