Task: Question Generation
Input (English): Built in 1815, Union Street was at the heart of Plymouth's historical culture. It became known as the servicemen's playground, as it was where sailors from the Royal Navy would seek entertainment of all kinds. During the 1930s, there were 30 pubs and it attracted such performers as Charlie Chaplin to the New Palace Theatre. It is now the late-night hub of Plymouth's entertainment strip, but has a reputation for trouble at closing hours.
Output (English): How many pubs existed on Union Street in the 1930s?
