Canadian actor Dashan, once drive outside Beijing, was stopped by a traffic policeman. Dashan asked: "How many kilometers per hour is fine?" The traffic police said: "A fine of 80 kilometers per hour is a fine. " Dashan said: " I've only driven for half an hour, and I haven't reached more than 50 kilometers. "The traffic police stunned. Dashan explained again:" So, in the remaining half hour, I only run 29 kilometers. You may wish to follow me. One meter, not only did I admit punishment, but I also asked you to eat mutton lamb! "The traffic police heard it and couldn't help crying and laughing. What is the correct interpretation of Dashan in this passage? ["The speed per hour spoken by traffic police is based on hours, but Dashan thinks it is an hour's journey.", 'He ran 50 kilometers in the first half and 29 kilometers in the second half.', 'He made a logical mistake of "stealing the concept".', 'He is a logical song with no black humor.']
