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-Lo 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 (18941973) 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 country was Victor Emmanuell III king of? Passage 1:In 1999, he was signed by Fiorentina for 28 billion lire (14.46 million), a team looking to expand and bring in better players, in an attempt to keep club captain and talisman Gabriel Batistuta. Despite making regular appearances in his first season for La Viola, Chiesa was fighting for a place with Predrag Mijatovic among others, and also had spells where he was out of form, and in the end only managed 6 goals in the league. In the 200001 season, Batistuta left for Roma and Fiorentina were plagued with injuries and financial problems. Meanwhile, Chiesa became the main striker for the club under manager Roberto Mancini, supported by playmaker Rui Costa, and scored 22 goals in 30 matches, finishing amongst the top 5 highest scorers in the league and helping Fiorentina to win the 200001 Coppa Italia over his former club, Parma, in the final; in the second leg at home, he set up Nuno Gomes's goal in a 11 draw, which allowed Fiorentina to clinch the title 21 on aggregate. The 200102 campaign proved to be a very difficult one: Chiesa started the campaign off strongly, scoring five goals in the first five matches of the season, but was ruled out for the rest of the season after sustaining a serious injury to his knee ligaments against Venezia on matchday five; left without Chiesa to lead the club's attack, Fiorentina were ultimately relegated at the end of the season. As a result of Fiorentina's relegation and financial troubles, Chiesa subsequently moved to Lazio for the following season, where he however failed to play at his personal best.
Passage 2:Between September 1943 and July 1944 "Felizitas" Beetz played a pivotal role in the so-called "Ciano operation". Galeazzo Ciano was Benito Mussolini's son-in-law. He served between June 1936 and his sacking by Mussolini on 5 February 1943 as Foreign Minister. Following the Grand Council vote of 24 July 1943 in which Ciano joined with the majority and opposed his father-in-law, voting to invite King Victor Emmanuel III to "resume his full constitutional powers", and the ensuing political take-over by General Pietro Badoglio, Ciano was on the receiving end of a vicious press campaign, deprived of a passport, and kept under virtual house arrest at his home in Italy. He began to fear for his personal safety and that of his family. On 27 August 1943 German intelligence arranged for Ciano and his family to be transported to Ciampino airfield, while avoiding the Italian police. Ciano was picked up by one car while his wife Edda and their three children were taken while walking in the park, by a different route, by another car, to a pre-assigned meeting point in the city where they were placed in a German army truck for the airport transfer. From Ciampino they were flown to Munich on board a Luftwaffe Ju 52 transport. What Ciano regarded as his escape was organised personally by Beetz's new boss Wilhelm Hottl. For Hottl and German Intelligence, the over-riding objective of the "Ciano operation" was to obtain Ciano's diaries and extensive supporting papers concerning his years at the heart of Italy's political establishment, which the German government feared might include incriminating or embarrassing information about relations between the two governments or, indeed, about the German foreign minister, Joachim von Ribbentrop (whom Ciano was known to hate).
Passage 3:Under Dutch manager Dick Advocaat, Denisov blossomed as a player, developing into an advanced midfield role behind Andrey Arshavin and Aleksandr Kerzhakov, becoming an influential member of the Zenit squad that won their first Russian Premier League title in 2007. On 3 April 2008, Denisov scored Zenit's fourth goal in their 41 first leg defeat of Bayer Leverkusen in the quarter-finals of the UEFA Cup match at the BayArena. Denisov's performances helped Zenit reach the final against Scottish side Rangers on 15 May, after defeating Bayern Munich 51 on aggregate in the semi-finals. In the final, Denisov played the full ninety minutes and opened the scoring in the 72nd minute after being played in by winger Andrei Arshavin. Zenit went on to win the match 20 and lift the UEFA Cup for the first time in their history. In the resulting UEFA Super Cup, Denisov played the full ninety again, assisting Pavel Pogrebnyak's headed goal as Zenit upset English heavyweight Manchester United 21 on 29 August 2008.
