Ethos is a Greek word that means there is an implicit or explicit set of beliefs, actions, morals or ideologies that must be followed in the actions of a group or nation. This can be seen for example here: ...towards my country, and of an act of disloyalty toward the majesty of heaven...

This is the main idea implied in this text. Correct.

Kairos is a way of appealing to aptness, properness of an action to a given situation. Even though a precise behavior is implied for the situation in the text this is not primarily used. Incorrect

A metaphor is a word or sentence used with an object that cannot literally accomplish the action given, a comparison that is implicit, expressing something hidden under the words given. This doesn't happen in this text. Incorrect

A personification happens when you assign human properties to an animal or object. in this case, there are no objects o animals. Incorrect
