I didn't finish the test, my brain caught fire, but I'm not sure if I could get the taiko question right and, well, I teach people about taiko. Part of the problem is that what taiko means in North America is very different from what it means in Japan. It's simply the japanese word for any drum at all. Kumidaiko is the modern form of playing together in an ensemble, which is also an important part of modern taiko. They are also not always super loud, since I don't consider okedo that loud, but they're still part of wadaiko. So I'm not quite sure what you wanted as an answer to your question.
