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: What job did Manny Shinwell hold the year Morris went to the West Indies? Passage 1:Between 1980 and 1988, the conflict intensified as the Iran–Iraq War commenced. One of the groups targeted in particular by Iraqi authorities were the Feyli Kurds, a community of Shi'ite Kurds settled in the southern area of the Zagros Mountains near Iraq's border with Iran. Saddam Hussein considered the group as 'Iranians' and began a campaign to drive the settlers out of the area as a part of his 'Arabization' policy in 1980., Saddam Hussein was severely critical of the Kurdistan Democratic Party (KDP) as they aligned forces with Iran in the conflict. In 1983, to avenge this liaison, he ordered the Army to abduct as many as 8,000 men and boys from Erbil province, where the clan of Barzani Kurds was based. Massoud Barzani, the leader of the clan and the KDP, himself lost 37 members of his family to the Iraqi troops. They were reported to having been sent to Nugra Salman prison in the southern deserts of Iraq, where they were tortured. Subsequently, the remains of 512 Barzani men were discovered in a mass grave. On March 16, 1988, Iraqi troops began shelling the Kurdish town of Halabja, in retaliation for an attack on Iraqi positions carried out by Iranian Revolutionary Guards and the aligned Peshmerga fighters. Subsequently, the town was attacked with a mix of chemical substances such as VX (nerve agent), sarin and mustard gas (see Halabja chemical attack). Over 5,000 people are believed to have been killed in the attack, which was considered to be a part of the Al-Anfal Campaign, directed against Kurds by the government under the command of Ali Hassan al-Majid, head of the Northern Bureau of the Ba'ath Party.
 Passage 2:From 1931, Hermes studied mathematics, physics, chemistry, biology and philosophy at the University of Freiburg.

After that he went on a scholarship to the University of Göttingen and then became an assistant at the University of Bonn.

At the end of the war he moved to Toplitzsee, where he was tasked with working on new encryption methods. In 1947, he became a lecturer at the University of Bonn where he took his habilitation, his thesis called Analytical manifolds in Riemannian areas. In 1949 he became a Professor at the University of Münster, where he turned back to the subject of mathematical logic.
