Task: Question Generation
Input (English): The number of pubs in the UK has declined year on year, at least since 1982. Various reasons are put forward for this, such as the failure of some establishments to keep up with customer requirements. Others claim the smoking ban of 2007, intense competition from gastro-pubs, the availability of cheap alcohol in supermarkets or the general economic climate are either to blame, or are factors in the decline. Changes in demographics may be an additional factor.
Output (English): When was a smoking ban passed in the United Kingdom?
