None of the available choices were correct so points are being awarded to those who either guessed correctly or read the author's mind. There are valid arguments to be made for claiming that 0, 4 or "syntax error" was the correct answer...27 is obviously just flat out wrong.

I know the point is supposed to be increasing our knowledge by answering/researching the questions and not racking up points, but that theory goes out the window when you keep score...especially on a 3-pointer.
