    DinaM asks:
    OK so I take one of the quizzes and I select an
    answer which turns out to be incorrect, however,
    the correct answer was the same as the
    (incorrect) answer I chose...to the number. Just
    wanted to point that out in case it's
    missing something.

    I'm noticing a few typos in these quizzes as
    well because another one I took had an
    incorrectly placed apostrophe ( ' ) before
    the (correct) answer and I think I ended up
    getting the wrong answer because of this. If
    there isn't supposed to be one, please fix
    that and if there is, there was nothing in the
    video explaining that and why...so yeah

    thanks
