Task: Question Generation
Input (English): Many of London's pubs are known to have been used by famous people, but in some cases, such as the association between Samuel Johnson and Ye Olde Cheshire Cheese, this is speculative, based on little more than the fact that the person is known to have lived nearby. However, Charles Dickens is known to have visited the Cheshire Cheese, the Prospect of Whitby, Ye Olde Cock Tavern and many others. Samuel Pepys is also associated with the Prospect of Whitby and the Cock Tavern.
Output (English): What writer was known to visit both the Cheshire Cheese and the Prospect of Whitby?
