On The scarlet letter by Nathaniel Hawthorne

The final chapter offers three explanations for the bloody “A” etched on Dimmesdale’s chest. Explain what each of the three possibilities are, according to the narrator, and answer the following questions: Why does Hawthorne chose to leave the reason ambiguous? What does this ambiguity offer to the reader or to the narrative? If you were Hawthorne, would you have made the same choice, and why? And finally, which of the three explanations do you mind most likely, and why? Be sure to answer in terms of this narrative.
