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.

New input case for you: Question: What city did Madonna perform in on March 1, 2015? Passage 1:MS Al Andalus Express (formerly Nord Pas-de-Calais) is a freight ferry owned by Eurotunnel and operated by FRS Iberia/Maroc. She was built in 1987 by Chantiers du Nord et de la Mediterranee, Dunkirk (Yard No 325) for Societe Nationale des Chemin de Fer Francais (SNCF), Paris as a multi-purpose passenger and roll-on roll-off ferry for lorries and railway vehicles. After the introduction of Eurotunnel there was no need for a train ferry, so SNCF was losing money running her. She was acquired by SNAT and Stena Sealink in 1989, which operated the Nord Pas-de-Calais until 31 December 1995. From 1 January 1996 SNAT operated as SeaFrance. The vessel was renamed SeaFrance Nord Pas-de-Calais. SeaFrance operated until November 2011, and was liquidated on 9 January 2012. Eurotunnel won the bid for the three of the former SeaFrance vessels the original name of the vessel was restored, dropping the SeaFrance prefix. MyFerryLink started running on 20 August 2012, although Nord Pas-de-Calais joined in November 2012 following a refit. Following MyFerryLink's cessation of operations, mostly cited due to financial issues, the ferry was used directly by Eurotunnel to carry hazmat cargoes that are not allowed on regular train services.
 Passage 2:Lange was born in Warsaw into the patriotic Jewish family of Henryk Lange (1815–1884) and Zofia née Eisenbaum (1832–1897). His father took part in the November Uprising against the Russian Partition of Poland. He was an admirerer of Romantic literature and its ideals. Antoni Lange enrolled at Warsaw University but around 1880 he was expelled for his patriotic activity by the Tsarist namiestnik Apuchtin who ruled the university at that time. He supported himself financially as a tutor but also published poetry under the pen-names Napierski and Antoni Wrzesień. He decided to study in Paris where he encountered new trends in literature, philosophy and art. In France he became familiar with the theories of Jean Martin Charcot, as well as Spiritualism, parapsychology, the philosophy of Arthur Schopenhauer and Friedrich Nietzsche, oriental religions, European and Eastern literature and modern literary criticism. He took part in the literary meetings of Stéphane Mallarmé.
 Passage 3:On March 1, 2015, Madonna performed the song for the first time on Italian TV show, Che tempo che fa, along with "Ghosttown", the album's second single. An episode featuring her appearance was aired on March 8. For the performance of "Devil Pray", Madonna wore "an extravagant black robe and various rosaries." A writer for Yahoo! noticed that both performances were warmly received by the audience, while Lionel Nicaise appreciated that Madonna put more emphasis on the melodies and her vocals during the performance, rather than costumes and stage props. Bianca Grace of Idolator noted that the performance "will have you repenting your weekend sins, as the singer emotionally sings the tune." "Devil Pray" was performed on Madonna's 2015–16 Rebel Heart Tour. Following the Last Supper-themed mashup performance of "Holy Water" and "Vogue", Madonna climbed down to the center stage to perform "Devil Pray"; during the performance she straddled one of her male dancers, who was dressed as a priest, and engaged in a dance-off with other dancers. Jordan Zivitz from the Montreal Gazette said that she found the performance to be "challenging". Previous to this the song was also used for promotional videos related to the tour's rehearsals and dancer interviews. The performance of "Devil Pray" at the March 19–20, 2016 shows in Sydney's Allphones Arena was recorded and released in Madonna's fifth live album, Rebel Heart Tour.
