Survival Skill-- Which of the following isn't a method used to start a fire without a match

( ) the soda can and chocolate method
( ) the battery method
( ) the animal dung method

Animal dung... It is used to keep a already started fire going longer...

Supposedly, one uses the chocolate, which is a very fine abrasive, to polish the convex bottom of the soda can to produce a converging mirror. It wouldn't work in any real survival situation, but folks like to pretend. I'd go with dung on a written exam, but soda on the practical.
