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.

The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input case for you: Question: Did Rudolf have any cousins on his mother's side? Passage 1:An ensemble of 20 actors make up the bulk of the series' cast. Hawley found ensembles enticing because they presented "a lot of really good moving pieces". At Paleyfest 2015, the Fargo creator commented: "It's sort of like a horse race in a way, especially when you know that everyone is on this collision course. It's like, 'Who's going to make it?' And you can put people together in unexpected pairings." Offerman played Karl Weathers, an alcoholic and the only lawyer in Luverne, and Cristin Milioti was assigned the part of Betsy Solverson, Lou's terminally ill wife. Hawley felt that Milioti was the right choice because her personality was similar to her character's. Garrett portrays Joe Bulo, and Bokeem Woodbine appears as Mike Milligan, a role he was offered two days after auditioning. For the role of Hanzee Dent, Hawley hired Zahn McClarnon two weeks after his audition. Six others play members of the Gerhardts: Kieran Culkin as Rye, Rachel Keller as Simone, Michael Hogan as Otto, Allan Dobrescu as Charlie, Angus Sampson as Bear, and Jeffrey Donovan as Dodd. When asked about his decision to cast Donovan, Hawley told the actor, "I don't know. You just come off with a sense of power. I think Dodd comes off with a sense of power, and I thought that you have the chops to find the humor in it." Donovan gained 30 pounds in preparation for his role. Other major supporting roles in Fargo second season include: Bruce Campbell as Ronald Reagan, Keir O'Donnell as Ben Schmidt, and Elizabeth Marvel as Constance Heck.
 Passage 2:"James Metcalfe - Of the many fine players who figured in Trinity's ranks in the early N.U. days was one who gave outstanding service to the club and in whom the players could always have supreme confidence on the last line of defence. Jimmy Metcalfe soon won recognition as one of the finest full-backs in the country. Born in Cumberland, Jimmy's early football was with Askham-in-Furness (sic Askam-in-Furness), with whom he started in 1890 under R.U. rules. His first club in Yorkshire was Barnsley R.U. and thence to Featherstone. Whilst there, in season 1896-7, he played twice for North v. South - these being R.U. trial matches - and in that season too he figured in all Yorkshire's R.U. county games. It was later - but still in 1897 - that he turned to the Northern Union code and joined Trinity. Here his distinctions were continued and he was a member of the Yorkshire N.U. side which won the County Championship of 1897-8 and again in 1898-9. We can hardly do justice to his fine career in what must necessarily be a short account, but mention must be made of the fact that he played in Trinity's successful Cup Final at Headingley Rugby Stadium, Leeds in 1909, when he was thirty-six years old. And that was not the end. He did not cease to play until 1911 and, in his last match for Trinity gave a final display of his goal-kicking ability by adding three to his wonderful record. Jimmy's record of kicking eleven goals in a match has been equalled twice, but never extended. He set up the record on April 6, 1909, against Bramley at Belle Vue. Trinity's score was 11-15-67 to 2-2-10." 
 Passage 3:Another opportunity for a Habsburg gain in power opened when in 1306 King Wenceslaus III, the last Bohemian ruler of the Přemyslid dynasty, was killed and Albert I as rex Romanorum was able to seize his kingdom as a reverted Imperial fief. Rudolph was vested with the Bohemian throne, however contested by his maternal uncle Henry of Gorizia, Duke of Carinthia and husband of Wenceslaus' sister Anne. When several Bohemian nobles elected Henry King of Bohemia, Albert I placed his brother-in-law under the Imperial ban and marched against Prague. Henry fled, first to Bavaria, then back to his Carinthian homelands. To further legitimate the Habsburg claims to the Bohemian and the Polish throne, Albert had Rudolph married to Princess Elizabeth Richeza of Poland, a member of the Piast dynasty and widow of the predeceased King Wenceslaus II.
