Final answer:
Shakespeare uses ill omens to foreshadow ominous events, building suspense in this scene.
Step-by-step explanation:
Shakespeare uses ill omens to foreshadow ominous events, building suspense in this scene. The augurers, who are skilled interpreters of omens, deliver a concerning message to Caesar's servant. They inform the servant that they could not find a heart within the animal sacrificed and advise Caesar not to go outside on that day. This creates a sense of foreboding and tension, as it suggests that something bad may happen to Caesar if he ignores the warning.
