Tony read the following passage in a myth: Young Krishna and his friends played in the fields all day as they watched the calves. One day, as they played, Agasura, an eight-mile long snake, lay down on the path. Agasura opened his mouth widely, determined to swallow Krishna and his friends. The great snake’s enormous mouth looked just like a cave. His tongue looked like a path, and his breath seemed like an eerie warm breeze.

It tells that in this culture, nobility, or being a king, does not always make one good. B. It tells that in this culture, the killing of humans is allowed. C. It tells that this culture has great respect for children. D. It tells that snakes are worshipped in this culture.
