Final answer:
Rhea displays anger when she replaces Zeus's body with a stone to protect their youngest child from being devoured.
Step-by-step explanation:
Rhea displays the emotion of anger when she replaces Zeus's body with a stone. This action is a response to Zeus's attempt to devour their children, as he was afraid that one of them would overthrow him, just like he had overthrown his father. Rhea's anger at Zeus's lack of compassion and his mistreatment of their children leads her to deceive him and protect their youngest child, Zeus's brother, by pretending that she is giving him the baby to devour but actually substituting it with a stone.
