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: Is Pravisdomini located in Austria? Passage 1:In 1658 Hungerford was elected Member of Parliament for Chippenham in the Third Protectorate Parliament. He was elected MP for Chippenham in 1660 for the Convention Parliament. He was made a Knight of the Bath at the coronation of King Charles II on 23 April 1661. In 1661 he was elected for Chippenham again in the Cavalier Parliament but the election was declared void. He was then re-elected in the by-election later in 1661 and also in the two elections in 1679. In January 1680 he presented a petition for the summoning of a parliament, and his avowed opposition to the court party of King Charles II led to his removal as Lord Lieutenant of his county in May 1681. He settled in Spring Gardens, Whitehall, in 1681 and was elected MP for Chippenham again in the Oxford Parliament of 1681. He was implicated in the 1683 Rye House Plot and his home at Farleigh Castle was searched for arms. He was elected MP for New Shoreham in 1685, 1688, and 1690, and for Steyning in 1695, 1698, 1700, and 1702.
 Passage 2:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Félix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Bašić in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomáš Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.
 Passage 3:This extended training period meant that he had accumulated 138 flying hours in his pilot's logbook before he finally joined No. 66 Squadron RFC in Italy on 10 March 1918. He was assigned to "C" Flight, flying a Sopwith Camel single seat fighter, and became the preferred wingman of fellow Canadian ace Billy Barker. Birks' first aerial victory came on 18 March, when he destroyed a Rumpler reconnaissance aircraft over Pravisdomini, killing an Austro-Hungarian pilot named Shneeberger. Six days later, he set another reconnaissance aircraft on fire, killing the crew of Poelzi and Suski. His third victory would not come until 2 May, when he wounded Leutnant K. Kosiuski and drove him into a crash landing that destroyed his Albatros D.V. Two days later, Birks shot down and killed ace Oberleutnant Karl Patzelt, as well as F. Frisch. In addition to killing both Austro-Hungarian pilots, he destroyed both their Albatros D.Vs; they were credited as "captured" because they fell within Italian lines. The new ace shot down another D.V in flames a week later, on 11 May. He destroyed two Berg fighters in five minutes on a morning patrol on 19 May. The following day, he destroyed another. On 24 May, while flying with Barker, Birks was credited with shooting down Hungarian ace József Kiss of Flik 55J; Birks thus became a double ace. On 9 June Birks set another Albatros D.V on fire in mid-air. On the 21st, he capped his list of triumphs by destroying another D.V over Motta. Most unusually for a British pilot, he had no "soft" victories, such as "driven down out of control".
