Anne is smart. Erin is rough. If Anne is blue then Anne is young. If Erin is big then Erin is young. All green, quiet people are not smart. Smart people are blue. If Erin is not quiet then Erin is not green. If someone is young then they are rough. If someone is young and not rough then they are green. If someone is young and not green then they are smart.
Erin is not quiet.
