Final answer:
The inference from page 14 suggests that Jack and The Stranger may be involved in activities associated with the eerie and dangerous setting of a graveyard, implying a potentially sinister plot development.
Step-by-step explanation:
The inference about Jack and The Stranger that is best supported by page 14 in the book might relate to the setting of a graveyard and its implications for the plot and characters. Graveyards typically evoke a sense of eeriness and are associated with death, which could suggest Jack and The Stranger may be involved in a context that is sinister or surrounded by an air of danger and mystery. Given the context from the provided text, it could be inferred that the graveyard is a place where underhanded activities occur, and Jack and The Stranger might be waiting or lurking for some purpose that ties into the greater narrative of the story.
