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: What age was Albert Aalbers the year Groenewegen arrived in Medan? Passage 1:The Palestinian-dominated Royal Jordanian Army's 17th Armoured Brigade has revolted with Syrian assistance, and has seized the southern part of Jordan, including the port city of Aqaba. However, the major concern for the British Army is that a prototype main battle tank on trials in the Jordanian desert has gone missing. After a terrorist attack in London fails, British military intelligence discovers that the tank is hidden in the ruins of an ancient Crusader fort near Wadi Rum. SAS-trained Major Harry Maxim, who formerly trained the Jordanian Army, is the ideal candidate to send in a commando raid to destroy the tank before it can fall into rebel (and thus Soviet) hands. However, the mission is botched when Maxim's helicopter crashes, and Maxim, an infantryman with no Armoured experience, decides that the best chance for the survival of his small team is to attempt to drive the tank across a hundred miles of rebel held desert to the presumed safety of Saudi Arabia.
 Passage 2:Han Groenewegen worked in the Hague as a freelance architect from 1920 to 1927. Before establishing his own firm, he used to work for the contractor R. Rutgers in the Hague. One of his few works in the Netherlands is the Church of the Holy Heart of Jesus in Schiedam. During the Great Depression, Groenewegen left the Netherlands to established his own new firm in the Dutch East Indies. Many other architects were left for the Indies during the period, e.g. Albert Aalbers. Groenewegen arrived in Medan (on the island of Sumatra) in 1927 to work on the plan for a hospital, the St. Elisabeth's Hospital (1929-1930). He was active in Medan from 1927 to 1942 to work for the Oostkust. Like Schoemaker for the city of Bandung, Gronewegen can be considered as representative of modernist Nieuwe Bouwen in Medan. Among Groenewegen's extensive portfolio in Medan are the expansion of Medan Cathedral (1928), Arnhem Insurance (now Museum Perjuangan TNI, 1930), the Roman Catholic Chinese church in Polonia (1934), Princess Beatrix School (now Immanuel Christian School, 1938), Medan swimming pool (1939), and Oranjeschool (1941). Unlike many of his colleagues however, Groenewegen remained in Indonesia following the independence of the country.
 Passage 3:On 12 March 1550 Edward VI had granted to More's friend, Sir Thomas Cawarden, a large part of the site of the former Blackfriars monastery in London which Cawarden had been leasing since 4 April 1548. Cawarden died in 1559, and More, who was his executor, acquired the property in that year from Lady Cawarden. According to notes made by More (Folger Library MS L.b.425), and other documents, More leased part of the property on 10 June 1560 to Sir Henry Neville and then, at Neville's request, to Richard Farrant, who converted the premises into a playhouse for the Children of the Chapel. Farrant also sublet part of the premises, for which infraction More claimed Farrant had forfeited his lease, but before More could regain possession, Farrant died on 30 November 1580, leaving the lease in his will to his widow, Anne, the daughter of Richard Bower (d.1561), Master of the Choristers of the Chapel Royal. On 20 December 1581, after Farrant's death and after Robert Dudley, 1st Earl of Leicester, had intervened on behalf of William Hunnis, Master of the Children of the Chapel, Farrant's widow, Anne, sublet the premises in the Blackfriars to Hunnis and John Newman. Hunnis and Newman later transferred their interest to a Welsh scrivener, Henry Evans. More than brought suit in June 1583 against Evans, and in Michaelmas term 1583, after first appealing to Sir Francis Walsingham, Anne Farrant brought suit against both Hunnis and Newman. In November 1583 Hunnis petitioned the Queen, and in January 1584 both Hunnis and Newman sued Anne Farrant. In the midst of this legal confusion, as Wallace puts it, 'the Earl of Oxford stepped in', and Evans sold his sublease to Edward de Vere, 17th Earl of Oxford, who retained it for some months before granting it in June 1583 to his servant, John Lyly. Finally, after a delay of a year, the court gave judgment in More's favour in his lawsuit against Evans. More was granted possession of the Blackfriars property in Easter term 1584, and the first Blackfriars Theatre was closed.
