Answer:
.
Step-by-step explanation:
In stanzas four and five, the poet continues to highlight the contrast between the caged bird and the free bird. In stanza four, the free bird's thoughts are centered around the pleasures of nature, like the gentle trade winds through trees and the prospect of worms on a bright morning lawn. These thoughts emphasize the free bird's close connection with the environment and its carefree spirit, symbolized by claiming the sky as its own. On the contrary, stanza five delves into the caged bird's mindset, expressing its yearning for freedom. The caged bird's presence "on the grave of dreams" and its piercing "nightmare scream" underline its captivity and pain. This sharp distinction amplifies the theme of confinement versus liberty, with the caged bird's constrained existence contrasting profoundly against the free bird's uninhibited existence amidst nature's splendors.
