sweet, being japanese made this almost a breeze. they have some general survival questions not related to the game.
there is one that is something along the lines of what percentage of body water can you lose (NOT LOOSE!!!) before you succumb to death
also if you get 100% on the quiz you can be entered into a lottery/raffle to win some other junk. like a expedition trip around japan, a bunch of energy bar/food, a camera, and somethig else i forgot already. it asks for email, phone, and any comments you have
don't get your hopes up, i didn't read he terms but im pretty sure it is japan only
