Final answer:
Using "apostrophe" in The passage from 'To Autumn' uses apostrophes to personify and bring to life the season of autumn, encouraging the reader to appreciate its unique beauty.
Step-by-step explanation:
The passage from "To Autumn" by John Keats uses apostrophes to make autumn feel present to the reader. An apostrophe is a rhetorical device where the speaker addresses a dead or absent person, an abstract idea, or an inanimate object as if it were capable of understanding. In this poem, Keats personifies autumn as a being that can possess music as spring does. The reader is encouraged to acknowledge autumn's unique beauty and contributions to the cycle of the seasons, shifting the focus from what is missed (the songs of spring) to what is presently valuable (the music of autumn).
