Dynamic characters in the old man and the sea

I believe that Santiago is dynamic character in "The old man and the sea"

Explanation:

Santiago is an old fisherman in Cuba who, at the beginning of the book, has not caught anything for eighty-four days.  Santiago's quest for the great catch that will save his career. Santiago endures a great struggle with a uncommonly large and noble marlin only to lose the fish to rapacious sharks on his way back to land.  Santiago ends with his spirit undefeated.

Remember a dynamic character also undergoes changes throughout the narrative, due to conflicts he encounters on his journey. A dynamic character faces trials and tribulations, and takes time to learn from his encounters, his experiences, and his mistakes, as well as from other characters.

So if by any chance you think I am wrong let me know and also think back to the story and try to figure out what characters in the book face "trials" and how that person learns from his/her mistake :) you will do great I believe in you!!

The things that are bold are hints of what your answer should be :) <3

the words “strangest” and “unusual” suggest that the narrator is about to tell the story of an odd or puzzling group of people.

very interesting story but where is the question what is actually a question i don't understand
