Text: The creator of PEES and its first principal was Krzycho Jedynak, a former junior high PE teacher in Potylica, a computer games fan and the winner of, as we could read in the beautifully printer brochure, 'a local Amiga gaming championship'.
Entailment: Jedynak used to teach physical education for a junior high.
Contradiction: There has never been anyone who taught PE in junior high.
