I believe this depends solely on personal preference. A work of literature that you like may not be good to somebody else, so the way you feel about something makes it either good or bad. I believe I am pretty comfortable determining the quality of literature given that I have read a lot of books and have an overall grasp of each literary era throughout history. It can be easy to critique a text if you are knowledgeable enough about that particular era, style of writing, and general context, but it could also be quite difficult depending on the topic of that work.
The main setting of the book is where the characters of the book are usually at. If they are at the park more than they are at home, then the main setting would be the park.
THe three minor characters are the characters that add the most to the story. If the book is in first person, then one of the main characters is the person talking. But the three people that are in the story most and talked about most are the three main characters.
Hope this helps :)
For the first one:
B.) Historical documents, eyewitness accounts, etc. that provide direct or firsthand evidence about an event, object, person, or work of art.
For the second one:
B.) Her mother stared at her (because "stared" sounds more threatening than "looked").
Hope this helps!
The answer is B. I’m pretty sure of it
