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: Did Holst's ten-year-old daughter have any siblings? Passage 1:When Joseph left Girton, the First World War was at a critical state; the Battle of the Somme had begun on 1 July 1916. Joseph wanted to assist the war effort, and after considering work on the land or in a munitions factory, took up part-time welfare work in Islington. In the autumn of 1916 she began teaching at Eothen, a small private school for girls in Caterham, founded and run by the Misses Catharine and Winifred Pye. In 1917 Holst's ten-year-old daughter Imogen started at the school; soon, under Joseph's guidance the young pupil was composing her own music. Joseph extended her own musical activities by joining the orchestra at Morley College, where Holst was the director of music and where her brother Edwin had played the cello before the war. At first she played the double-bass, but later took French horn lessons, possibly from Adolph Borsdorf; later still, at very short notice, she taught herself the timpani part for a summer concert. By 1918 she was a member of the Morley committee that on 9 March organised and produced an opera burlesque, English Opera as She is Wrote, in which English, Italian, German, French and Russian opera styles were parodied in successive scenes. The performance was a great success and was repeated at several venues. It may have inspired Holst to use parody in his own opera, The Perfect Fool, which he began composing in 1918. In her spare time Joseph founded and ran a choir for Kensington nannies, which took part in local singing contests as the "Linden Singers".

He also chaired the steering committee for the RADIANCE trial from 1989-1992 which studied the use of digoxin in people who were also treated with ACE inhibitors and chaired the steering committee for the RENEWAL trial (1999-2002) for etanercept. He was also the co-PI of the PARADIGM-HF trial that led to the approval of valsartan/sacubitril.
