All the answers to the questions are found in the relevant chapter.
For example, Chapter 1 is called Sin and Grace in the Days of the Judges, and these are the questions I set for them:
1. Name some of the things which make the book of Ruth an especially good story.
2. At what time in the history of the nation of Israel did Ruth live?
3. How was the moral state of the nation at this time described?
4. Find a verse elsewhere in the Bible that speaks of the Lord Jesus Christ as the Judge.
The book was written with teens or young adults in mind, but I'd say it's a good read for any age.
