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 input: 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.

Q: Question: What was the age difference between Marie-Félix Blanc's parents? Passage 1:After arriving in Vienna, Lendvai soon started looking for work, at first limited by lack of sufficient language skills. In this period he helped foreign correspondents with matters relating to Hungary and wrote smaller articles under aliases such as "György Holló", "Árpád Bécs" or "Paul Landy". Lendvai soon overcame early difficulties and was naturalized in Austria in 1959, and became a journalist and commentator on Eastern Europe. He was the correspondent for Eastern Europe of the daily Die Presse and the Financial Times for twenty-two years. He also contributed to The Economist and wrote columns for Austrian, German and Swiss newspapers and radio stations. In 1982 Lendvai became editor-in-chief at the Eastern Europe department of the ORF public broadcasting company and director-general of Radio Österreich International in 1987. His weekly columns were published by the newspaper Der Standard. In 1985, a Cultural Forum dubbed the East-West summit was organized by the Hungarian communist leadership, to which 900 politicians, writers and other notable people were invited. At the same time a "counter cultural forum" was planned with expected participation of "dissidents and opposition groups". György Konrád was one of the intended speakers. In 2010, a Hungarian pro-government newspaper accused Paul Lendvai of collaboration with the communist regime by having provided information about the counter-forum to the Hungarian authorities. Socialist ex-prime minister Ferenc Gyurcsány came to Paul Lendvai's defence, saying "As for me, I support him in his struggle to make a case for his decisions of yesteryear. ... And we've got to stop digging up the past." György Konrád, one of the intended speakers of the opposition event, said: "If this was how things were, then it is very sad" about Lendvai providing the information. Lendvai rejected the accusations and said that the campaign against him was due to his criticism of the present government in his latest book. Former conservative MP Debreczeni, noted philosopher Sandor Radnoti, Austrian conservative leader Erhard Busek defended his integrity. János Nagy, the ambassador whom Lendvai talked to at the time, was interviewed about the matter on Klubrádió and insisted that his reports always faithfully rendered what was said. An article printed in left-wing Népszabadság agrees with Lendvai's defense that he was not an agent, although it goes on to stress that he was nonetheless a willing and active collaborator to the Communist regime.
 Passage 2:The strains between Southampton's religion and the Elizabethan regime first became apparent when in February 1569 Southampton's brother-in-law, Sussex, wrote to Sir William Cecil urging that Southampton be 'rather charitably won than severely corrected'. That summer Queen Elizabeth was Southampton's guest at Titchfield Abbey, but in November both Southampton and his father-in-law, Viscount Montague, were implicated in the Northern Rebellion. In a letter dated 1 December 1569 the Spanish ambassador, Guerau de Spes, wrote to the Duke of Alba that both Montague and Southampton 'have sent to me for advice as to whether they should take up arms or go over to your Excellency'. According to Akrigg, Montague and Southampton set sail for Flanders, but were driven back by contrary winds. Although they were ordered to come immediately to court to explain their actions, to all appearances things were smoothed over, and neither Southampton nor his father-in-law was punished for his involvement. However matters came to a head in May 1570 when Pope Pius V excommunicated the Queen, and English Catholics were required to choose between loyalty to religion and loyalty to the sovereign. Southampton sought counsel from John Lesley, Bishop of Ross, at a secret meeting in the marshes of Lambeth, where they were intercepted by the watch, and in consequence, on 18 June 1570 the Privy Council ordered Southampton's arrest and confined him to the house of Henry Becher, Sheriff of London. On 15 July he was placed in the custody of Sir William More at Loseley, where More was under instructions to induce Southampton to take part in Protestant devotions in the household. After doing so, Southampton was released in November.
 Passage 3:Marie-Félix Blanc was born on 22 December 1859 in Paris to French businessman François Blanc and his second wife, Marie Charlotte Hensel. Her father was the founder of the Société des bains de mer de Monaco and operated multiple casinos, including the Casino de Monte-Carlo in Monaco and the Bad Homburg vor der Höhe Casino in Germany. Her godfather, Count Antoine Bertora, was rumored to be her biological father. She had an older sister, Louise; an older brother, Edmond; and two older half-brothers from her father's first marriage to Madeleine-Victoire Huguelin, Camille and Charles. Her older sister later married Prince Constantine Wincenty Maria Radziwiłł. Her older brother later served as the mayor of La Celle-Saint-Cloud and her older half brother, Camille, served as mayor of Beausoleil. When she was 18 years old, Blanc's father died, leaving her a vast inheritance.
