The first three answers I think. I read this a month or two ago for k12. So I'm pretty sure it would be the first three. Hope I could help!
You take a story and explain the entire thing with only a couple paragraphs, and you don't want to give away any special details that way a person can know a little about the book and want to read it. Like a "A dog and His Ball" is about a lost dog who doesn't have a family and finds an old ball to play with. You would put this on the back of a book and then people would be drawn to read this book. ( I just made something up so it may not make sense sorry.)
I'm not really sure I understand what you are asking, but I tried to answer the best I could, please let me know if this isn't what you meant.
I think the answer is infinitive.
I would have more time to do things in the real world but i would need to find new ways to entertain myself.
