Read the passage from A Doll’s House

Nora: [breathlessly]. Torvald—what was that letter?

Helmer: Krogstad's dismissal.

Nora: Call her back, Torvald! There is still time. Oh Torvald, call her back! Do it for my sake—for your own sake—for the children's sake! Do you hear me, Torvald? Call her back! You don't know what that letter can bring upon us.

Helmer: It's too late.

Nora: Yes, it's too late.

Helmer: My dear Nora, I can forgive the anxiety you are in, although really it is an insult to me. It is, indeed. Isn't it an insult to think that I should be afraid of a starving quill-driver's vengeance? But I forgive you nevertheless, because it is such eloquent witness to your great love for me. [Takes her in his arms.] And that is as it should be, my own darling Nora. Come what will, you may be sure I shall have both courage and strength if they be needed. You will see I am man enough to take everything upon myself.

Nora: [in a horror-stricken voice]. What do you mean by that?

Helmer: Everything, I say—

Nora: [recovering herself] You will never have to do that.

Which evidence supports the inference that Nora is afraid of what Torvald will say if Krogstad tells him about her forgery?

“Do it for my sake—for your own sake—for the children’s sake.”

“You don’t know what that letter can bring upon us.”

“Yes, it’s too late.”

“You will never have to do that.”
