Why was franz in a great dread of scolding that day?

Franz was in great dread of scolding that day because he had not prepared for his lesson and was fearful of disappointing his teacher. He was anxious about being unprepared to answer questions, particularly since he knew the class was important and his teacher had high expectations. This fear of reprimand created a sense of pressure and worry, making him dreadfully uneasy about attending school.
