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 succeeded Winston Churchill in the position he held in 1944? Passage 1:In June 1943, the head of the British Special Operations Executive mission in Greece, Brigadier Eddie Myers, conceived the Agreement of National Groups. Under the terms of the agreement, ELAS and the right-wing EDES and EKKA, united under a common general staff consisting of Myers and the leaders of the units, while also accepting the seniority of the British Middle East Command (General Henry Maitland Wilson). The accord was to pave the way for Operation Animals, part of Operation Barclay, a plan to deceive the Axis powers into believing that the Allied invasion of southern Europe would be in Greece and not Sicily. In late 1942, with on-going Allied success in the North African Campaign, the thoughts of the military planners turned to the next target. British planners considered that an invasion of France from Britain could not take place until 1944, and the Prime Minister, Winston Churchill, wanted to use the Allied forces from North Africa to attack Europe's "soft underbelly". There were two possible targets for the Allies to attack. The first option was Sicily; control of the island would open the Mediterranean Sea to Allied shipping and allow the invasion of continental Europe through Italy. The second option was into Greece and the Balkans, to trap the German forces present between the British and American invaders and the Soviets. At the Casablanca Conference in January 1943 Allied planners agreed on the selection of Sicily – codenamed Operation Husky – and decided to undertake the invasion no later than July that year. There was concern among the Allied planners that Sicily was an obvious choice – Churchill is reputed to have said "Everyone but a bloody fool would know that it's Sicily" – and that the build-up of resources for the invasion would be detected.
 Passage 2:Brought up on his grandfather's estate at Reddentin, where his uncle Gustav von Below was founding what would become the Pentecostal movement, von Blumenthal was educated at the military schools of Culm and Berlin. He entered the Guards as 2nd lieutenant in 1827. He studied at the Berlin General War School (later called the Prussian Military Academy). After serving in the Rhine Province, he joined the topographical division of the general staff in 1846. As lieutenant of the 31st foot, he took part in 1848 in the suppression of the Berlin riots, and in 1849 was promoted captain on the general staff. The same year he served on the staff of General Eduard von Bonin in the First Schleswig War, and so distinguished himself, particularly at Fredericia, that he was appointed chief of the staff of the Schleswig-Holstein army, when the previous chief of staff, Captain von Delius, was killed.
 Passage 3:Sanders was selected in the second round (47th overall) of the 1995 NFL Draft by the Arizona Cardinals. As a rookie, he started all 16 games, and recorded 52 receptions for 883 yards and two touchdowns. During Week 6, in a 27-21 loss to the New York Giants he recorded six receptions for 108 yards and the only two touchdowns of the season. In 1996, he recorded 69 receptions or 813 yards and four touchdowns. In 1997, he recorded 75 receptions for 1,017 yards and four touchdowns. In 1998, he experienced his best season statistically. He led the team in receptions (89) and receiving yards (1,145) and three touchdowns. In 1999, he recorded 79 receptions for 954 yards and one touchdown. In 2000, he recorded 54 receptions for 749 yards and a career-high in touchdowns (6). In 2001, he recorded 41 receptions for 618 yards and two touchdowns. In 2002, his final with the Cardinals, he recorded a Cardinals' career low in receptions (34) and receiving yards (400), and two touchdowns.
