The teacher introduces himself as "teacher li" . He tells the class that the test is for placement and that the results will not be counted in his final evaluation of the student. The teacher asks the student if he is interested in being a representative of math. The student says he is, but the teacher tells him that he is not brave enough to submit a blank paper for the test. He also tells the student that he does not know his name and that his memory is not up to date. He says that he will let the student "start from scratch" and will select the student to represent math.
