Koresh's group was considering how to approach the general topic of meth labs in their panel discussion. some wanted to discuss the problem on a national scale, but koresh wanted to limit the topic to what was happening within the local area only. they had been arguing this for some time, and group members were getting frustrated. finally, sam suggested that they use a chalkboard, and make a written list of the pros and cons of each option. they did this, and it became clear that the best choice would be to limit the topic to the local area. which function did sam suggest for his group?
