In A Wrinkle in Time, how does Charles Wallace know that the robotic inhabitants of Camazotz are not actually robots? Please reply ASAP. Thanks

It sounds like you are talking about when the Murrys first
got to Camazotz. Everyone looked very robotic, and the children were outside bouncing
balls and jumping rope in unison. All of them appeared to be robotic, but then they
noticed one boy who was NOT in sync with the rest. Mothers appear, in unison, and
retrieve their children, but the one boy continues to bounce his ball in a pattern that
does not match what the other kids were doing. His mother sees this, grabs him and takes
him into their house. She is obviously very upset, and the ball is left outside. They
take it to the door, the mother denies her child could have done anything not in sync,
but the boy grabs the ball. After seeing more instances of behavior that looks robotic
(the paperboy's perfect paper throwing, for example), Charles uses his ability to feel
what others are feeling, and can tell they are people, not
robots.
