premise: The Grand Prix des Frontières was a motor race held at a street circuit in Chimay, Belgium. The race was created by Jules Buisseret, who was also responsible for the circuit's existence. The first event was held in 1929 and was discontinued after the 1972 event for safety reasons.
hypothesis: The Grand Prix des Frontières was a race that started in 1929, and it was discontinued a year after that
reason: It was discontinued in 1972, not a year after 1929, so my statement is incorrect
