Given the task definition, example input & output, solve the new input case.
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.

New input case for you: Question: Which manager of Port Vale FC had the best record during the 1950s? Passage 1:On 26 July 1830, the revolution of the so-called Three Glorious Day (or July Revolution) erupted due to the authoritarian and anti-Gallican tendencies showed by Charles X and his Prime Minister Jules de Polignac, expressed by the recently approved Saint-Cloud Ordinances. Despite the abdication of Charles X and the Dauphin Louis in favor to Charles X's grandson Henri, Duke of Bordeaux, on 2 August 1830, only seven days later Louis Philippe I, still Duke of Orléans, was elected by the Chamber of Deputies as new "King of the French". The enthronement of Louis Philippe was strongly wanted by Doctrinaires, the liberal opposition to Charles X's ministries, under the concept "nationalize the monarchy and royalize France". On 14 August 1830, the Chamber approved a new Constitution, who became the de facto political manifesto for the Orléanists, containing the basis for a constitutional monarchy with a central Parliament. The Orléanism, became the dominant tendency within political life, easily divided inside the Chamber of Deputies between the centre-left of Adolphe Thiers and the centre-right of François Guizot. Louis Philippe showed himself more aligned with Guizot, entrusted to the higher offices of government, and rapidly became associated with the rising "new men" of the banks, industries and finance, gaining the epithet of "Roi bourgeois". In the early 1840s, Louis Philippe's popularity decreased, due to his strong connection to upper classes and repression against workers' strikes, and showed few concerns for his weakened position, leading the writer Victor Hugo to describe him as "a men with many little qualities". The Orléanist regime finally fell in 1848, when a revolution erupted and on 24 February Louis Philippe abdicated in favor to his grandson Philippe, Count of Paris, under regency of his mother Helene, Duchess of Orléans, who was quickly ousted out from the Chamber of Deputies during the regency's formalization, who was interrupted by republican deputies who instead proclaimed the Second Republic.
 Passage 2:In 1851, she met Elizabeth Cady Stanton, who became her lifelong friend and co-worker in social reform activities, primarily in the field of women's rights. In 1852, they founded the New York Women's State Temperance Society after Anthony was prevented from speaking at a temperance conference because she was female. In 1863, they founded the Women's Loyal National League, which conducted the largest petition drive in United States history up to that time, collecting nearly 400,000 signatures in support of the abolition of slavery. In 1866, they initiated the American Equal Rights Association, which campaigned for equal rights for both women and African Americans. In 1868, they began publishing a women's rights newspaper called The Revolution. In 1869, they founded the National Woman Suffrage Association as part of a split in the women's movement. In 1890, the split was formally healed when their organization merged with the rival American Woman Suffrage Association to form the National American Woman Suffrage Association, with Anthony as its key force. In 1876, Anthony and Stanton began working with Matilda Joslyn Gage on what eventually grew into the six-volume History of Woman Suffrage. The interests of Anthony and Stanton diverged somewhat in later years, but the two remained close friends.
 Passage 3:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.
