Which is the refrain of "Do Not Go Gentle Into That Good Night," by Dylan Thomas?
A. Old age should burn and rave at close of day; Rage, rage against the dying of the light.
B. Blind eyes could blaze like meteors and be gay, Rage, rage against the dying of the light.
C. Wild men who caught and sang the sun in flight, And learn, too late, they grieved it on its way,
D. Do not go gentle into that good night. Rage, rage against the dying of the light.
