I am not sure about the first question, I cannot help you with that one, sorry. :/
However, the second question I know. Ragnarok is A), an apocalyptic prophecy, a Norse prophecy stating when the end of the world will come.
Answer:
I believe the children are playing outside.
Explanation:
"till the little ones are weary"
"the sun does descend"
"and our sports have an end"
To me, it sounds like the children played outside till sundown. If I'm wrong, please forgive me! I haven't been to school since I graduated.
