Example input: 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.

Q: Question: Which of Microsoft's gaming systems for which the Forza series was developed has sold the most units? Passage 1:The show features an ensemble cast. For the first season, nine actors received the star billing: Connie Britton as Rayna Jaymes, a 40-year-old country music superstar singer whose stardom is beginning to fade; Hayden Panettiere as Juliette Barnes, a bubblegum country pop singer and former teen star sensation who is determined to replace Rayna as the top superstar of country music; Clare Bowen as Scarlett O'Connor, a poet and songwriter Deacon's niece, and musician partner with Gunnar who works at the Bluebird Cafe which is where she is first noticed and performs; Eric Close as Theodore "Teddy" Conrad, Rayna's husband who, after a business failure, is now living on his wife's income. He runs for mayor with help from his father-in-law and wins election, later divorcing Rayna; Charles Esten as Deacon Claybourne, songwriter, lead guitar player, Rayna's former lover and biological father of her oldest child.; Jonathan Jackson as Avery Barkley, an aspiring musician with a bad-boy streak. He and Scarlett are in a relationship when the series begins, but soon separate; Sam Palladio as Gunnar Scott, a kind-hearted aspiring musician who dates Scarlett in season one, and dates Zoey in season two; Robert Wisdom as Coleman Carlisle, a one-time mayoral candidate, and later Deputy Mayor, close friend of Rayna, and serves as Deacon's sobriety sponsor; and Powers Boothe as Lamar Wyatt, Rayna's father and a wealthy, powerful and controlling patriarch and local politician who disapproves of his daughter's career as a country singer.
 Passage 2:Klammer first showed signs of promise in the second half of the 1973 World Cup season, finishing second in the St. Anton downhill behind Bernhard Russi of Switzerland, the reigning Olympic and World Cup downhill champion. Klammer, age 19, followed this up with a third at St. Moritz and a third in the giant slalom at Mont Sainte-Anne (the only time he finished on the podium in a World Cup Giant Slalom in his career). The following season he finished second in the downhill standings behind Roland Collombin of Switzerland, his nemesis that season. After beating Collombin and Russi at Schladming in December 1973 under terrible conditions, Collombin bested him at Garmisch, Avoriaz, and Wengen. In December 1974, Collombin fell at Val-d'Isère, as he had the previous year. This time Collombin broke his back in a training run, unfortunately ending his promising career. Klammer won that race and every other downhill that 1975 season, except Megève, where one of his skis came off; without this incident, he would have won the overall World Cup title in March 1975, due to a good slalom result two days before at Chamonix, which would have granted him at least a third place (15 points) for the AK-combined of slalom Chamonix / downhill Megève. In the Olympic test event at Patscherkofel at Innsbruck in January 1975, Klammer had defeated defending Olympic champion Bernhard Russi of Switzerland, the runner-up, by nearly a half-second.
