instruction:

question:
What was Cork City formerly surrounded by?, Context: The city's charter was granted by Prince John, as Lord of Ireland, in 1185. The city was once fully walled, and some wall sections and gates remain today. For much of the Middle Ages, Cork city was an outpost of Old English culture in the midst of a predominantly hostile Gaelic countryside and cut off from the English government in the Pale around Dublin. Neighbouring Gaelic and Hiberno-Norman lords extorted "Black Rent" from the citizens to keep them from attacking the city. The present extent of the city has exceeded the medieval boundaries of the Barony of Cork City; it now takes in much of the neighbouring Barony of Cork. Together, these baronies are located between the Barony of Barrymore to the east, Muskerry East to the west and Kerrycurrihy to the south.
answer:
wall


question:
Which city did the Sea Wolves play for before Hartford?, Context: While some teams have enjoyed considerable on-field and even financial success, many teams in the history of the league have enjoyed little success either on or off of the field of play. There are a number of franchises which existed in the form of a number of largely-unrelated teams under numerous management groups until they folded (an example is the New York CityHawks whose owners transferred the team from New York to Hartford to become the New England Sea Wolves after two seasons, then after another two seasons were sold and became the Toronto Phantoms, who lasted another two seasons until folding). There are a number of reasons why these teams failed, including financially weak ownership groups, lack of deep financial support from some owners otherwise capable of providing it, lack of media exposure, and the host city's evident lack of interest in its team or the sport as a whole.
answer:
New York


question:
A turbine is the main part of a nuclear-powered ship, but what else is needed?, Context: Virtually all nuclear power plants generate electricity by heating water to provide steam that drives a turbine connected to an electrical generator. Nuclear-powered ships and submarines either use a steam turbine directly for main propulsion, with generators providing auxiliary power, or else employ turbo-electric transmission, where the steam drives a turbo generator set with propulsion provided by electric motors. A limited number of steam turbine railroad locomotives were manufactured. Some non-condensing direct-drive locomotives did meet with some success for long haul freight operations in Sweden and for express passenger work in Britain, but were not repeated. Elsewhere, notably in the U.S.A., more advanced designs with electric transmission were built experimentally, but not reproduced. It was found that steam turbines were not ideally suited to the railroad environment and these locomotives failed to oust the classic reciprocating steam unit in the way that modern diesel and electric traction has done.[citation needed]
answer:

generators
