1. Much of the power of a villanelle, the form in which this poem is composed, resides in its repeated lines and their subtly shifting meaning over the course of the piece. How do Thomas's repeated lines change from stanza to stanza? You may consider theme, mood, imagery, and even grammatical structure to support your answer.
2. How do you interpret the images of natural forces that Dylan Thomas connects to the men described in the middle stanzas? Choose a stanza and explain how the particular metaphor develops the poem's themes.

3. Discuss the recurring images of light and darkness in the poem. What multiple meanings might these motifs convey? Explain, focusing on a specific passage or set of images.

I need the answers for these 3 questions from the poem do not go gentle into that good night by Thomas​
