Editor’s note: When we made the incision point into linguistics exploration back in October 2017, we promised you no tests. What we really should have promised you are no grades. Take this “final exam” at your leisure – this is untimed, “open-site,” and really just for fun. That said, answers are due by December 31. In the new year we’ll check the submissions and award a free book of bilingual Chinese stories to the reader with the highest score. Best of luck, language nerds!
