Charlie is quiet. Charlie is not round. Charlie is white. Dave is big. Fiona is not quiet. Gary is cold. Gary is white. If Fiona is white and Fiona is young then Fiona is not round. All white things are quiet. All big things are white. If Dave is red then Dave is young. All young things are not cold. All round, red things are not cold. White, quiet things are red. If something is round and not white then it is not red.
Charlie is big.
