Answer:
I would say that Brutus' inner struggle with assassinating Caesar is not an example of external conflict, because it is an internal conflict.
Step-by-step explanation:
External conflicts happen when the character has a conflict with something outside of himself. Often these conflicts are versus another character, nature, or society. If something is not an external conflict, it is an internal conflict. An internal conflict is a problem the character has with himself. The struggle Brutus has with assassinating Caesar is an internal conflict and therefore not an example of external conflict.
