In which poem does the line "Do not go gentle into that good night" appear?

The line "Do not go gentle into that good night" is the opening line of a villanelle by Dylan Thomas, which shares the same title as the line itself. This poem is well-known for its themes of resistance against death and the struggle for life, capturing the speaker’s plea for his dying father to fight against the inevitability of death. The refrain "Do not go gentle into that good night" emphasizes the emotional intensity of this struggle, making it a powerful and iconic line in literature.

The other options represent notable poems but do not contain the quoted line. "Howl" by Allen Ginsberg is a groundbreaking work that delves into the experiences of the Beat Generation and critiques modern society. "The Waste Land," written by T.S. Eliot, is a complex poem that explores themes of disillusionment and fragmentation in a post-World War I world. "The Road Not Taken" by Robert Frost reflects on choices and their effects on life. While these poems are significant in their own rights, they are distinct in subject matter and style from Thomas's work.
