Answer: 4. Nature has an elegant appearance in autumn.
Step-by-step explanation:
In her poem, Emily Dickinson describes the nature in autumn. She explains that the trees and fields have changed and are now more colorful than during summer. The field is wearing a scarlet dress, the maple ''a gayer scarf''. She metaphorically describes colors of the leaves and trees as clothes. In the last line, Dickinson states that she should also change her clothes, or she will be considered old-fashioned.
