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.

Let me give you an 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.

Question: What other movies did Alan Silvestri compose music for the year Paramount Pictures announced Allied? Passage 1:On 20 October, D-Day for the Leyte landing forces, Mertz escorted landing craft through air attacks to the beach and later in the day patrolled off Dinagat Island at the entrance to Leyte Gulf. Early in the morning of 25 October as the Japanese Southern Force approached Leyte Gulf through the Mindanao Sea, Mertz and patrolled between Desolation Point and Homonhon Island, lest the enemy fleet choose to steam north along the east coast of Dinagat Island to attack the Allied beachhead. When the Japanese entered Surigao Strait, Rear Admiral Jesse B. Oldendorf’s force met and destroyed the enemy armada in the classic “crossing-of-the-T” maneuver known as the Battle of Surigao Strait, part of the overall Battle of Leyte Gulf. Later that same day Mertz splashed a Zero at several hundred yards with heavy machinegun fire.
 Passage 2:On February 6, 2015, Paramount Pictures and New Regency announced that Robert Zemeckis was to direct an untitled World War II romantic thriller, in which Brad Pitt would star. Steven Knight wrote the original script, in development by Graham King's GK Films, which now would be produced by ImageMovers' Zemeckis and Steve Starkey along with King. On June 8, 2015, Marion Cotillard was cast to play a spy along with Pitt, who fall in love during a mission to kill a German official. In August 2015, Knight said that the film would be based on a true story told to him at the age of 21, and also that the shooting would start in January 2016. On January 28, 2016, Jared Harris joined the film. On March 8, 2016, Lizzy Caplan was cast to play Pitt's sister. Executive producers on the film would be Knight, Jack Rapke, Patrick McCormick and Denis O'Sullivan. Alan Silvestri composed the music.
 Passage 3:Donegan was born on 13 July 1961 in Stirling, and educated at St Modan's High School in Stirling and at the University of Glasgow, where his musical career began. He was the bassist in The Bluebells, whose biggest hit was "Young at Heart", and Lloyd Cole and the Commotions. After the latter group split, Donegan became a journalist and an author. Between these roles, he worked as the House of Commons assistant to Brian Wilson MP. Whilst in that role, he was part of a one-off band called the Stop Its that recorded an anti-poll tax song of a similar name. The band also included David Hill, later press spokesman for Tony Blair. and Tim Luckhurst, who later became editor of The Scotsman newspaper, and is Professor of Journalism at the University of Kent. In the late 1980s, Donegan made a number of appearances with South London football team Belair Casuals FC. He is now a golf journalist for The Guardian, having previously worked at The Scotsman. He has held a post with the former publication since 2004, although he has been at the newspaper since 1994, as a general reporter and then as the Scotland correspondent from 1997 to 2004. During the 2010 Winter Olympics, Donegan gained notoriety for his overly critical reviews of the games. Journalists believed that his harsh reviews and similar critiques coming from the British media were made as an attempt to make the games look bad as the following Olympics would be held in London. In 2012, The Guardian made a tongue-in-cheek reference to the severe criticism of the prior Games by inviting a Canadian journalist to similarly critique the Summer Olympics in London as the 'worst ever'.
