Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.

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

Now, solve this instance: Question: Who was Thor's alter ego? Passage 1:In 1860 Binding moved to Göttingen where he studied history and jurisprudence. After a short stay in Heidelberg, where he won a law prize, he moved back to Göttingen to finish his studies. In 1864 he completed his habilitation paper in Latin about Roman criminal law and lectured in criminal law at Heidelberg University. Two years later he was appointed professor of law of state and criminal law and procedure in Basel, Switzerland. In the same year he married Marie Luise Wirsing and published Das burgundisch-romanische Königreich and Entwurf eines Strafgesetzbuches für den Norddeutschen Bund. At this time he also became friends with Johann Jacob Bernoulli - an archaeologist, Jakob Burckhardt - an art historian, and Friedrich Nietzsche - a philosopher. In August 1867 his first son, Rudolf Georg, was born, followed two years later by his second son. Rudolf G Binding later became a famous writer. Karl Binding and his wife were to have one more son and two daughters. In 1869 his family moved to Freiburg, and Binding volunteered to fight in the Franco-Prussian War. Although his lack of military training meant he was unable to serve as a soldier, he was accepted as an orderly and posted to the front, serving in a field hospital. In 1872 he took on a post at the Reichs University in Straßburg. In the same year he moved to Leipzig University, where he was to continue to work for the next 40 years. From 1879 until to 1900 Binding worked in the district court of Leipzig. After becoming Leipzig University's rector and receiving his emeritus, he moved to Freiburg, where his wife died only a few days later at 71 years old. In 1918, during the First World War, Binding left Germany to lecture German soldiers in Macedonia and Bulgarian intellectuals in Sofia.
 Passage 2:Defeating the aliens, Thor shares a double life with his alter ego: treating the ill in a private practice with nurse – and eventual love – Jane Foster, and defending humanity from evil. Thor's presence on Earth almost immediately attracts the attention of his adoptive brother and enemy Loki. Loki is responsible for the emergence of three of Thor's principal foes: the Absorbing Man; the Destroyer, and the Wrecker. On one occasion, Loki's tactics were accidentally beneficial – although successful in using an illusion of the Hulk to draw Thor into battle, it results in the formation of the superhero team the Avengers, of which Thor is a founding and longstanding member. Thor's other early foes include Zarrko, the Tomorrow Man; the Radioactive Man; the Lava Man; the Cobra; Mister Hyde; the Enchantress and the Executioner, and the Grey Gargoyle.
 Passage 3:Latin pop became the most popular form of Latin music in the United States during the 1980s and 1990s, with acts such as Puerto Rican boyband Menudo, even achieving massive crossover success among non-Latino listeners during the late 1990s. While not restricted to America by any means, Latin pop was profoundly affected by production techniques and other styles of music — both Latin and otherwise — that originated primarily in the United States. Tejano music, centered in Texas and the U.S./Mexico border region, had begun to introduce synthesizers, slicker production, and a more urban sensibility to formerly root styles like norteño and conjunto. Moreover, New York and Miami were home to thriving Latin club scenes, which during the 1980s led to the rise of Latin freestyle, a club-oriented dance music that was rooted in Latin rhythms but relied on synthesizers and drum machines for most of its arrangements. Both of these sounds influenced the rise of Latin pop, which retained Latin rhythms in its uptempo numbers but relied more on mainstream pop for its melodic sense.
