Answer:
Dramatic Irony.
Explanation:
Dramatic irony is when a scene occurs which the main character is not acknowledged of what is/has happened.
Following Gatsby's death, Nick and Jordan have a famous phone call in which she chastises him and calls him dishonest. She adds that no one had ever left her the way he did and adds that he is a "careless driver". The Merton College Library is supposedly the place where Jay Gatsby got his education and that is why he calls himself and Oxford man.
