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: Which of the actors as Thomas Edison and George Westinghouse as of September 24, 2015 is older? Passage 1:The main reasons for Cleveland's return into politics were his desire to prevent New York Governor David B. Hill (a political rival of Cleveland's who also wanted the 1892 Democratic nomination) from winning the Democratic Presidential nomination that year and Cleveland's staunch opposition to free silver, a prominent political issue back then. Cleveland considered Governor Hill to be a corrupt machine boss, and he staunchly believed that the Democrats should maintain their support of the gold standard. Cleveland hired former U.S. Navy Secretary William C. Whitney as his campaign manager that year. Cleveland and Whitney frequently contacted Southern politicians and newspaper editors in an attempt to get them to support Cleveland's 1892 Presidential bid. Cleveland portrayed himself as a candidate who can unify the Democratic Party (due to his status as a former President and the only Democrat elected U.S. President since the U.S. Civil War) and tried appealing to Southerners by opposing federal oversight of African American voting rights. Whitney also fundraised huge amounts of cash from wealthy bankers and businessmen in order to finance Cleveland's Presidential campaign. An attempt by New York Democratic Party chairman Edward Murphy to strengthen Governor Hill's chances for the 1892 Democratic nomination by giving him all of New York's delegates backfired and ended up helping Cleveland (since most of the delegates from the other states ended up supporting him afterwards). When the 1892 Democratic National Convention convened on June 21, 1892, in Chicago, Cleveland was narrowly able to win the Democratic party nomination for U.S. President on the first ballot.
 Passage 2:Following the invasion of Poland in 1939 most of the 3.5 million Polish Jews were rounded up and put into newly established ghettos by Nazi Germany. The system was intended to isolate the Jews from the outside world in order to facilitate their exploitation and abuse. The supply of food was inadequate, living conditions were cramped and unsanitary, and the Jews had no way to earn money. Malnutrition and lack of medicine led to soaring mortality rates. In 1941, the initial victories of the Wehrmacht over the Soviet Union inspired plans for the German colonisation of occupied Poland, including all territory within the new district of General Government. At the Wannsee Conference held near Berlin on 20 January 1942, new plans were outlined for the genocide of the Jews, known as the "Final Solution" to the Jewish Question. The extermination programme was codenamed Aktion Reinhard in German, to differentiate it from the Einsatzgruppen mass killing operations in territories conquered by Nazi Germany, in which half a million Jews had already been annihilated.
 Passage 3:Michael Mitnick began writing the script for The Current War in 2008, basing it on the real life "war of the currents" AC/DC conflict between Edison and Westinghouse. The screenplay is the conclusive result of sixty drafts, a ten-year writing process, first as a musical and finally as a film. In 2011 Mitnick's screenplay made the Black List, an industry survey of "most liked" screenplays not yet produced. On May 3, 2012, it was reported that Timur Bekmambetov's company, Bazelevs, had acquired the rights to Mitnick's screenplay. Bekmambetov was set to direct. On March 31, 2014, it was reported that Ben Stiller was in negotiations to direct the film. As of September 24, 2015, Benedict Cumberbatch and Jake Gyllenhaal were in talks to play Thomas Edison and George Westinghouse, respectively, with Alfonso Gomez-Rejon (Me and Earl and the Dying Girl) eyed to direct the film. Sacha Baron Cohen was also briefly linked to the role of Edison. On September 29, 2016, Michael Shannon was cast as Westinghouse, and on October 4, Nicholas Hoult was cast as Nikola Tesla. In November 2016, Katherine Waterston and Tom Holland joined the cast. The following month, Tuppence Middleton and Matthew Macfadyen were cast.
