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.
One 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.

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

Now, solve this: Question: Who is the oldest of Joseph's parents? Passage 1:After attending Berkshire Country Day, Aronoff went to music school for one year at the University of Massachusetts Amherst and spent four more years at the Indiana University School of Music (presently known as Jacobs School of Music) as a performance major in classical music as well as spending a summer at the Aspen School of Music run by Juilliard School of Music. He also spent one summer at Tanglewood in the Fellowship program (now Tanglewood Music Center), which at that time was managed by the Boston Symphony Orchestra where he worked with conductors Leonard Bernstein, Aaron Copland and Arthur Fiedler. While studying at Indiana University from 1972 to 1976 Aronoff studied under timpanist George Gaber. He also studied privately with Vic Firth and Arthur Press, both formerly with The Boston Symphony Orchestra. After graduating in 1976 he was offered jobs with the Jerusalem Symphony Orchestra and Quito Ecuador Symphony Orchestra but decided to move to the East Coast to study in Boston with Alan Dawson, a teacher from Berklee College of Music, and with Gary Chester in New York where he began to concentrate on jazz and fusion music.
 Passage 2:He began 2018 in Europe with third at the Czech Indoor Gala and a runner-up finish at the Cinque Mulini. A 5000 m win at the Ethiopian U20 Championships and a personal best of 13:04.63 minutes to win at the Meeting Iberoamericano de Atletismo saw him enter the 2018 IAAF World U20 Championships saw him enter the competition as the second fastest runner after training mate Selemon Barega. He was beaten by the heat, however, and finished fifth in the 5000 m. He made his IAAF Diamond League debut that year, placing seventh at Athletissima. He closed the year with third place at the Great Ethiopian Run. At the start of 2019 he continued to show his strength over distance with second place at the Giro Media Blenio 10K. Turning to the track, he won the Ethiopian national title, was fifth at the Shanghai Golden Grand Prix, then had his first Diamond League victory by winning the 5000 m at the Golden Gala, beating his partner Selemon Barega. He was third at that year's Athletissima and placed fourth at the Diamond League final at the Weltklasse Zürich.
 Passage 3:In the biblical account, Joseph's other son is Manasseh, and Joseph himself is one of the two children of Rachel and Jacob, the other being Benjamin. Biblical scholars regard it as obvious, from their geographic overlap and their treatment in older passages, that originally Ephraim and Manasseh were considered one tribe – that of Joseph. The Book of Revelation, however, accords only Ephraim the tribal name of Joseph. According to several biblical scholars, Benjamin was originally part of the suggested Ephraim-Manasseh single "Joseph" tribe, but the biblical account of Joseph as his father became lost. A number of biblical scholars suspect that the distinction of the Joseph tribes (including Benjamin) is that they were the only Israelites which went to Egypt and returned, while the main Israelite tribes simply emerged as a subculture from the Canaanites and had remained in Canaan throughout. According to this view, the story of Jacob's visit to Laban to obtain a wife originated as a metaphor for this migration, with the property and family which were gained from Laban representing the gains of the Joseph tribes by the time they returned from Egypt; according to textual scholars, the Jahwist version of the Laban narrative only mentions the Joseph tribes, and Rachel, and does not mention the other tribal matriarchs at all.
