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: Who found the political party that Slobe joined in 1942? Passage 1:Elysium was produced by Bill Block, Neill Blomkamp, and Simon Kinberg, and written and directed by Neill Blomkamp, the director and co-writer of District 9 (2009). It reunites Blomkamp with some of his District 9 crew, such as editor Julian Clarke, production designer Philip Ivey, cinematographer Trent Opaloch, and actor Sharlto Copley, playing one of the film's antagonists. Elysium is a co-production of TriStar Pictures and MRC. Although the film's story is set in 2154, Blomkamp has stated that it is a comment on the contemporary human condition. "Everybody wants to ask me lately about my predictions for the future," the director has said, "No, no, no. This isn't science fiction. This is today. This is now." In January 2011, independent studio Media Rights Capital met with major studios to distribute Elysium, and Blomkamp shared art designs of his proposed science fiction film. The art designs won over the executives at Sony Pictures, who bought the film after making a more attractive offer than the other studios. With a production budget of , production began in July 2011. The film's Earth-bound scenes were shot in a dump in the poor Iztapalapa district on the outskirts of Mexico City, while the scenes for Elysium were shot in Vancouver and the wealthy Huixquilucan-Interlomas suburbs of Mexico City. Matt Damon shaved his head for the role of Max. The main role was first offered to Watkin Tudor Jones (aka Ninja), a South African rapper, who despite being a fan of District 9 (he has a D9 tattoo on his inner lip) did not take the role. The role was then offered to rapper Eminem, but he wanted the film to be shot in Detroit. That was not an option for the two studios, so Blomkamp moved on to Damon as his next choice. Futuristic designs were executed by Philip Ivey after long periods of researching and studying older science fiction films. Ivey has continuously cited Syd Mead as a substantial influence for the film. Weta Workshop created the exosuits for Damon and Copley's characters, while the complicated visual effects were handled primarily by Image Engine (who also collaborated on District 9) with additional work by Whiskytree, MPC, The Embassy and Industrial Light and Magic. Re-shoots took place through October 2012. The film's music score was composed by newcomer Ryan Amon and recorded at Abbey Road Studios with the Philharmonia Orchestra. The soundtrack was released on August 6, 2013.
 Passage 2:Slobe was born in Pittsburgh to a well-to-do Jewish family, and grew up in Chicago, enrolling in the School of the Art Institute of Chicago at 16; by 19 she was exhibiting paintings and winning prizes. She began exhibiting sculpture as well by the late 1930s, and came eventually to be known more as a sculptor than as a painter. In 1939 and 1940 she worked for the Works Progress Administration, creating art and teaching in a number of states, including Oregon. She became acquainted at this point with George Perle, whom she married in 1940; in 1942 the couple joined the Socialist Workers Party, and she took the pseudonym "Laura Gray". She was soon tasked with assisting in the organization of automotive workers, and it was at this time that she began her cartooning career. Encouraged to submit drawings to The Militant, her first appeared in the paper on March 4, 1944; she went on to become the paper's staff artist, submitting at least one cartoon almost weekly for the rest of her life. These drawings, which have been compared to the work of Boardman Robinson, Hugo Gellert, and Robert Minor, would be published in Trotskyist publications around the world. Some of her cartoons on the subject of civil rights would also be published in the African-American press.
 Passage 3:Major Granville O. Haller of the 4th Infantry led an expedition from Fort Dalles into central Washington, and Lieutenant William A. Slaughter also of the 4th Infantry with forty-eight men from Fort Steilacoom crossed Natchez Pass to aid Major Haller when attempts to move the Indians of Puget Sound onto reservations caused trouble between them and some white settlers. Captain Maloney of the 4th Infantry, and Captain Gilmore Hayes of the Washington Volunteers had started for Yakima via Natchez Pass when they were overtaken on 29 October 1855 by the Nisqually tribe under Chief Leschi. Lt. Slaughter and his men plus Captain Hayes' force met the Indians at the crossing of the White River, and on 4 November 1855 fought without decisive results. The following day the troops met hostiles in the difficult country between the White and Green Rivers. The troops fell back into the valleys and on 24 November 1855, Lt. Slaughter, commanding a platoon of the 4th Infantry and a company of volunteers, was attacked in his camp at Puyallup. The lieutenant moved to the present site of Auburn and here again the Indians attacked. Slaughter and two corporals of the volunteer company were killed, four other men were injured, one later dying of his wounds. For years the town, which sprang up on this site, was known as Slaughter in honor of this officer of the 4th Infantry; it was later changed to Auburn.
