Resources such as Nystrom, Carolyn. 1 & 2 Peter and Jude: 12 Studies for Individuals or Groups: With Notes for Leaders. A LifeGuide Bible Study. Westmont, IL: IVP Connect, 2002. provide leaders' aids/suggested answers to their questions which allow them to ask a bit more complex questions because they aren't completely dependent on the training/skills of the leader. It would be useful to have questions with suggested answers marked in some way so that the person building the lesson can see better if the question is suitable for their group.
