Answer: This situation depends on the result of the overall competition. Such as the total score 120. However, due to the difficulty of the topic, the highest score of the overall exam is less than 50 points, and the number of people is small. Then, this score is more than 40 points. If the topic is generally difficult, the highest score will be more than 80 points, and the number of people will be quite large. Then the passing score will be above 80 points or even above 90 points.
