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: What is the birthplace of the man who commanded the  Confederate Army of Northern Virginia? Passage 1:Travelogue writer, brother of more noted Ivan, the writer of the well-known epic Smrt Smail-age Čengića. He attended a German school in his native town, where he was trained to become a blacksmith. Often he indulged into travels (Montenegro, Serbia), and exceptionally in a few occasions to Bosnia. In 1841 he was back to Novi, practicing his craft and agriculture, but also engaging in literature and cultural issues in general. In 1847 he ended up in Vienna, in 1848 again in Bosnia (in Sarajevo, at the court of Fazli-paša Šerifija). At the end of 1848, in a letter addressed to his brothers he says: "I don't know when I shall return home, for I have been, I'm afraid, created for this country. Turks are very fond of me for my prudence, they say, and rayah grows ever more trust in me, and therefrom there is no other outcome but mitre on the head or a stake in the arse". After Sarajevo, Matija went to Istanbul (though the exact dates cannot be ascertained), and according to some legends even further, to Suez and the Egypt. In 1852 Matija was back to Novi, where he settled until growing ill in 1879. He lived a secluded life until the symptoms of mind degeneration have started to show, finally dying in the sanatorium of a well-known psychiatrist Richard von Krafft-Ebing, near Graz, on April 17, 1881.
 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.
 Passage 3:Great Australian Bight Marine National Park is a marine protected area in the Australian state of South Australia located west of the state capital of Adelaide. The national park was proclaimed under the National Parks and Wildlife Act 1972 (SA) by the South Australian Government on 26 September 1996 principally to protect the calving waters of the Southern right whale and the Australian sea lion populations. It consists of two sections occupying the ocean immediately adjoining the coastline up to a distance of and extending from the Western Australia border in the west to a locality known as the Tchalingaby Sandhills in the east. The gap between the two sections is also a protected area known as the Great Australian Bight Marine Park Whale Sanctuary which was proclaimed on 22 June 1995 under the Fisheries Act 1982 (SA). The national park is also part of the group of marine protected areas which are located together in waters within Australian and South Australian jurisdictions within the Great Australian Bight and which is collectively known as the Great Australian Bight Marine Park. Since late 2012, the national park and the whale sanctuary have also been within the boundaries of the Far West Coast Marine Park.
