Final answer:
The correct answer is option 1. Paul's question about returning before the ice breaks in "Wolves of Fear" is an example of foreshadowing, which is a literary device used to hint at future events in a story.
Step-by-step explanation:
In the context of the story "Wolves of Fear", when Paul asks the trapper about what would happen "if something did happen... and [they] had to go back before the ice broke", this is an example of foreshadowing. Foreshadowing is a literary device that an author uses to give an advance hint of what is to come later in the story. This narrative technique often helps to build anticipation in the audience's minds, creating tension or preparing them for a future event.
For instance, in Sophocles' play "Antigone", the character Tiresias provides a forewarning that could avert tragedy, though whether it is heeded is another matter. Similarly, Paul's question implies that there is a genuine concern or possibility of a necessary but difficult return journey, hinting at future challenges or complications in the plot.
