You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: Was the main residence of the Harcourts, located in Oxfordshire, inhabited by anyone before the Harcourts? Passage 1: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.
 Passage 2:In 1970, 22-year-old Crespo had dropped out of IST and was eventually drafted into military service in the Portuguese Colonial War. He transferred to Mozambique where his military occupation was to check the cement cargoes from Beira to the Cahora Bassa Dam construction site, near Tete. Some time later, due to his good fluency in English, he was placed in the press office of Kaúlza de Arriaga, the commander in chief of the Portuguese Armed Forces in Mozambique, who had coordinated a massive anti-guerrilla operation against FRELIMO separatists in 1970 - the Gordian Knot Operation. While serving in the army, Crespo also entered the newly created School of Medicine of the University of Lourenço Marques where he would complete a number of academic disciplines but did not graduate. He also married Helen de Souza from Johannesburg, a South African woman with Portuguese ancestry who worked in genetics. After the Carnation Revolution left-leaning military coup at Lisbon in April 1974, fresh out of the troop, Crespo fled Mozambique for South Africa.
 Passage 3:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."
