Something Terrible Had Happened

Take for instance the probability of calling a different person each time to answer a question in a big class like this was quite high.

Under such circumstances, the probability of calling upon Qiao Nan to answer the question was as high as fifty percent.

Actually, everyone wanted to avoid being called upon to answer questions. But the interesting thing was, whenever Qiao Nan was called by the professors, she would get the question correct and the professors were very satisfied with her answers.

Many professors felt that Qiao Nan was a good student who was very serious in classes and paid attention to the lessons. They thought that the reason why the principal thought highly of her and wanted the professors to pay more attention to her studies was that she was smart and studious.

They never managed to clear up the misunderstanding.
