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: Of the two bandmembers that left P-Funk with Haskins, which was the oldest? Passage 1:The Channel is of geologically recent origin, having been dry land for most of the Pleistocene period. Before the Devensian glaciation (the most recent glacial period, which ended around 10,000 years ago), Britain and Ireland were part of continental Europe, linked by an unbroken Weald–Artois anticline, a ridge that acted as a natural dam holding back a large freshwater pro-glacial lake in the Doggerland region, now submerged under the North Sea. During this period the North Sea and almost all of the British Isles were covered by ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian ice sheets that joined to the north, blocking its exit. The sea level was about lower than it is today. Then, between 450,000 and 180,000 years ago, at least two catastrophic glacial lake outburst floods breached the Weald–Artois anticline.
 Passage 2:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.
 Passage 3:Kim Hong-il (23 September 1898 – 8 August 1980) was a Korean independence activist and a general of the Second Sino-Japanese War and the Korean War, who later became a diplomat and politician in South Korea. Born in North Pyongan, he did his early schooling in China and Korea, and had a brief career as a teacher before his connections with the nascent Korean independence movement led to his imprisonment. He fled into exile in China in 1918, and served in the Kuomintang's National Revolutionary Army from 1926 to 1948, following which he moved to the newly-independent South Korea to join the Republic of Korea Army. He commanded South Korea's I Corps during the first year of the Korean War, and was then sent to Taipei as South Korea's ambassador to the Republic of China, which by then had retreated to Taiwan. His assignment there ultimately lasted nine years. He returned to South Korea in 1960 following the April Revolution which ended the rule of Syngman Rhee, and served briefly as Minister of Foreign Affairs under the Park Chung-hee junta. He ran for the National Assembly, first unsuccessfully in 1960 and 1963, and was then elected in 1967 and became a major figure in the opposition New Democratic Party.
