What does the following passage mainly say about Jonas?
"But it means," his mother went on, "that you’ll move into a new group. And each of your friends will. You’ll no longer be spending your time with your group of Elevens. After the Ceremony of Twelve, you’ll be with your Assignment group, with those in training. No more volunteer hours. No more recreation hours. So your friends will no longer be as close."
Jonas shook his head. "Asher and I will always be friends,” he said firmly. “And there will still be school."
