Question: 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.


Answer: 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


Question: Question: Which political officer now serves as the 2nd in line to become president? Passage:McKellar twice served as President pro tempore of the United States Senate, commencing in 1945, the first to hold the position under the system that has prevailed since of reserving it for the most senior member of the majority party. When Harry Truman became president in April 1945, upon FDR's death, the vice presidency became vacant (the mechanism for filling intra-term vacancies had not yet been created by the 25th Amendment), and so McKellar became the permanent presiding officer of the United States Senate. Also, as the President pro tempore of the Senate had, prior to 1886, been second in the presidential line of succession, behind only the vice president, Truman viewed McKellar as the logical wartime replacement for himself, and asked McKellar to attend all Cabinet meetings. In 1947 Truman successfully lobbied Congress to pass a new Presidential Succession Act restoring both the Speaker of the House and the President pro tempore of the Senate to the succession ahead of the Cabinet secretaries. By the time the law came into effect, McKellar was no longer in the position of President pro tempore, because Republicans held the majority in the 80th Congress. Truman vetoed the Taft-Hartley Act in 1947 to restrict labor unions, which McKellar voted in favor of. As such Truman selected Alben Barkley of Kentucky as his running mate in the 1948 presidential election. When Democrats regained control as a result of the 1948 elections, McKellar again became President pro tempore. He was therefore second in line for the presidency (behind the Speaker of the House) from January 3, 1949 until January 20, 1949, when Alben Barkley took office as Vice President of the United States.


Answer: When Harry Truman became president in April 1945, upon FDR's death, the vice presidency became vacant (the mechanism for filling intra-term vacancies had not yet been created by the 25th Amendment), and so McKellar became the permanent presiding officer of the United States Senate


Question: Question: What man was the lead guitarist for the shortest amount of times? Passage:The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.
