Answer: It reinforces the idea that all people, not just the speaker's father, should fight against death.
Step-by-step explanation:
The repetition of "men" preceded by an adjective in the excerpt from "Do Not Go Gentle into that Good Night" reinforces the idea that all people, not just the speaker's father, should fight against death. This repetition emphasizes the idea that death is a universal experience that affects people from all walks of life, and the speaker is hoping that by sharing his experiences, he will be able to convince others to fight against the dying of the light and the end of life.
