Answer:
The evidence from the text that best supports the theme that it is better if the truth comes out is:
This unhappy secret must be disclosed; they must have a complete understanding between them, which is impossible with all this concealment and falsehood going on.
Step-by-step explanation:
Mrs. Linde is an old friend of Nora's, a main character in the play "A Doll's House". Nora is keeping a secret from her husband, a sexist and authoritative man who treats her as his inferior. Krogstad, a former boyfriend of Mrs. Linde's, has written a letter to Nora's husband in which he tells the truth. From the passage we learn that Mrs. Linde, instead of asking Krogstad to get hold of the letter before it is read, asks him to leave the matter alone. It is her opinion that truth should come out. Perhaps Mrs. Linde believes that Nora will only be free when there is nothing more to hide. As long as there is a secret, her husband will have power over her, will control her. The passage that best represents the opinion that it is better if the truth comes out is:
This unhappy secret must be disclosed; they must have a complete understanding between them, which is impossible with all this concealment and falsehood going on.
