demographic transition quiz

So today in human geo we took the demographic transition quiz, based off of the article he gave us like last week. In the beginning of class Mr. Schick gave us 10 minutes to study and review everything. To study I made a quizlet last Friday and studied a little bit over the weekend. I know I usually say this, but I think I did a pretty decent job on the quiz like the lowest I could get would probably an 80 or something. Anyways there was one question on there that had me absolutely stumped, like I looked at it and reread it like ten times and I couldn't figure out what was wrong with the statement. So, I just left it blank lol. After I was done with the quiz i took my glasses off and Mr. Schick came over and put them on and proceeded to call me legally blind, which is VERY accurate. Then when everybody was done taking the quiz, we learned that it was Mr. Schick's birthday and he talked about exams week.
