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 city was the Shalem center located? Passage 1:Emmanuel Navon was born in Paris, France, as Emmanuel Mréjen. As a child, he attended the international bilingual school (French/English). He graduated from Sciences-Po, majoring in Public Administration. During his studies at Sciences-Po, he interned at the French Foreign Ministry and at the French Ministry of Finance. In 1993, he immigrated to Israel and subsequently hebraized his last name to Navon. In Israel, Navon enrolled in the Israel Defense Forces and pursued his graduate studies at the Hebrew University of Jerusalem, earning a master's degree and a Ph.D. in international relations. During his studies at the Hebrew University, he consulted to the Israeli Foreign Ministry on the reform of the United Nations and joined the Shalem Center as a doctoral fellow.
 Passage 2:During the Morean War, monastery was in peril twice. Apparently, during the first plunder of Cetinje, after the Battle of Vrtijeljka, the forces of Süleyman Bushati did not gravely damage the monastery. Their idea was to pacify Montenegrins, and prevent them from aiding Venetian war effort. On the other hand, his army comprised a considerable amount of forcibly mobilised Christians, and he was afraid of mutiny. The popular tale has it that expeditionary force did start to rob the monastery, however, as one of the soldiers was trying to take down a cross from the top of the roof, he was struck by lightning, which was immediately perceived as Gods sign. In 1689, the Venetians were invited to take control of Cetinje. As they arrived, they quickly fortified themselves in the monastery and in the nearby former court of Crnojević. It thus served as a garrison for three years, when Cetinje was attacked again by Suleyman on 25 September 1692. Instead of fighting, Venetians entered negotiations, and reached an agreement to abandon the monastery under honorable terms. However, they mined a monastery with a time bomb, which set of in the evening hours, right after Venetians retreated and as the Ottomans were victoriously entering the monastery, killing many of them in the process. This resulted in seat of Metropolitanate being moved to Dobrska Ćelija monastery for some time. Vladika Danilo reestablished it, in 1701 or 1704, across the site of the first location, atop the remains of the court with stone from the old one, and added a tablet with the coat of arms of the Crnojević family, and a dedication to Ivan Crnojević. Before 1714, it was burnt, and then it was reconstructed yet again around 1743 by Metropolitan Sava Petrović Njegoš. It was the center of spiritual, cultural and political life of the Prince-Bishopric of Montenegro. Its importance is clearly emphasised in Prince-Bishop Vasilije's exaggerated claim, written in his "History of Montenegro", that ... before its destruction, Cetinje Monastery was among the most beautiful monasteries in Europe. The last time monastery was devastated was in 1785, when Mahmud Pasha Bushati sacked Cetinje. Ultimately defeated in the Battle of Krusi, his severed head is since then kept as a relic in the monastery. It has been built on several times, the current appearance dates to 1927. The original site of the monastery, known as Ćipur (after Greek word Κήπος - Garden) was used in 1886 by Prince Nicholas of Montenegro for his Court church. The position of the newly built church follows the lineup of the original one from inside the monastery complex. Today its ruin along with couple of pillars can be seen.
 Passage 3:Other programming on WKBF included a late-night weekend horror movie showcase hosted by Ron Sweed, whose on-air character was named The Ghoul. The Ghoul character was essentially a beatnik vampire, outfitted in a fright wig, goatee, lab coat, and a pair of sunglasses with one lens missing. It was patterned after the Ghoulardi character that was created by Ernie Anderson (with his permission), who was later to become the voice of the ABC network in the 1970s. While Anderson had no interest in doing so, he granted Sweed permission to don the costume. As WJW owned the rights to the name "Ghoulardi", the younger performer adopted the name "The Ghoul." Although WKBF has long since passed into broadcasting history, Sweed continued to make personal appearances on a fee-for-service basis in this guise until very late in life. WKBF also featured sports programming such as game telecasts from the World Football League and Cincinnati Royals NBA basketball, and harness racing.
