Answer:
The physical elements—the forest.
Step-by-step explanation:
An allegory is a narrative in which certain characters, figures or events are used as representations of deeper ideas and principles. Allegories are most commonly used in order to teach or explain a moral lesson to the reader. In "Young Goodman Brown," one of the allegorical elements is the forest. The forest is not only the setting of the story, but it is also used as a way to represent the hypocrisy and dark impulses of the villagers.
