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: How many tracks were on Nic Jones' 1977 album? Passage 1:In 1996, Toyota Motor Sports funded the development of an experimental Le Mans Prototype, which was officially known as the TOM'S Toyota LMP. As Toyota were primarily focusing on their Championship Auto Racing Teams (CART) engine, which first ran that year, the LMP project was run on a tight budget of approximately $500,000. Due to this tight budget, the car, christened the "Lumpy", reused Toyota's 3S-GT engine in the 88C Group C specification, which was a 2.1-litre turbocharged straight-four engine, producing ; this engine was coupled to an Xtrac gearbox from a Peugeot Group C car. The chassis tub was designed to be simple but strong, and the bodywork was also simple; the tight budget meant that the LMP never saw a wind tunnel. The bodywork was designed to minimize lift over the upper body of the car, and had much simpler brake cooling than on most Le Mans Prototypes; the radiator ducts were used, via a scoop, to cool the brakes. After the LMP was completed, Tom Kristensen tested it on at least one occasion, whilst project director Andy Thorby recalled it being tested a total of three times; he stated that the car was very reliable, had lower fuel consumption than the 88C Group C car had (with the same engine), and that it also appeared to be quick. Following the completion of the tests, the car was dispatched to Toyota Team Europe's Cologne workshop, stored under a tarpaulin and eventually destroyed. Toyota would return to sportscar racing in 1998, with the André de Cortanze-designed Toyota GT-One.
 Passage 2:Nic Jones recorded his version of the song as Annachie Gordon on his 1977 album The Noah's Ark Trap (1977). Mary Black included it using the same name on the album Mary Black. Loreena McKennitt recorded it on Parallel Dreams (1989). Other versions include June Tabor's on Always (2005), Sharon Shannon's on Libertango (2004), John Wesley Harding's on Trad Arr Jones (1999) and Oliver Schroer's instrumental version on Celtic Devotion (1999). Sinéad O'Connor also recorded a version on the Sharon Shannon Collection released in 2005, and Gabrielle Angelique recorded the song on her album Dance with the Stars (2006). The Unthanks 2009 album Here's the Tender Coming also contains a version. The earliest professional recording was by Berzilla Wallin on Old Love Songs and Ballads from the Big Laurel, North Carolina (1964).
