A teacher grades American history exams and returns them to the students. She asks if there are any questions about the test. One student insists the exam was unfair because of some of the questions. The teacher says it's important to study hard, that all the students had the same test, and that students should be expected to remember everything they have learned about history from other teachers and always be prepared to be tested on it. Infer what the student's original claim might have been and what counterclaim the teacher made in response.
