5 years ago I also had an issue with the quiz, but the issue I had was that the explanation of yaw, pitch and roll given on the video is incorrect, specifically the instructor seems to have mixed up the pitch and roll explanation. I used this youtube video instead to answer the quiz correctly: https://www.youtube.com/watch?v=pQ24NtnaLl8
The answer accepted in order to pass question 4 of this quiz appears to be the exact opposite of what the correct answer should be. I don't want to violate the honor code, so I can't post what the correct answer and apparently incorrect, but accepted answer are, but if someone contacts me via chat or email I can discuss it further. Suffice it to say, again, that the accepted answer appears to be the opposite of what the correct answer ought to be based on the provided diagram.
