Answer:
Step-by-step explanation:
In "Nothing Gold Can Stay," the effect of the speaker's choice to make the title and the last line the same is to create a sense of circularity and closure. By repeating the phrase "Nothing Gold Can Stay," the speaker emphasizes the theme of the poem, which is the fleeting nature of beauty and the impermanence of life. The repetition of the phrase also serves to bring the poem full circle, suggesting that the cycle of life is continuous and that everything eventually comes to an end. This repetition serves to reinforce the central idea of the poem and gives it a sense of unity and completeness.
