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.

 Passage 2:Badree first played for an overseas Twenty20 franchise in January 2013, when he played for the Khulna Royal Bengals in the 2013 Bangladesh Premier League (BPL) season. Later in the year, he signed with the Rajasthan Royals for the 2013 Indian Premier League (IPL), although he played only a single game (against the Delhi Daredevils). In the 2014 IPL auction, Badree was bought by the Chennai Super Kings for US$50,000. He went on to play four matches for the team during the 2014 season, but took only two wickets, with Ravichandran Ashwin and Ravi Jadeja being the preferred spin options. Later in 2014, Badree signed with the Brisbane Heat for the 2014–15 Big Bash League season in Australia. He was unable to play any matches due to a shoulder injury, but re-signed for the 2015–16 season. He struggled for form early in the season, going wicketless in his first three games, but eventually bounced back to finish as his team's leading wicket-taker, with nine wickets from eight matches. This included 5/22 in the final game of the season, against the Melbourne Stars.
 Passage 3:In the 1960s, proportionalism was a consequentialist attempt to develop natural law, a principally Roman Catholic teleological theory most strongly associated with the 13th-century scholastic theologian Thomas Aquinas, but also found in Church Fathers such as Maximus the Confessor and John of Damascus, as well as early pagan schools of philosophy such as Stoicism. The moral guidelines set down by Roman Catholic magisterial teachings of Natural Moral Law are mostly upheld in that intrinsically evil acts are still classified so. In certain situations where there is a balance of ontic goods and ontic evils (ontic evils are those that are not immoral but merely cause pain or suffering, ontic goods are those that alleviate pain or suffering). Proportionalism asserts that one can determine the right course of action by weighing up the good and the necessary evil caused by the action. As a result, proportionalism aims to choose the lesser of evils. Pope John Paul II rules out the 1960s proportionalism in his encyclicals Veritatis Splendor, promulgated in 1993 (cf. section 75), and in Evangelium Vitae, 1995 (cf. article 68). Instead he offers an account of moral action based on the object of the act (finis operis), the intention of the person performing the act (finis operantis), and the circumstances surrounding the action.
