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.
Using what you have read and what you already know to make a judgement about what something means.
A fault is defined as a crack or fracture in Earths crust along which rock on one side has moved relative to rock on the other.
The setting of "Marigolds" is during the depression or the 30s. You know this because the story says, "The depression that gripped the nation was no new thing to us" and "the black workers of rural Maryland had always been depressed".
