Question

age, rage, against the dying of the light\ is one of two refrains that is repeated throughout the poem to emphasize...
death is like blindness.
that wild men deserve to die earlier than other people.
that his father should embrace life for as long as possible.
he is giving his father permission to die.

Explanation:

This line is from Dylan Thomas' Do Not Go Gentle into That Good Night, a poem addressed to his dying father. The refrain "Rage, rage, against the dying of the light" urges resistance to death, meaning the speaker wants his father to hold onto life and fight against its end. The other options are inconsistent with the poem's core message: the poem does not equate death to blindness, claim wild men deserve early death, or give permission to die.

Answer:

C. That his father should embrace life for as long as possible.
