Answer/Explanation:
on number 2 I would recommend you say "because the throne and responsibilities of a king were forced upon him" after everything you have already written.
for number 4 I would say that ET is about relationships between aliens and humans and between humans and other humans and the conflicts between characters during the quest to get ET home.
I don't know if those are too long, but that is what I would say.
I honestly havent read the book but it looks interesting so once i read it I can answer your question
Characterization is when the author reveals the personality of the characters; Direct characterization is when the author flat out TELLS the audience what the personality of the characters are.
