Problem: Nathaniel Hawthorne's "The Scarlet Letter" is a vivid (and accurate) portayal of life in Puritan New England. The prejudices, superstitions and institutions of the society are expressed so well that contemporary readers, who have little knowledge of New England's history, are able to feel the oppression and religious pressures that were common in that society. Indeed, this work is comparable (if not superior) to Arthur Miller's Crucible.
Solution:
Positive
