That was goofy. Some of the questions tested perception with an optical illusion challenge, others were just knowledge questions. What does knowing that smells are connected to the limbic system, have to do with being able to smell them? I also didn't like the question where you ranked loudnesses of sounds that can vary widely. How *many* leaves are rustling? Is the motorcycle two-stroke or four-stroke, what volume does it displace, and does it have street legal exhaust? For instance.
