It is the future and society has advanced by leaps and bounds, but everything is not perfect, at least not by our today's standards. Children when turn 12 have to take a government test to see how smart kids are and it seems as a very important part of this society's working mechanism. I love the acting of the boy here, he looks so naive not knowing what is going to happen as the show unfolds.
This episode is another critic to today's society in which who ever thinks differently is outcasted or killed by any means.
Twisted ending, I so hate it!
