Read the excerpts from different sections “the scarlet ibis.”

although doodle learned to crawl, he showed no signs of walking, but he wasn’t idle. he talked so much that we all quit listening to what he said. it was about this time that daddy built him a go-cart and i had to pull him around. at first i just paraded him up and down the piazza, but then he started crying to be taken out into the yard and it ended up by my having to lug him wherever i went. if i so much as picked up my cap, he’d start crying to go with me and mama would call from wherever she was, “take doodle with you.”

he’d nod his head, and i’d say, “well, if you don’t keep trying, you’ll never learn.” then i’d paint for him a picture of us as old men, white-haired, him with a long white beard and me still pulling him around in the go-cart. this never failed to make him try again.

based on these excerpts, what best describes the symbol of the go-cart within the story?

it changes from a symbol of youth to a symbol of old age.
it changes from a symbol of success to a symbol of failure.
it changes from a symbol of hope to a symbol of desperation.
it changes from a symbol of freedom to a symbol of captivity.
