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: How old was the Preston manager when he began managing Stevenage? Passage 1:Joe Camilleri was born the third of ten children in Malta in 1948. The family migrated to Australia when he was two. Camilleri grew up in Port Melbourne and listened to rock music on the radio. His mother called him Zep and he became known as Jo Zep. Camilleri began his music career in 1964 when literally thrown onstage to sing with The Drollies. He played blues and R&B in the mid-1960s with The King Bees, and was then a member of Adderley Smith Blues Band. In 1968, lead singer for the band, Broderick Smith had been conscripted for National Service during the Vietnam War. Camilleri lasted a year with Adderley Smith, and enjoyed working with the band including guitarist Kerryn Tolhurst (later in The Dingoes with Smith). According to Australian music journalist Ed Nimmervoll, Camilleri was sacked for sounding too much like Mick Jagger and upstaging other band members. After Adderley Smith, Camilleri was a member of various bands, including The Pelaco Brothers during 1974–1975.
 Passage 2:King experienced full-time professional football for the first time when he signed for League One side Preston North End on a one-year deal in July 2012. Preston manager Graham Westley had previously scouted King several times whilst he managed Stevenage, but felt he was too similar a player to Michael Bostwick, and therefore no move materialised at the time. King made his debut for Preston in a 2–0 victory over Huddersfield Town in the League Cup on 13 August 2012, a game in which he scored the opening goal of the match courtesy of a header. King adjusted well to playing in the Football League for the first time in his career, scoring three times in four games in the opening months of the season; two coming in league victories over Hartlepool United and Doncaster Rovers respectively, and the other in a 3–1 League Cup loss to Middlesbrough at Deepdale. He added his fifth goal of the season when his deflected shot found in the net in Preston's 4–1 win against Stevenage on 10 November 2012. King was on the scoresheet once again a month later, scoring with a powerful shot in a 3–3 Football League Trophy penalties win over Bury on 18 December 2012. King remained a regular feature under new manager Simon Grayson, and scored his first goal under Grayson's management in Preston's comfortable 3–0 victory against Scunthorpe United on 6 April 2013 when he headed in Jeffrey Monakana's cross to seal the win. He played 47 times during the 2012–13 campaign, scoring seven times, as Preston finished the season in 14th place.
 Passage 3:While telling Bart and Lisa about 1990, Homer says, "Tracey Ullman was entertaining America with [...] crudely drawn filler material." This is a reference to The Simpsonss debut as "bumpers" airing before and after commercials on The Tracey Ullman Show. The song "Those Were the Days" parodies the opening credits of the television show All in the Family. One of the people who run over the saxophone is a man on a tricycle, who promptly falls over. This is a reference to the show Rowan & Martin's Laugh-In. At the beginning of the flashback, the song "Don't Worry, Be Happy" by Bobby McFerrin can be heard. In the flashback, Dr. Hibbert fashioned his hair and attire like Mr. T in The A-Team. Homer can be seen watching Twin Peaks and The Giant is then shown waltzing with the White Horse. In King Toot's music store, when Homer buys Lisa her first saxophone, there is a guitar in the background that is similar to Eddie Van Halen's "Frankenstrat" guitar. The photo beside Kent Brockman on the news has him modeled after the Coppertone Girl. At the end of the episode, Lisa performs a brief, cruder rendition of the hook of "Baker Street" by Gerry Rafferty on her new saxophone before the music segues into the original song.
