I do not believe you would capitalize "golden retriever" . Yes it's a noun , but only proper nouns are capitalized .
Answer: i think it is 1 and 5
1) What happened
2)What is the subject
3)<span>What about the main character</span>
In the book, Percy Jackson and the Lightning Thief, Annabeth Chase has her heart set on going on a quest.
It is said in the book several times that Annabeth longs to go on a quest. She says that she had only been outside Camp Half-Blood a couple times and longs to be out there again. <u>She desperately wants to join Percy Jackson on his quest to find the lightning thief.</u>
<u></u>
I hope this helps you out! There are other things that she wanted in the book, but this is what she mainly wanted and the most emphasized desire.
