What is Icarus's main problem in the story?
He does not like the king.
He is too prideful in his behavior.
He does not know how to build things.
He is better at flying than his father.

He is too prideful in his behavior

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
