Text: Kazimierz built great castles and towns, codified laws, and created an entire administrative system of governance for the war-torn country.
Entailment: Great castles and towns built, law codification, and creation of an entire administrative system of governance for the war-torn country--we owe all this to Kazimierz.
Contradiction: We do not owe Kazimierz any of the great towns and castles, he was just a common drunk.
