Final answer:
Miss Prism and Chasuble serve important functions in The Importance of Being Earnest. Miss Prism adds humor while Chasuble represents morality and religion.
Step-by-step explanation:
Miss Prism and Chasuble are two characters in Oscar Wilde's play The Importance of Being Earnest. They serve important functions within the story. Miss Prism is a governess and plays a comedic role in the play. She is responsible for the mistaken identity plot when she leaves the baby in a handbag. Her character adds humor and contributes to the satirical nature of the play.
Chasuble is the local rector in the play. He acts as a symbol of morality and religion. His interactions with the other characters, especially Miss Prism, highlight the hypocrisy and superficiality of society.
