Final answer:
Foreshadowing is a technique where hints about future events are given in advance; in 'Antigone,' Tiresias warns Creon of future troubles, which is a classic example of this device. Lines 461-464 are expected to contain similar clues that contribute to the narrative's tension.
Step-by-step explanation:
Foreshadowing is a literary device in which an author provides hints or clues about events that will happen later in the story. For example, in the play Antigone, the character Tiresias uses ominous language when he warns King Creon that dire consequences will befall his family unless he changes his ways. This foreshadowing builds suspense and prepares the audience for the unfolding drama. Lines 461-464 likely contain textual evidence that hints at future plot points, serving to alert the reader or viewer that significant developments are on the horizon; specific details in these lines would probably echo the theme of Tiresias's prophecy, indicating the seriousness of Creon's situation and the potential for tragedy.
