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: What is the name of the person that married the artist who performed at the 1970 Palermo Pop Festival? Passage 1:Filmed in technicolor format, the music video for "Nobody's Perfect" was shot at Nu Boyana Film studios in Sofia, Bulgaria, on 24 March 2011 and was directed by Emil Nava. The music video premiered on 14 April 2011 in the United Kingdom through Jessie's Vevo channel. The music video is inspired by Lewis Carroll classic tale Alice's Adventures in Wonderland, Jessie J sits in a banquet table similar to the Mad Hatters' tea party. Jessie J is shown in a hall of doors that gives a resemblance to the curious hall in the first chapter of Alice in Wonderland. Jessie J also rolls in tar and appears dressed as the Roman goddess Libertas, who is better known as the robed female figure of the Statue of Liberty, what could be interpreted as Black-and-white dualism. After completing the filming sessions, Jessie J described the video as her favorite done so far.
 Passage 2:Helped by his association with The Guardian, Cannon was able to contribute more substantial articles to the Los Angeles Times and the Chicago Sun-Times, and to underground magazines such as Creem. He wrote the 1970 documentary film London Rock, focusing on the UK's counterculture movement. He recalls that, together with Rolling Stone journalists David Dalton and Jonathan Cott, he joined Granada Television documentary-makers such as Jo Durden-Smith, John Sheppard and Michael Darlow in devising "prime-time networked shows designed as anthems of the revolution". Among these late-1960s projects, he says that the Johnny Cash at San Quentin TV special was his idea, and he "share[s] credit" for the ideas behind the concert films The Doors Are Open and The Stones in the Park. He also directed the film of Frank Zappa's performance at the 1970 Palermo Pop Festival, for RAI, Italy's national public broadcaster.
