Final answer:
García Márquez foreshadows Santiago's death with a graphic image that makes it appear as if he is already dead.
Step-by-step explanation:
García Márquez foreshadows Santiago's death with a graphic image in which he appears already dead. This use of imagery creates a sense of foreboding and inevitability. One example of this is seen in the description of a row of French soldiers aiming their guns at Santiago, with a pile of dead bodies at his feet, streaming blood. This image suggests that Santiago's death is imminent and unavoidable.
