Question

Dylan Thomas’ do not go gentle into that good night is using which type of stanzas?

A- couplets
B- Tercets
C- quatrains
D- none

Answer 1

This poem is written in the form of a villanelle. A traditional villanelle has 19 lines split into 5 tercets and a quatrain. And that's what Thomas has in this poem.

Since the question uses the singular noun (which type), the answer is B.

After all, C says "quatrains", and Thomas has just one quatrain as there can only be one quatrain in a traditional villanelle.

Answer 2

I believe the answer should be B. tercets
Tercets are the basic unit of a form known as the villanelle, which follows an ABA rhyme scheme and has two refrains that repeat throughout the poem
I hope this helps:)
