Dave Is Working on a Problem Solving Task with Five

Dave is working on a problem solving task with five other students from his class. Most of the members on this team are very sociable and they get along very well. They are considering including a new person, Steve, on their team. Steve, although conscientious, is not very sociable. Using your knowledge about social groups, what would you advise this team?

A) not to take Steve because they might not get along very well with him
B) not to take Steve because people who lack social skills are good for routine tasks, but not for problem-solving tasks
C) to include Steve because he might help the team stay focused on the task
D) to include Steve because he might help to create the rapport needed to generate new ideas freely
