where are the following words.. you cant just ask a question and expect people to know the choices.

a foil character shows contrast with the qualities of another character. to emphasize the traits of the other character is the main objective. cassius is a foil to brutus, and brutus is a foil to antony. both cassius and antony conspire to kill caesar, but cassius is more prone to treachery than brutus is. thus, easily gives in to his evil ambition. brutus is a foil to antony because brutus’s honesty and simplicity are in clear contrast to antony’s qualities of deception and over-ambition.
