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.
Example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Problem: Question: How old was Hugh D'Ivry's brother when he held the manor in 1086? Passage 1:The Lakers opened the series with a 115–109 victory at the Boston Garden. In Game 2, the Lakers led 113–111 with 18 seconds left when Gerald Henderson stole a James Worthy pass to score a game tying layup and the Celtics eventually prevailed in overtime 124–121. In Game 3, the Lakers raced to an easy 137–104 victory as Magic Johnson dished out 21 assists. After the game, Larry Bird said his team played like "sissies" in an attempt to light a fire under his teammates. In Game 4, the Lakers had a five-point game lead with less than a minute to play, but made several execution errors as the Celtics tied the game and then came away with a 129–125 victory in overtime. The game was also marked by Celtic forward Kevin McHale's takedown of Laker forward Kurt Rambis on a breakaway layup which triggered the physical aspect of the rivalry. Kareem Abdul-Jabbar would go after Larry Bird later on in the third quarter, and 1981 Finals MVP Cedric Maxwell further antagonized the Lakers by following a missed James Worthy free throw by crossing the lane with his hands around his own neck, symbolizing that Worthy was "choking" under pressure. In Game 5, the Celtics took a 3–2 series lead as Larry Bird scored 34 points. The game was known as the "Heat Game", as it was played under 97 °F-heat, and without any air conditioning at the infamous Boston Garden. In Game 6, the Lakers evened the series with a 119–108 victory. In the game, the Lakers answered the Celtics rough tactics when Worthy shoved Cedric Maxwell into a basket support. After the game, a Laker fan threw a beer at Celtics guard M.L. Carr as he left the floor, causing him to label the series "all-out-war." In Game 7, the Celtics were led by Cedric Maxwell, who had 24 points, eight rebounds, and eight assists as they came away with a 111–102 victory. In the game the Lakers rallied from a 14-point deficit to three points down with one minute remaining, when Maxwell knocked the ball away from Magic Johnson. Dennis Johnson responded by sinking two free throws to seal the Celtics' victory. Larry Bird was named MVP of the series.
 Passage 2:Under Gruden, the Raiders posted consecutive 8–8 seasons in 1998 and 1999, and leapt out of last place in the AFC West. After uniting with journeyman quarterback Rich Gannon, Gruden led the Raiders to the top of the AFC West and they made the playoffs in three consecutive seasons from 2000 to 2002 (the third season was under head coach Bill Callahan). Oakland finished 12–4 in the 2000 season, the team's most successful season in a decade, and its first division title since 1990, ultimately reaching the , where they lost, 16–3, to the eventual Super Bowl champions Baltimore Ravens. In 2001, the Raiders would return to the postseason with a 10–6 record, but in the AFC Divisional Round a negated fumble proved costly as they were defeated, 16–13, in overtime by the eventual Super Bowl champions New England Patriots. While Gruden was with the Raiders, Gruden acquired his nickname "Chucky" from Raiders defensive lineman Grady Jackson, who thought that the coach looked like the fictional character "Chucky" in the 1988 slasher movie Child's Play.
 Passage 3:During the reign of King Edward the Confessor a lady called Elviva (probably a Latin rendering of the Old English name Ælfgifu), held the manor of Ambrosden. The Domesday Book records that by 1086 she had been replaced by Hugh d'Ivry, butler of William the Conqueror and brother of Roger d'Ivry, who owned several manors in Oxfordshire. Hugh's nephew Roger II d'Ivry inherited Ambrosden and by 1194 it was part of the Honour of St. Valery. Ambrosden thus passed to Edmund, 2nd Earl of Cornwall, who in 1288 gave the manor to Ashridge Priory of the Augustinian order of the Brothers of Penitence. Ashridge Priory retained Ambrosden until the priory was dissolved in 1539 in the Dissolution of the Monasteries.
