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: How many people died in the revolt in which Whitty was awarded the Military Cross? Passage 1:John Henry Hamlyn Whitty (4 February 1910 – 23 October 1944) was an Australian-born English first-class cricketer and British Army officer. Enlisting in the Queen's Own Royal West Kent Regiment in 1931, Whitty served with the regiment during the 1936–1939 Arab Revolt, during which he was awarded the Military Cross. He later served during the Second World War, during which he was wounded in action at Dunkirk. Later in the war he served in North Africa, where he was considered by Field Marshal Montgomery as the best field commander in the Eighth Army. Following service in North Africa, Whitty fought in the Italian Campaign, during which he was awarded the Distinguished Service Order, before being killed in October 1944 after stepping on a landmine. During his military career, he also played first-class cricket for the British Army cricket team.
 Passage 2:Parsons was born in Winter Haven, Florida and developed an interest in country music while attending Harvard University. He founded the International Submarine Band in 1966, but the group disbanded prior to the 1968 release of its debut album, Safe at Home. Parsons joined The Byrds in early 1968 and played a pivotal role in the making of the seminal Sweetheart of the Rodeo album. After leaving the group in late 1968, Parsons and fellow Byrd Chris Hillman formed The Flying Burrito Brothers in 1969; the band released its debut, The Gilded Palace of Sin, the same year. The album was well received but failed commercially. After a sloppy cross-country tour, the band hastily recorded Burrito Deluxe. Parsons was fired from the band before the album's release in early 1970. Emmylou Harris assisted him on vocals for his first solo record, GP, released in 1973. Although it received enthusiastic reviews, the release failed to chart. His next album, Grievous Angel, peaked at number 195 on the Billboard chart. His health deteriorated due to several years of drug abuse and he died in 1973 at the age of 26.
 Passage 3:She married comedian, songwriter and record producer John Laurence Criner (1914–1992), and recorded several songs with Johnny Otis for the G&G and Gem labels, both parts of Criner's Royal Records group. She also recorded for Miltone Records in 1947, one of her songs being an answer record to label owner Roy Milton's own "R.M. Blues". During the 1950s, she recorded a number of tracks for Aladdin Records, including in 1953 the first version of "Dial That Telephone", a comedic monologue in which she complains to a friend about the absence of her husband. She also recorded with Ike Carpenter's orchestra. In 1955 and 1956, she recorded several tracks including "Champagne Mind With A Soda Water Income" with the Squires, a vocal group featuring Don Harris and Dewey Terry (later Don and Dewey). She recorded several versions of "Dial That Telephone" over the years, including a 1959 version released on Criner's Spot record label. However, the song only became a chart success in 1965, when a new recording on the Duo Disc label reached #36 on the Billboard R&B chart. In 1968, her recording of "Harper Valley P.T.A. Gossip", a spoken elaboration of the content of Jeannie C. Riley's hit "Harper Valley PTA", reached #43 on the R&B chart.
