Answer:
It creates a melancholy tone, as the personification of spring suggests indifference to humans.
Explanation:
Personification is a literary device in which human characteristics are attributed to something non-human (in this case, to spring). Spring wakes up, which is something humans and animals can do, the pronoun <em>she </em>is used to describe it, and it's written with a capital letter. It feels as if spring is represented as a woman with her own name.
The figurative language creates a melancholy tone, as the personification of spring suggests indifference to humans. Spring wakes up, not even realizing that humans are gone. Spring will arrive every year, no matter whether the humans are there or not.
