What can be reasonably deduced about the traditional culture of japan from this portion of the story?

a. Japanese believe in something like heaven and call it "Yomi"

Explanation: this is a description of a fisherman that is going fishing at night and when he returns to his home at dawn. When he was returning to his home he felt a warm wind, a smell of flowers, a really joyful music and that's why he thought that he was lost or maybe death and be in the Land of Yomi because his home was never like that. That's why we can deduce that Yomi is a sweet and wonderful place when you die.

the answer should be:

the intervention of the supernatural gives gilgamesh hope that he will defeat humbaba.

"the sandy walls seemed to collapse in on themselves"

and

"the bloodshot waters seemed to have no bottom"
