Task: Question Answering
Input (English): passage: London (/ˈlʌndən/ ( listen) LUN-dən) is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km) medieval boundaries. Since at least the 19th century, ``London'' has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent and Hertfordshire, which today largely makes up Greater London, a region governed by the Mayor of London and the London Assembly.
