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.

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

New input: Question: Which Christian group is older - the oriental Orthodix of Armenia, or the Copts of Egypt? Passage 1:The Lebanese Christians are some of the oldest Christians in the world, preceded only by the oriental Orthodox of Armenia and Copts of Egypt. The Maronite Christians, belong to the West Syriac Rite. Their Liturgical language is the Syriac-Aramaic language. The Melkite Greek Catholics and the Greek Orthodox, tend to focus more on the Greco-Hellenistic heritage of the region from the days of the Byzantine Empire, and the fact that Greek was maintained as a liturgical language until very recently. Some Lebanese even claim partial descent from Crusader knights who ruled Lebanon for a couple of centuries during the Middle Ages, also backed by recent genetic studies which confirmed this among Lebanese people, especially in the north of the country that was under the Crusader County of Tripoli. This identification with non-Arab civilizations also exists in other religious communities, albeit not to the same extent.
 Passage 2:Former Black Sabbath members vocalist Ronnie James Dio and drummer Vinny Appice formed Dio in October 1982 in the United States with bassist Jimmy Bain and guitarist Vivian Campbell. The band released their debut album, Holy Diver in May 1983. Since Ronnie James Dio and Jimmy Bain had played keyboards on the record, they recruited keyboardist Claude Schnell for live shows in 1983 and the following Holy Diver tour. Claude Schnell would later become a full member of Dio, and the band's first recorded effort as a quintet would be 1984's The Last in Line. The band proceeded to release Sacred Heart in 1985 and The Dio E.P. in 1986 before Campbell was fired from the band. The remaining members were joined by guitarist Craig Goldy to release Dream Evil in 1987 before the departure of Bain, Appice and Schnell. They would not play in Dio together again, however Appice would return to the band between 1993 and 1998 as well as Bain between 1999 and 2004.
 Passage 3:The establishment of Decoration Day as an official government holiday (by proclamation, not by law) swiftly occurred, and the holiday was almost immediately a popular one. At Arlington cemetery, the number of people attending the annual event swiftly overwhelmed the limited facilities. The first Decoration Day event was held in front of Arlington House. James A. Garfield, a former Major General in the Union Army (and future President of the United States), addressed a "large crowd" from the mansion's back steps. The following year, President Ulysses S. Grant closed the federal government for the holiday, and most businesses followed, which greatly contributed to attendance at the cemetery. A dais seating 400 people was erected in what remained of "the Grove" at the rear of Arlington House to accommodate speakers and dignitaries—which, for the first time, included President Grant. The Civil War Unknowns Monument, which was located south-southwest of Arlington House, was covered by a canopy. Several American flags hung from the canopy, red-white-and-blue bunting was draped along the monument's top, and numerous floral tributes were laid against it. An estimated 25,000 people attended the event throughout the day. Two sites for ceremonies were used in 1870. A very large speakers' dais was erected near the Sheridan Gate and McClellan Gate on the cemetery's east side, and used for speeches throughout the day. For the more important speakers, a second dais seating 200 was erected at the rear of Arlington House (although not with "the Grove"). A stand, permitting the seating of 500, was built nearby for a grand chorus (which sang for the crowd). Again, the Civil War Unknowns Monument was canopied and decorated. About 20,000 people attended the event that year, with rain keeping the numbers low. In 1871, the speakers' dais moved back to "the Grove" and expanded to accommodate 300 people. Frederick Douglass, the former African American slave and abolitionist, was the featured speaker that year. "Hundreds" of people attended his address, including President Grant. The dais moved again in 1872, this time to a location a few yards to the south of the Civil War Unknowns Monument. The dais was slightly reduced in size so that it only sat 200, but it now included a thrust on which stood a speaker's podium. More than 5,000 people attended the 1872 event.
