Example Input: Question: When was the museum ship in Halifax first opened? Passage:The city is overlooked by a large museum and national historic site, the Halifax Citadel not far from the province's Natural History Museum. The Maritime Museum of the Atlantic, the oldest and largest maritime museum in Canada explores the cultural and technology of the province's seafaring heritage. Moored beside the Maritime Museum is the museum ship HMCS Sackville, Canada's naval memorial. The city's rich naval history is also presented at the Maritime Command Museum in the city's North End. The Pier 21 Immigration Museum located a former ocean liner immigration shed features Canada's immigration history. Across the harbour, the Dartmouth Heritage Museum preserves the history of the Dartmouth side of the Harbour. The Black Cultural Centre for Nova Scotia in Cherrybrook celebrates the history and culture of African Nova Scotians. A variety of community museums across the municipality showcase community history such as the Fultz House Museum in Sackville and the Musquodoboit Railway Museum in Musquodoboit Harbour.

Example Input: Question: Was the coach that Culverhouse hired younger than the person he replaced? Passage:Former Atlanta Falcons coach Leeman Bennett was named by owner Hugh Culverhouse as the replacement for retired head coach John McKay. Other candidates interviewed included Buccaneer defensive coordinator Wayne Fontes, Seattle Seahawks defensive coordinator Tom Catlin, former Michigan Panthers head coach Jim Stanley, former New England Patriots head coach Ron Meyer, Washington Redskins quarterback coach Jerry Rhome, former Pittsburgh Steelers defensive coordinator Bud Carson, and former Florida Gators coach Charley Pell. Bennett was an unexpected choice, as Fontes had long been considered to be the leading candidate and had the near-unanimous support of the players and existing staff. Culverhouse almost gave Fontes the job without conducting an interview process, before having second thoughts and soliciting recommendations from McKay, Tex Schramm, and Dan Rooney. Described as "heartbroken", Fontes learned while attending a scouting combine in Arizona that he had been passed over for the job. Bennett indicated that nobody who had been a candidate for the head coaching job would be hired as an assistant, ending speculation that he might retain Fontes or bring in his former assistant Jim Stanley. Fontes eventually accepted the defensive coordinator position with the Detroit Lions.

Example Input: Question: What year was the Poole Logboat found by archaeologists? Passage:The Poole Harbour area has been inhabited for at least 2,500 years. During the Iron Age, Celtic people known as the Durotriges lived in Dorset, particularly around Wareham, five miles (8 km) to the west. In the 3rd century BC, these Celtic people moved from hilltop settlements, such as Maiden Castle and Badbury Rings on the chalk downs to the north, to the lower vales and heathland around the River Frome and Poole Harbour. This marshy area may have lent its name to the Durotriges, which means "water dwellers". The Durotriges engaged in cross-channel trading at Poole with the Veneti, a seafaring tribe from Brittany. The earliest significant archaeological find in the harbour is the Poole Logboat, a boat made from a single oak tree and dating to 295 BC. During that time, the harbour was shallower than it is today and any settlement would now be under water.
