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.
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.

Problem: Question: In what year did Mickey Cochrane lead the American League in putouts? Passage 1:By the start of the 1926 season, Cochrane was already considered the best catcher in the major leagues. He won the American League Most Valuable Player Award, mostly for his leadership and defensive skills, when he led the American League in putouts and hit .293 along with 10 home runs and 58 runs batted in. Cochrane was a catalyst in the Athletics' pennant-winning years of 1929, 1930 and 1931, during which he hit .331, .357 and .349 respectively. He played in those three World Series, winning the first two, but was sometimes blamed for the loss of the 1931 World Series, when the St. Louis Cardinals, led by Pepper Martin, stole eight bases and the Series. However, in his book The Life of a Baseball Hall of Fame Catcher, author Charlie Bevis cites the Philadelphia pitching staff's carelessness in holding runners as a contributing factor. Notwithstanding this, the blame for the 1931 World Series loss dogged Cochrane for the rest of his life.
 Passage 2:Through the Cold War, the United States, Soviet Union and other countries contemplated the possibility of nuclear warfare. While previous technology had developed to protect the crews of armored vehicles from projectiles and from explosive damage; the possibility of radiation arose. In the NATO countries little if any development took place on defining a doctrine of how to use armed forces without the use of tactical nuclear weapons. In the Soviet sphere of influence the legacy doctrine of operational maneuver was being theoretically examined to understand how a tank-led force could be used even with the threat of limited use of nuclear weapons on prospective European battlefields. The Warsaw Pact arrived at the solution of maneuver warfare while massively increasing the number of anti-tank weapons. To achieve this, Soviet military theorists such as Vasily Sokolovsky (1897-1968) realized that anti-tank weapons had to assume an offensive role rather than the traditionally defensive role of the Great Patriotic War (1941-1945) by becoming more mobile. This led to the development of improved guided anti-tank missiles, though similar design work was being performed in Western Europe and the United States.
 Passage 3:Due to his actions during the battle, former Army Captain William D. Swenson was recommended to receive the Medal of Honor by Marine General John R. Allen. Having been critical of the officers superior to him during the battle, he left the Army in February 2011. A 2012 investigation by McClatchy News Service concluded that the justification for Meyer's decoration may have been inflated and that the nomination for Swenson's Medal of Honor may have been intentionally lost. Meyer disputes McClatchy's allegations in his book, Into the Fire: A Firsthand Account of the Most Extraordinary Battle in the Afghan War. In August 2012, California Representative Duncan D. Hunter wrote to Secretary of Defense Leon Panetta regarding the Medal of Honor nomination of Swenson, comparing his case to that of Sgt. Rafael Peralta. In January 2013, Representative Hunter said Swenson's nomination had been awaiting President Barack Obama's approval at the White House since at least July 2012. Representative Hunter stated he was considering seeking an inspector general inquiry due to the delay. Swenson was awarded the Medal of Honor on October 15, 2013.
