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: Who was the lead design person for the German Type IXC submarines? Passage 1:Rafael Casanova i Comes () (Moià, 1660 – Sant Boi de Llobregat, 2 May 1743) was a Catalan jurist, and supporter of Charles VI, Holy Roman Emperor as a claimant to the Crown of Spain during the War of the Spanish succession. He became mayor of Barcelona and commander in chief of Catalonia during the Siege of Barcelona until he was wounded in combat while commanding La Coronela during the counterattack on the Saint Peter front on the last day of the siege, September 11, 1714. After the war he received a royal pardon for having supported the Habsburg claim to the Spanish throne. He recovered from his wounds, and continued his fight against absolute monarchy as a lawyer. It has been claimed that he is the author of the book Record de l'Aliança fet el Sereníssim Jordi Augusto Rey de la Gran Bretanya (Remembrance of the Alliance to George I of Great Britain) in which Catalonia reminds England of the Treaty of Genoa and their obligation to Catalonia.
 Passage 2:After the fourth single release "Willy Use a Billy... Boy", released in 1995 and peaked #5 in Austria, later in June 1996, both members left the band, due to a disagreement between Leigh and producer Brandes, who were quickly replaced by artists Jeane (Jeanette Macchi-Meier) and briefly Terence D'Arby (not to be confused with Terence Trent D'Arby), who himself again was replaced by Ché Jouaner. Thus it has been later revealed, that Brandes was the rapper on all E-Rotic releases, except on the first album, where he shared raps with Raz-Ma-Taz, such on "Take My Love", and Leigh still had to continue to provide vocal work for E-Rotic's four follow up studio albums The Power of Sex, Sexual Madness, the Abba cover album Thank You for the Music until 1999 to the Kiss Me studio album due to her contract. Also, raps on their first single "Max Don't Have Sex With Your Ex" were not done by Smith or Brandes, but instead were done by Marcus Thomas (aka Deon Blue) who would later join Pharao. Meanwhile, Leigh, alongside Raz-Ma-Taz, formed her own band S.E.X. Appeal in 1996. "He promised me a lot of things during my E-Rotic time, but never was willing to keep his promises. One of these promises was to produce a mixed video, with both cartoon and real people. We were never shown in the videos and so we had problems with our concerts, cause no-one really knew us as persons," Leigh revealed. On 27 June 1996, the group's second studio album The Power of Sex was released, preceded by the latter mentioned lead single "Willy Use a Billy... Boy" and followed by the singles "Help Me Dr. Dick", "Fritz Love My Tits" and "Gimme Good Sex", all becoming moderate chart hits, peaking at #18, #16 and #3 in Austria respectively. In 1996, E-Rotic were featured in the supergroup, called "Love Message", on the same titled, Masterboy-produced charity single "Love Message". They also appeared on the Queen tribute compilation album Queen Dance Traxx, with the song "Who Wants to Live Forever", which also saw a promotional release. The tribute album also featured another Queen song "We Are The Champions", recorded with all artists, who participated on Queen Dance Traxx as a supergroup labeled as "Acts United". In 1997, the studio albums "Sexual Madness" and the Abba cover CD Thank You for the Music was released with its single releases "Turn Me On", which peaked at #7 in Finland, "Thank You for the Music" and "The Winner Takes It All". The album Thank You for the Music was released under the artist name "Jenn and C." in France. Ironically the music video for "Gimme Good Sex" was also the first one, not being a comic video, but still it never aired and was banned from music channels because of being too controversial for its sexual content, thus Leigh, alongside Raz-Ma-Taz, left the band earlier, because she wanted to be shown in music videos.
