Number of Moons Orbiting Each Planet

I was very new to this site when I made these quizzes. After creating the original (the one you linked) I realized I had made some mistakes, and for some reason decided to make a new quiz instead of just editing the old one. Now that I've been on this site for several years it seems pretty stupid though. It says that I created this quiz just a few days ago, but in reality I had made it at the same time as the other, and recently chose to update this one, since it was already more accurate. Hope that answers your question, it certainly does seem a kind of strange thing to do.
