Task: Question Generation
Input (English):  The Maid of Sker is set at the end of the 18th century, and the story is told by Davy Llewellyn, an old fisherman. The story concerns a two-year-old girl who drifts in a boat onto a beach in Glamorganshire in the calm before a storm. The little girl calls herself Bardie. Llewellyn is tempted to keep the girl, but decides to give her up and keeps the boat for himself. He quarters the pretty child in a simple, but well-to-do, household in his neighbourhood. As she grows up he dotes upon her so far as he can. He watches anxiously over her fortunes, partly or principally because he thinks his own may be bound up with them. It is clear from the refinement of the girl's manners, and from the fineness of her clothes she was washed ashore in, that she is no common child.
Davy joins the crew of a ketch trading between Barnstaple and Porthcawl. Whilst in Devon, he encounters several characters who hold the key to solving the mystery of the maid of Sker. These include Sir Philip Bampfylde who spends most of his time looking for his two grandchildren who have mysteriously disappeared; Parson Chowne, a parson of demoniac wickedness and craft who works his will for many years in the north of Devon, defying God, man, and the law; and Captain Drake Bamfylde who is under suspicion of having made away with the children of his elder brother, and heirs to the family property. Old Davy gradually unravels the mystery and sets matters right, although many distractions delay him including an extended period at sea in which Blackmore gives a graphic account of the Battle of the Nile.
Output (English): How does Davy know Bardie is not a common child?
