Anne is blue. Dave is quiet. Erin is quiet. Gary is quiet. If someone is red and not rough then they are not white. If someone is not rough then they are not smart. If Dave is red and Dave is not blue then Dave is quiet. If Erin is young and Erin is not rough then Erin is quiet. All quiet, rough people are not white. White, rough people are not blue. If Dave is not white and Dave is not quiet then Dave is not red. If someone is not quiet then they are not smart.
Erin is young.
