Question 1: 'When Goldie saw the chipmunk she ran gleefully.' - There should be a comma after chipmunk.
Question 2: Prewriting, because you can make a list of things to talk about in the writing and also use charts and webs.
Question 5: Spell checker, because you don't need the grammar, usage, or a synonym of the word, you need the spelling.
Question 6:
It is about a person's life, written by somebody else. You do need research about the person, they are true, and an autobiography is written by the same person the book is about.
Hope I could help!
