Question 1 : You are participating in a race. You overtake the second person.

What position are you in?

Answer: If you answered that you are first, then you are absolutely wrong! If you overtake the second person and you take his place, you are second!

Try not to screw up in the next question. To answer the second question, don’t take as much time as you took for the first question.

Question 2 : If you overtake the last person, then you are…?

Answer: If you answered that you are second to last, then you are wrong again. Tell me, how can you overtake the LAST person?!

You’re not very good at this! Are you?
