Task: Question Generation
Input (English): Pub names are used to identify and differentiate each pub. Modern names are sometimes a marketing ploy or attempt to create "brand awareness", frequently using a comic theme thought to be memorable, Slug and Lettuce for a pub chain being an example. Interesting origins are not confined to old or traditional names, however. Names and their origins can be broken up into a relatively small number of categories.
Output (English): What is an example of a memorable name for a pub chain?
