Read the excerpt from Act III of The Importance of Being Earnest. Lady Bracknell. [With a shiver, crossing to the sofa and sitting down.] I do not know whether there is anything peculiarly exciting in the air of this particular part of Hertfordshire, but the number of engagements that go on seems to me considerably above the proper average that statistics have laid down for our guidance.

What Victorian social code is reflected in Lady Bracknell’s disapproval of the number of engagements?

the belief that romance should play a large role in engagements
the perception that quick engagements go against religious beliefs
the belief that engagements and marriages should follow social rules
the perception that it is important to marry within one’s social class
