Helmer: Before all else, you are a wife and a mother. Nora: I don't believe that any longer. I believe that before all else I am a reasonable human being, just as you are—or, at all events, that I must try and become one. I know quite well, Torvald, that most people would think you right, and that views of that kind are to be found in books; but I can no longer content myself with what most people say, or with what is found in books. I must think over things for myself and get to understand them. What message does the author express through the character of Nora? A. A person should read books to find knowledge. B. A woman should be a good wife and mother. C. A person should listen to what others say. D. A person should discover truth on his or her own.

In literature or narratives, it is common the author expresses different messages or believes about life through multiple elements including the character's values, actions, and words. In the case presented, there is a short dialogue between two characters the first one is Helmer who believes Nora is a wife and a mother and the second one is Nora who argues she is a "reasonable human being" and she emphasizes she would not believe or be content with people words or even with the information she found in book but instead she "must think over things ... and get to understand them". This shows the author of this literary work aims at showing a person should not read books or listen to other people to find what is true, but instead a person should find out the truth on his or her own, which is shown through the words and character of Nora.
