Answer:
“You don’t know what that letter can bring upon us.”
Explanation:
The evidence that supports the inference that Nora is afraid of what Torvald will say if Krogstad tells him about her forgery is “You don’t know what that letter can bring upon us.”
From the excerpt, it is clear that Nora is scared of what would happen if her forgery is discovered and she is aware that the letter would ruin them both if Torvald finds out about it.
