What changes inside the airways in the lungs lead to an asthma attack?

"During an asthma attack, the muscles surrounding the airways contract, limiting the amount of air supply to the lungs. The lack of sufficient air supply results in a choking sensation. Asthma attacks induce the secretion of sputum and mucus, also which causes the airway to constrict even more, making the asthma attack worse." - hadassah-med.com

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.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.
