Given the task definition, example input & output, solve the new input case.
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.

The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input case for you: Question: Between Duke Albert and the man he wanted to liberate, which one is older? Passage 1:After the war, Norden wrote material for comedian Dick Bentley, before meeting Frank Muir (who wrote for comic actor Jimmy Edwards) in 1947; they were brought together by producer Ted Kavanagh. Muir and Norden's first joint venture was a radio show for both performers, Take it from Here!, which they scripted from 1948 to 1959. They went on to write many successful radio and television scripts, including Whack-O! (1956–1960) and three series of Faces of Jim (1961–1963) which were vehicles for Jimmy Edwards. They also wrote the satirical sketch Balham, Gateway to the South for the BBC Third Programme. The sketch, which had originally been broadcast in 1948 as part of a comedy series called The Third Division and which featured actor Robert Beatty, was later performed by Peter Sellers for his LP, The Best of Sellers (1959). In the early 1960s, Muir and Norden wrote the sitcom Brothers in Law, an early series featuring Richard Briers, and its spin-off Mr Justice Duncannon.
 Passage 2:Andrew Geoffrey Lyne FRS (born 13 July 1942) is a British physicist. Lyne is Langworthy Professor of Physics in the School of Physics and Astronomy, University of Manchester, as well as an ex-director of the Jodrell Bank Observatory. Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group. Lyne was educated at The Portsmouth Grammar School, the Royal Naval School, Tal Handaq, Malta and at St. John's College at the University of Cambridge (natural sciences), continuing to the University of Manchester for a PhD in Radio Astronomy. Lyne writes that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."
 Passage 3:In 1488 Duke Albert III "the bold" of Saxony, the Margrave of Meissen, campaigned to against the rebellious Flanders, aiming to liberate Emperor Maximilian I, who was held prisoner by the citizens of Bruges. As a reward, Maximilian I appointed Albert III governor of the Netherlands and, as compensation for the cost incurred, Albert was appointed in 1498 as hereditary governor of Frisia, with an understanding that he'd have to subdue Frisia by force of arms before he could take up this post. After subduing the Frisians, Albert III rushed to Leipzig to attend the Diet, the Frisians revolted and laid siege to Franeker, where Albert's second son, Henry had taken up the post of governor. Albert rushed back to Frisia and freed Henry. He then conquered Groningen before dying in Emden on 12 September 1500. Henry inherited the post of governor of Frisia. However, the Frisians kept resisting his rule and he resigned on 30 May 1505 in favour of his brother George, in exchange for two districts in the Ore Mountains.
