If you are in k12, the answer is:
"Ben looked forward to discovering which route they would take and which unique places they might visit this year."
Answer:
Simile: comparing a float aways down a stream to time
Metamorphosis: when it said the life, youth, wealth was renowned and the processes to what it was. that was the big change.
This sentence means a character had decided upon a certain action for a problem in their head. however other characters (the peers in this example) bestowed an act of kindness or "did something nice" for this other characters in hopes that he/she would change their mind. A good example would be if you upset your parent by acting up and they said no to a sleepover. you would do chores or act kindly towards them in order to try to get them to change their mind and say yes.
I would say that the pair of lines from the passage that contains a change in intonation is the first one:
But all the time / I'se been a-climbin' on
Because it shows a change in the tone of a poem.
