Part 2. 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.

Part 3. Exercise
Question: In which city was the painting before being moved to its final home? Passage 1:He was born in Edinburgh on 14 March 1771, the only son of Henry Dundas, 1st Viscount Melville, and his first wife, the former Elizabeth Rannie (1751–1843). Educated at the Royal High School, Edinburgh, he went in 1786 with his tutor John Bruce on a continental tour and enrolled at Göttingen University. He studied afterwards at the University of Edinburgh and at Emmanuel College, Cambridge, and was admitted at Lincoln's Inn in 1788. After a successful attempt at law he became his father's private secretary from 1794, though he was brought in as MP for Hastings in 1794, and then Rye in 1796. The same year, on 29 August, he married an heiress, Anne Saunders (died 10 Sept 1841), and took her name beside his own. They had four sons and two daughters; their eldest son, Henry Dundas, later third Viscount Melville, became an army officer while their second son, Richard Saunders Dundas, became First Naval Lord.
 Passage 2:The Very Best of TLC: Crazy Sexy Hits material is taken from four of their studio albums: Ooooooohhh... On the TLC Tip (1992), CrazySexyCool (1994), FanMail (1999), and 3D (2002), and Now & Forever: The Hits (2003), which were all recorded from 1991 to 2003. Their 1993 cover of The Time's "Get It Up" for the soundtrack to Poetic Justice does not appear on any of their studio albums, but still appears on the compilation along with the trio's most successful singles in the United Kingdom. These include "No Scrubs", which placed at number three on the UK Singles Chart and was awarded a platinum certification from the British Phonographic Industry (BPI); "Waterfalls", which peaked at number four on the UK Singles Chart and also achieved platinum status; "Unpretty", a silver-certificated single which peaked at number six on the UK Singles Chart, and "Creep", which also peaked at number six on the UK Singles Chart after being reissued across the UK and Europe. It did not, however, include "Dear Lie", a moderately received UK single which was certified silver. Instead, the non-charting songs "Come Get Some", "Damaged" and "Get It Up" were included in the final track listing, with "Whoop De Woo" (a non-album track) and "In Your Arms Tonight" (from 3D) the only two non-single tracks that appeared the compilation.
 Passage 3:By 1627 the painting belonged to William Herbert, 3rd Earl of Pembroke (1580-1630), and was at Wilton House in Wiltshire. Either the 3rd or 4th earl presented it to King Charles I of England. After the English Civil War it was sold in one of the sales of the Royal Collection at Somerset House in London on 19 December 1651. Soon after it was in France. The painting was later a highlight of the Pierre Crozat collection which was acquired through Diderot's mediation by Catherine II of Russia in 1772. For a century and a half, the panel hung in the Imperial Hermitage Museum. It was one of the most popular paintings in the entire collection of the Tsars. In March 1931 it was part of the Soviet sale of Hermitage paintings, and bought by Andrew Mellon, as part of his founding donation to the National Gallery of Art in Washington D.C. This and other foundational artworks, including paintings by Jan van Eyck, Sandro Botticelli, and Titian, helped place the National Gallery among the most significant collections of Renaissance art.
