A philosophy （哲学）professor walks in to give his class the exam.
Place his chair on  his desk, the professor says to the class,              76．      
“Use everything you’ve learned in that course to prove this        77．    
chair does not exist.” So, pencils are writing but erasers are            78．    
erasing. The students had a hard time proving that this chair             79．    
doesn’t exist except one student, whom spends thirty seconds     80．    
writing his answer, and then turns his paper, which surprises             81．    
his classmate. Time goes by, and the day comes when all          82．    
the students get their final grades. For everyone’s surprise, the   83．    
student who only wrote for thirty seconds gets a highly mark.    84．    
His answer to the question is “What a chair?”                           85．
