One 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.

Now, solve this: Question: How long had Bournemouth & Boscombe Athletic been a club when Coughlin signed with them? Passage 1:Forrest was born in Perth as one of five children born to Amy Eliza (née Barrett-Lennard) and Alexander Forrest. On his mother's side, he was a descendant of the Barrett-Lennard baronets and the Barons Dacre. His father was an explorer and surveyor who later served as Mayor of Perth, and represented the seat of West Kimberley in the Western Australian Legislative Assembly. His uncles, David and John Forrest, were also politicians, with the latter serving as the first Premier of Western Australia. Growing up, Forrest attended The High School (later Hale School) on St Georges Terrace in the centre of Perth. At school, he was a noted sportsman, and later served as a prefect of the school. Forrest was the bowman for the crew that won the first Head of the River race in 1899 and kept wicket for the school's cricket team. He also played a number of games for the school's football team, and captained the side to victories against Christian Brothers' College and Scotch College.
 Passage 2:Coughlin began his career at Shiney Row St Oswald's, before moving on to Durham City. In 1957, Coughlin signed for Football League club Barnsley.

In March 1963, Coughlin moved back to the Football League, signing for Bournemouth & Boscombe Athletic. Coughlin made 88 appearances for the club, scoring 40 times. In August 1966, Coughlin signed for Swansea Town, in a deal that saw Ken Pound go the other way to Bournemouth.

Coughlin scored two goals in 13 appearances for Exeter, returning to Non-League football with Chelmsford City ahead of the 1968–69 season.

He then retired shortly afterwards due to brake failure. Gutiérrez finished 14th at the Chinese Grand Prix, passing Nico Hülkenberg in the closing laps. At the Russian Grand Prix, Gutiérrez made contact with Hülkenberg, forcing him to pit for a new front wing. At the Spanish Grand Prix, Gutiérrez was in 8th until he was passed by Felipe Massa, Jenson Button and Daniil Kvyat in the closing laps, dropping him to 11th. Gutiérrez finished 11th at the Monaco Grand Prix, but crossed the line 12th, after being pushed out the way by Valtteri Bottas on the final lap. Bottas was given a five-second time penalty, promoting Gutiérrez back to 11th. At the European Grand Prix, Gutiérrez made contact with Hülkenberg on the first lap, damaging his front wing. At the Austrian Grand Prix, Gutiérrez finished 11th after Sergio Pérez had a brake failure and crashed out on the final lap. On the final lap, Lewis Hamilton and Nico Rosberg made contact. Rosberg lost his front wing and Pascal Wehrlein and Gutiérrez passed him. Gutiérrez attempted to find a way past Wehrlein for 10th, but Wehrlein just beat him to the chequered flag.
