Final answer:
Jack Will did not paint anything on his sled in gold letters in the book 'Wonder'. There may be confusion as this event is not depicted in R.J. Palacio's book.
Step-by-step explanation:
In the book Wonder, Jack Will does not paint anything on his sled in gold letters. The question seems to be based on a misunderstanding as there is no mention of a sled being painted by Jack Will in the Wonder book by R.J. Palacio. The book primarily focuses on the life of a boy named Auggie Pullman who has a facial difference and navigates social challenges in school.
