In the passage from "The Tragedy of Julius Caesar," the following items can be considered symbols:
- Blood - Often symbolizes violence, death, or betrayal.
- Ghosts - Typically symbolize the past, unresolved issues, or foreboding.
- Lioness - Could symbolize power, strength, or a wild, untamed force.
- Streets - Might symbolize the public sphere or the arena of conflict and consequence.
While Caesar is a significant character and figure within the play, he does not function as a symbol in the same way as the other items listed. Thus, you would check all options except Caesar.
