Final answer:
The claim that the Furies convince Electra that Orestes is a murderer and hence she fears him is false. Electra typically supports Orestes' quest for vengeance in Greek tragedies.
Step-by-step explanation:
The statement that the Furies convince Electra that Orestes is a murderer, making her frightened of him, is false. In classical Greek tragedy, the Furies, also known as the Erinyes, were primarily associated with the persecution of crimes, particularly those against family. However, in the given context regarding the characters Electra and Orestes, this scenario does not align with the typical narrative surrounding these characters in most ancient Greek plays. For example, in Aeschylus' Oresteia trilogy, Electra is aware of Orestes' actions, which are in part motivated by the command of the god Apollo, to avenge the murder of their father, Agamemnon, by killing their mother, Clytemnestra, and her lover, Aegisthus.
