[It is winter. A bell rings in the hall; shortly afterwards the door is heard to open. Enter NORA, humming a tune and in high spirits. She is in outdoor dress and carries a number of parcels; these she lays on the table to the right. She leaves the outer door open after her, and through it is seen a porter who is carrying a Christmas Tree and a basket, which he gives to the maid who has opened the door.] Nora: Hide the Christmas Tree carefully, Helen. Be sure the children do not see it until this evening, when it is dressed. [To the porter, taking out her purse.] How much? Porter: Sixpence. Nora: There is a shilling. No, keep the change. [The porter thanks her, and goes out. Nora shuts the door. She is laughing to herself, as she takes off her hat and coat. She takes a packet of macaroons from her pocket and eats one or two; then goes cautiously to her husband's door and listens.] Yes, he is in. [Still humming, she goes to the table on the right.] –A Doll’s House, Henrik Ibsen Which inference about Nora does this passage best support? She is a very happy and thoughtful person. She treats others with disrespect and can be very selfish. She is lost in her own world, which gives her great happiness. She is filled with shame that she tries to hide from her husband.
