The answer is: Elizabeth’s more progressive attitudes can stand out.
In Jane Austen's "Pride and Prejudice," Lady Catherine is depicted as a strict person who contrasts with Elizabeth's indocility and reinforces the latter's qualities. Lady Catherine comes from a noble family since she is the daughter of an earl. As a consequence, she is very demanding as regards social behavior and society rules, which disagrees with Elizabeth's lighthearted and energetic personality.
