. Read the excerpt from act 2 of A Doll's House.

Mrs. Linde: Listen to me, Nora. You are still very like a child in many things, and I am older than you in many ways and have a little more experience. Let me tell you this—you ought to make an end of it with Doctor Rank.

Nora: What ought I to make an end of?

Mrs. Linde: Of two things, I think. Yesterday you talked some nonsense about a rich admirer who was to leave you money—

Nora: An admirer who doesn't exist, unfortunately! But what then?

Mrs. Linde: Is Doctor Rank a man of means?

Nora: Yes, he is.

Mrs. Linde: And has no one to provide for?

Nora: No, no one; but—

Mrs. Linde: And comes here everyday?

Nora: Yes, I told you so.

Mrs. Linde: But how can this well-bred man be so tactless?

Nora: I don't understand you at all.

Mrs. Linde: Don't prevaricate, Nora. Do you suppose I don't guess who lent you the two hundred and fifty pounds?

What is the dramatic irony in this passage?

The audience knows that Nora and Doctor Rank are having an affair, but Nora denies it.
The audience knows that Mrs. Linde is jealous of Nora, but Nora does not know this.
The audience knows that Krogstad loaned Nora money, but Mrs. Linde does not know this.
The audience knows that Doctor Rank loaned Nora money, but Nora denies this.

Mrs. Linde suspects that Doctor Rank is the one who lent Nora the money, but Nora denies it. The audience knows that Nora is lying, and that Krogstad is the one who actually lent her the money. This creates a sense of dramatic irony, as the audience is aware of something that the characters are not.
