Hi! Hope this works! I haven't seen the podcast but, I think this should be the answer.
The reader learns that Mars is a major character that is concerned about the disappearance of his friends and no one is listening to him.
Congrats on your first question!
Gentle or freindly critisism
Answer:
"dead, and with its head"
Explanation:
Internal rhymes - A rhyme involving the middle word and the last word in single line.
The example would be dead, and with its head.
This is the integral rhyme because a word in the middle of the line (dead) and a word at the end of the line (head) rhyme
Reasons its not the other answers.
It's pretty obvious that it is not the other answers as none of the words rhyme
snicker and snack don't rhyme
galumphing and back don't rhyme
one and two don't rhyme
