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.

Part 3. Exercise
Question: How long is the fault that lies to the east of Ice Mountain? Passage 1:Nothing is known of Justin's origins or early life. He appears for the first time in 528, when along with Narses he was sent to Italy with 7,000 men as reinforcements for Belisarius, who had just successfully survived siege of Rome by the Ostrogoths. At the time, he held the position of magister militum per Illyricum, a post he may have been appointed to already in 536, after the death of general Mundus. In the dissension that broke out in the Byzantine army between Belisarius and Narses, Justin sided with the latter, and accompanied him to the relief of the Gothic siege of Ariminum, defended by the general John. After the successful outcome of the operation, along with John, Justin proceeded to occupy the region of Aemilia against little Gothic resistance during the winter of 538/539. The rift in the imperial army had by this time deepened to the point that Justin and John outright refused to obey orders from Belisarius to march to the aid of the city of Mediolanum, which was being besieged by the Goths with their Frankish allies, instead waiting for relevant orders from Narses. The delay proved fatal, and the great city was captured and razed by the Franko-Gothic army.
Passage 2:Ice Mountain is an arc-shaped forested ridge of the Allegheny Mountains, part of the Ridge-and-valley Appalachians. It is above mean sea level at its summit. Ice Mountain is a large mass of Devonian Oriskany (Ridgeley) sandstone and Marcellus shale with numerous bare rock slopes and vertical cliffs. Ice Mountain lies on the west side of the Timber Mountain anticline and to the west of North Mountain fault, which places it on the Martinsburg allochthonous sheet. Ice Mountain is situated along North River and is known for the several hundred yards of ice that form at its base all year long. At its southern end overlooking the community of North River Mills is located Raven Rocks, a set of stone chimney outcrops. Raven Rocks is in height above mean sea level with vertical cliffs measuring nearly in height. Raven Rocks were named because of the presence of ravens during pioneer days. The present Raven Rocks is the remaining vestige of a once towering cliff that overlooked the North River. Geologically, Ice Mountain is a northern extension of North River Mountain.
Passage 3:York started his career with Handsworth Royal, Birchfield Rangers and the Royal Air Force, and also guested for Chelsea during World War I. In March 1915 he joined Aston Villa as an amateur, signing professional forms in August 1919. He scored one goal in 17 games in 191920, but did not feature in the 1920 FA Cup Final, which ended in a 10 victory over Huddersfield Town at Stamford Bridge. He appeared just 11 times in 192021, before going on to make 47 appearances in the 192122 campaign, as the "Villans" finished fifth in the First Division. He scored nine goals in 37 games in 192223 and five goals in 43 games in 192324. He also appeared at Wembley in the 1924 FA Cup Final, in a 20 defeat to Newcastle United. He scored seven goals in 34 matches in 192425, before hitting 20 goals in 44 appearances in 192526. He bagged 13 goals in 43 games in 192627, before being limited to just four goals in 30 appearances in 192728. He rediscovered his scoring form with 18 strikes in 48 matches in 192829, before hitting seven goals in 32 games in 192930. However he played just four times in the 193031 campaign, as Villa finished second in the league with an English record of 128 top-flight league goals scored.
