In order to answer this question, you would need to provide the title of the book that you are working from. However, I can help you determine the setting and what types of information might help you answer this question for any book.
First, determine where the story takes place - is it in a small town in the Midwest, New York City, or a fictional country? Think about this location, and all the information that you already know about this type of setting. For instance, if the story is set in a large city, you might know that this means the characters might walk to school, work, or the store instead of driving. They might take a taxi to get to the airport, and they might live in an apartment instead of a house.
Next, figure out the time period of the book. Is the book set in the past, the present, or the future? This will determine how the characters behave, and the plot of the story. For example, if the book is set in 1830, there will be no computers, cars, or even fast food restaurants. The characters might speak differently, and they might have different problems to deal with.
Finally, think about the plot of the story. What happens in the book, and how does the setting (time and place) seem to affect what happens? Setting can change the plot a lot, so make sure you have a complete and thorough understanding of the setting as you read.
