Final answer:
The refrains in the excerpt emphasize the importance of resisting death. The rhetorical language in the poster emphasizes the idea that every minute counts in the war effort.
Step-by-step explanation:
The refrains in the excerpt from "Do not go gentle into that good night" emphasize the importance of resisting death. The repeated lines "do not go gentle into that good night" and "rage, rage against the dying of the light" convey a sense of urgency and encourage the reader to fight against the inevitability of death. The refrains serve to reinforce the message of the poem and strengthen the emotional impact of the poet's plea to his father.
The rhetorical language in the poster has the effect of emphasizing the idea that every minute counts and that viewers should be contributing to the war effort at all times. The statement "every minute counts!" reminds the reader that every day is precious and that valuable lives are being lost in the war. It serves as a call to action, urging viewers to make a meaningful contribution to the production and ultimately help win the war.
