Answer:
Part A's answer would be:
"turns from side to side due to suffering"
Part B's answer would be:
"like a caged puppy"
Step-by-step explanation:
The meaning of the word "writhes" in this poem most likely means "turning from side to side due to suffering" because writhes means to squirm, or wiggle.
I chose "like a caged puppy" to best describe writhes because when puppies are in cages, they usually move around back and forth, squirming, wanting to get out.
