The best choice that describes the difference between a monologue and a soliloquy is: In a monologue, a character gives a speech. In a soliloquy, a character believes they are alone.
To elaborate:
- A monologue is a longer speech given by one character, which can be addressed to other characters or an audience.
- A soliloquy is a specific type of monologue where a character speaks their thoughts aloud while alone on stage, revealing their inner thoughts and feelings to the audience.
