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: How much older was Jacques Offenbach compared to Henri when Henri performed at the Strand Theatre with Florence St. John's Opera company? Passage 1:Born in 1941, Belanger attended public schools in Bristol, Connecticut. He has degrees from Haverford College (A.B., 1963) and from Columbia University (M.A., 1964; Ph.D., 1970), where he studied under James L. Clifford, Allen T. Hazen, and John H. Middendorf. Between 1966 and 1971, while working on his dissertation on aspects of the 18th-century London book trade, he taught advanced prose composition courses at the Columbia University School of General Studies, an activity leading to the 1972 publication of The Art of Persuasion, a writing manual co-authored with J. Steward LaCasce. While in England on a Columbia traveling fellowship in 1968–69, he revised the book production sections of the 18th-century volume of the New Cambridge Bibliography of English Literature (NCBEL), working with Graham Pollard, who had compiled the original sections for the first edition of CBEL, published in 1940. With Jane Marla Robbins, he co-authored and co-directed a one-character play starring Robbins called Dear Nobody, based on the life of the 18th-century diarist and novelist, Fanny Burney. The play ran Off-Off-Broadway in 1968; it later had a five-months' Off-Broadway run at the Cherry Lane Theatre in 1974.
 Passage 2:Cyril Williams played locally in Bristol. Bob Hewison signed Williams in May 1939 for Bristol City without making the first team in the three league matches in the truncated 1939–40 season. Williams played as a guest for Reading and Tottenham Hotspur during the Second World War. During the 1939–1945 war time Williams also made 53 appearances scoring 21 goals in regional league matches, 13 appearances scoring 6 goals in other leagues and 28 appearances scoring 11 goals in war time cup competitions for Bristol City. Cyril Williams continued his career for Bristol City after the war. Cyril Williams finally made his League debut at inside left in a 3–4 defeat at Aldershot on 31 August 1946 at the age of 24 years. When Bristol City finished 3rd in the Division Three South Williams made 41 appearances, missing only one match, scoring 17 goals including a hat-trick in the 3–1 win at Mansfield Town on 17 May 1947. Williams was part of a goalscoring forward trio of Bill Thomas 14 goals and Don Clark a record 36 goals as Bristol City were highest scorers in the Division with 94 goals. The following season inside right Len Townsend joined from Brentford F.C. scoring 31 goals, Clark netted 22 goals and Willams 10 goals from 37 appearances. This trio scored 63 of the 77 League goals in 1947–48. Williams also scored an FA Cup hat-trick in a 9–2 win v Dartford in a 1st round replay on 6 December 1947. Townsend & Clark also scored hat-tricks v Dartford in the same game. In June 1948 Cyril Williams moved to West Bromwich Albion in exchange for Cliff Edwards plus £500. There was thunderous wrath among "Robins" fans at the sale of their ball playing schemer with the silky skills who had been the creative force behind the ascent up the Third Division South table since the war. West Bromwich Albion finished as runners up in the Second Division in 1948–49 with Williams making 31 appearances scoring 9 goals including another hat-trick in a 5–2 win v Grimsby Town on 11 December 1948. Williams also played in all 4 FA Cup ties as West Brom reached the 6th round losing 0–1 at Wolverhampton Wanderers. Playing in the First Division in 1949–50 Williams made 26 appearances scoring 8 goals. After 14 appearances scoring two goals in 1950–51 for West Brom Cyril Williams moved back to Bristol City in August 1951 for £4,500. Williams scored on his return in a 3–1 win v Newport County on 18 August 1951. He played in both inside forward and wing half positions in making 39 appearances scoring 6 goals in 1951–52. The following season Bristol City rose to 5th place in the Third Division South, near neighbours Bristol Rovers finished as champions, Williams made 42 appearances outscoring John Atyeo with 17 goals including a hat-trick in a 5–0 win v Crystal Palace on 13 September 1952. In 1953–54 Williams played first at left half then at inside left making 39 appearances scoring 4 goals with Bristol City rising to 3rd place. When Bristol City won promotion as Third Division South champions in 1954–55 Williams again made 39 appearances scoring 4 goals starting at inside left and ending as left half. In 1955–56 in the Second Division Williams played regularly as left half making 34 appearances and 3 goals. The following season in 1956–57 Williams made 22 appearances scoring 8 goals but only made 3 appearances in his final season at Bristol City in 1957–58.
 Passage 3:Henri first appeared on stage in 1879 at the age of 15 with Florence St. John's Opera Company, performing in Jacques Offenbach's Madame Favart at the Strand Theatre and Edmond Audran's Olivette at the Avenue Theatre, both in 1880, in the latter of which she played a small role. She appeared in other operettas with St. John but left in 1881 to help Lytton begin his acting career. They joined the company at Philharmonic Theatre, Islington in several plays, including The Obstinate Bretons and The Shaughraun by Dion Boucicault, and then, with Kate Santley, played at the Royalty Theatre. There they appeared in Ixion, or the Man at the Wheel by F. C. Burnand, but the theatre closed soon afterwards. Henri rejoined St. John's company, playing in Bucalossi's Les Manteaux Noirs at the Avenue Theatre in 1882. She then rejoined Santley's company at the Royalty in 1883 in The Merry Duchess, but Lytton was out of acting work all this time and was forced to take a variety of odd jobs. Henri then played in the lavish 1883 Christmas pantomime of Cinderella at the Theatre Royal, Drury Lane. Henri and Lytton married in early 1884, both aged 19, at St. Mary Abbot's Church, Kensington. Neither family attended the ceremony.
