Hi, I am looking for some interesting (multiple choices type) quiz questions that are related to biology. The quiz participants include mostly recent college graduates of diverse background from biology to engineering to mathematics. The audience also come from diverse background. In general, they are almost all layperson. So, the quiz questions cannot be very difficult biology questions. I have no idea what kind of question I can ask, does anyone have any interesting questions related to biological science that even layperson could understand (and interest to most people)? What I am looking for are questions that are simple enough yet not stupid, and can be anything related to biology (history of it, biologists, simple medical facts, etc.) As an example of what I am looking, I have a physical science question that (most) people could understand and find interesting: Someone in Australia pulls the plug from a washing basin. The water drains from the basin, causing a whirl or eddy. In which direction does the water turn ? a. Always clockwise, because of the Coriolis force. b. Always counterclockwise, because of the Coriolis force. c. Sometimes clockwise, sometimes counterclockwise. Anyone who can point to online resource is also very much appreciated. Thank you.
