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 was the occupation of Telfer's paternal grandmother? Passage 1:Peter Jackson and partner/co-writer Fran Walsh conceived the idea for The Frighteners in 1992, during the script-writing phase of Heavenly Creatures. Together, they wrote a three-page film treatment and sent it to their talent agent in Hollywood. Robert Zemeckis viewed their treatment with the intention of directing The Frighteners as a spin-off film of the television series, Tales from the Crypt (which he helped produce). Zemeckis hired Jackson and Walsh to turn their treatment into a full-length screenplay in January 1993. The husband and wife duo completed their first draft for The Frighteners in early-January 1994. Zemeckis was so impressed with their script, he decided The Frighteners would work better directed by Jackson, executive produced by Zemeckis and funded/distributed by Universal Pictures. Universal green-lighted the film to commence pre-production on a $26 million budget in April 1994. The studio also granted Jackson and Zemeckis total artistic control and the right of final cut privilege.
 Passage 2:The son of Margaret Mellis and Adrian Stokes, he was born in St Ives and studied at the Slade School of Fine Art. He pursued postgraduate studies at the Brooklyn Museum Art School after being awarded a Beckmann Fellowship. He taught at Reading Art School and the Bath Academy in Corsham and exhibited his paintings in London, including a show at the Serpentine Gallery. In 1971, Stokes founded publishing firm Weproductions, which produced artist's books; from 1974, he operated in partnership with Helen Douglas. In 2002, Stokes moved to East Anglia to care for his mother. He redirected his focus to sculpture, which he exhibited at the Kettle's Yard open house in 2008 and at shows in various galleries.
 Passage 3:For the 2009 season the Phillies wore black, circular "HK" patches over their hearts in memory of broadcaster Harry Kalas, who died April 13, 2009, just before he was to broadcast a Phillies game in Washington, D.C. From Opening Day through July 26, 2009, the Phillies wore 2008 World Champions patches on the right sleeve of their home uniforms to celebrate their World Series victory the season prior. After the death of Hall of Fame pitcher Robin Roberts on May 6, 2010, the Phillies wore a black patch with a white "36" on the sleeves of their jerseys in memory of Roberts for the remainder of the 2010 season. Number 36 had been retired previously by the team in 1962 to honor Roberts. For the 2011 season, the Phillies wore a black circular patch with a "B" in honor of minority owners Alexander and John Buck, who died in late 2010. For the 2014 season, the Phillies wore a black circular patch with initials “CB” in honor of former owner Claire Betz, who died during the offseason. For the 2015 season, the Phillies wore a black circular patch with a white "SLB" in memory of minority owner Sara L. Buck, who died on August 23, 2014. For the 2017 season, the Phillies wore a black circular patch on their sleeves featuring the "baseball stitched" center swirl "P" used from 1970 to 1991 inside the white silhouette of a capital "D" in memory of former manager Dallas Green, who led the franchise to its first World Series championship and died on March 22, 2017. Following the death of former chairman, minority-owner, and president David Montgomery on May 8, 2019, the Phillies added a black circular patch with white "DPM" letters in memory of Montgomery for the remainder of the 2019 season.
