You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

New input: Question: Of the teams Macon played for, which is the oldest? Passage 1:Engelbach was born in Spain, at Jerez de la Frontera, to English parents. During the 1890s she studied in London at the Westminster School of Art and at the Slade School of Art before completing her studies in Paris. Engelbach had works shown at the Laing Art Gallery in Newcastle and at the Paris Salon. In 1901 she had a picture shown, under her maiden name, at the Royal Academy in London. She was awarded a bronze medal at a Women's International Art Club exhibition held in London. In 1902 she married a C.F.R Engelbach and withdrew from a full-time art and exhibition career to raise a family. Engelbach returned to painting in the late 1920s and had a solo show at the Beaux Arts Gallery in 1931. She went on to resume exhibiting at both the Royal Academy and the Paris Salon and also with the Royal Institute of Oil Painters and the National Society of Painters, Sculptors and Gravers/ Printmakers and became a member of the latter two societies. The Goupil, Tooths and Lefevre galleries were among the commercial concerns that showed her work. Originally Engelbach was a portrait painter but later became a specialist flower painter who also painted landscapes. Her painting Roses, from the 1930s, is held in the Tate collection. A memorial exhibition for Engelbach was held at the Leicester Galleries in 1951.
 Passage 2:Following a vote by the faculty, the pianist Ludovico Bramanti became the new Director of the conservatory in 2014, succeeding another pianist, Maurizio Tarsetti, who had held the post since 2008. In the academic year 2009/2010, the conservatory had an enrollment of approximately 850 students. Of those, 821 were Italian with the remainder from 26 other countries as far afield as Peru, Nepal and Kazakhstan. The conservatory offers bachelor and master diplomas in singing, instrumental performance, composition, musicology, choral conducting, jazz and electronic music. It also trains music teachers for secondary schools and holds regular master classes and seminars. Admission to the diploma courses is based on an entrance examination with five €1000 scholarships awarded annually by the Fondazione Rossini. conservatory has three specialised research laboratories: 20th Century and Contemporary Music; Early Music; and Electronic and Experimental Music (LEMS), which was established in 1971 by the Italian composer Aldo Clementi. There are several permanent ensembles in which both students and faculty participate, including the Symphony Orchestra, Wind Orchestra, Jazz Orchestra, Saxophone Ensemble, and Gregorian Choir. The ensembles and soloists perform a variety of public concerts in Pesaro and the surrounding region during the year, including those celebrating Christmas, Easter, Ferragosto, May Day, Festa della Repubblica, and Saint Cecilia's Day. The conservatory also co-produces Progetto Orfeo, an international university festival of opera and musical theatre, and runs two national music competitions, Harpsichord (established in 1991) and Bassoon (established in 2004).
 Passage 3:Macon was drafted in the second round (twentieth selection) of the 1952 NFL Draft by the Chicago Bears and became the first African-American player on the team; he spent two years as a halfback and return specialist. He was the second African-American to be drafted by the Bears; the first, George Taliaferro, was drafted by them in 1949, but chose to play in the All-America Football Conference. With the Bears, Macon rushed for 324 yards and two touchdowns on 70 attempts while catching 14 passes for 49 yards and two touchdowns. On 22 kick returns, he averaged 30.5 yards per return and 5.9 yards on 24 punt returns. He left the Bears in 1954 to play for the Calgary Stampeders of the Canadian Football League. Bears coach and owner George Halas was not pleased about his departure, blackballing Macon and suing him for $100,000. As a result, the Bears refused to acknowledge Macon being on the team. After being out of football for two years, which he spent as a longshoreman, Macon joined the Hamilton Tiger-Cats in 1957 before leaving in 1959 to resume his longshoreman career, but later joined the Oakland Raiders of the American Football League in 1960. With the Raiders, Macon was converted to defensive back, and was tied for second in the league with nine interceptions, which earned him All-Pro honors.
