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 modern day country is Strasbourg part of? Passage 1:Raffaello de Banfield attended the Swiss International "Lyceum Alpinum Zuoz", the "Dante Alighieri" Lyceum in Trieste, the University of Bologna and the Benedetto Marcello Conservatory in Venice led by Gian Francesco Malipiero. He studied composition from 1946 to 1949 at the National Conservatory (under the direction of Henri Busser) with Nadia Boulanger in Paris. In these years he met Herbert von Karajan with whom he had a lifelong friendship, and also with artists such as Pablo Picasso, Jean Cocteau and Francis Poulenc. In the United States he belonged to the intellectual circle surrounding the writer and composer Paul Bowles, through which he met Tennessee Williams and Leonard Bernstein. In 1949 through the painter Leonor Fini he was introduced to the choreographer and ballet dancer Roland Petit; out of this grew the ballet Le combat ("The Duel"), which had its first original production in London in 1949. This piece, based upon the Tancred and Clorinda episode in Torquato Tasso's poem Gerusalemme liberata, was performed 39 times at the Vienna State Opera in the choreography of Dimitrije Parlic between 1959 and 1973. Until 1958 he spent time between Paris and New York and maintained a friendship also with Maria Callas. After years abroad in Italy, France, England and the United States, where he lived for more than ten years, he was from 1972 to 1996 Director of the Giuseppe Verdi Theatre in Trieste and he comprehensively renovated and modernised the Opera House. From 1978 to 1986 he was Director of the "" ("Festival of the two worlds") in Spoleto, Italy.
 Passage 2:On 4 June 1799, the First Battle of Zurich was fought between André Masséna's 45,000-strong Army of the Danube and a 53,000-man Austrian army led by Archduke Charles, Duke of Teschen. Austrian casualties numbered 2,400 and eight guns while the French lost 4,400 men and 28 guns. Though the French held their ground, Masséna evacuated Zürich the next day and withdrew to a strong position overlooking the city. Altogether, Masséna commanded 76,781 troops. In Switzerland were infantry divisions under Claude Lecourbe (1st), Joseph Chabran (2nd), Jean-de-Dieu Soult (3rd), Jean Thomas Guillaume Lorge (4th), Jean Victor Tharreau (5th), François Goullus (6th), Joseph Souham (7th) and Louis Marie Turreau (Valais), a cavalry division under Louis Klein and an infantry reserve under Jean Joseph Amable Humbert, plus occupation troops. The 6th and 7th Divisions were supervised by Pierre Marie Barthélemy Ferino while Lecourbe controlled the 1st and 2nd. Included in Masséna's command were Claude Juste Alexandre Legrand with 6,186 men and Claude-Sylvestre Colaud with 5,106 men watching the Rhine north of Strasbourg. Opposed to the French were 85,000 troops led by Charles, including a force watching the French divisions on the Rhine to the north and eight battalions under Gottfried von Strauch near the Saint Gotthard Pass in the south.
 Passage 3:Colby Carthel, who had played linebacker for the Angelo State Rams from 1996 to 1999, was named the A&M–Commerce head coach in January 2013, following the resignation of Morriss in November 2012. During the 2013 season, the team upset NCAA Division I FCS team Houston Baptist, 55–21. In December 2013, three Lions football players were named to the All-Super Region Four team: defensive end Charles Tuaau (first team), as well as wide receiver Vernon Johnson and defensive end Tevin Moore (second team). Darvin Peterson and Tuaau were the fifth and sixth Lions to be named to the AFCA All-America first team when they accomplished the feat in 2006 and 2013, respectively. During the 2014 season, the Lions set a Division II record for total offense when they accumulated 986 yards against East Texas Baptist in a 98–20 win. Lions football players of this era who went on to play in the National Football League include Cedric Bonner, who signed with the Atlanta Falcons in 2005, and 2012 Lone Star Conference (LSC) Linebacker of the Year Danny Mason, who signed with the Denver Broncos in 2015.
