“How does the council know when someone breaks a rule? What was the purpose of the announcement made on page 23?”
Although it does not striaght out say it, it seems that the council is ‘all knowing’ as in they see all, they are always watching. It could be how you interpret this but to me it seems as if they have cameras that are watched 24/7.
Later in the book Jonas talks about having to ‘report’ something, his mother (unit) says he already has just by saying it.
The purpose of the announcement on page 23 (ATTENTION. THIS IS A REMINDER TO ALL MALE ELEVENS THAT OBJECTS ARE NOT TO BE REMOVED FROM THE RECREATION AREA AND THAT SNACKS ARE TO BE EATEN NOT HORARDED) was aimed at Jonas because while playing catch with his friend Asher, he noticed a change in the apple and snuck it home to look it over and try to understand what it was he had seen.
The announcement was just another point of how the council always seems to know what is going on anywhere in the community. How could they know that someone actually took the apple home and did not just eat it unless they have some sort of ‘eyes’ all over the community?
How would you feel knowing that whatever you did someone was watching you, observing to make sure you didn’t break any rules?
