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

Passage:This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481.

Input: Consider Input: Question: How many years had the Cold War been going on at this point? Passage:During the presidential campaign of 1948, as Cold War fears of communist global expansion mounted, critics of the Truman administration heatedly raised the question "Who Lost China?." Criticism mounted after Truman's surprising victory in the election as the Communist Party of China led by Mao Zedong steadily defeated Chinese Nationalist armies of Chiang Kai-shek and was winning the Chinese Civil War.

Melby, who had served for the State Department in the Soviet Union and China during the war, and by Charles Yost. The 1054 page volume was published August 1949, as Mao and his retinue waited outside the city of Beiping, as Beijing was then called, 



Output: During the presidential campaign of 1948, as Cold War fears of communist global expansion mounted, critics of the Truman administration heatedly raised the question "Who Lost China?
