Final answer:
The unanswered question is regarding the specific effect of humidity levels on perceived air temperature, which the article describes as causing us to feel hotter due to inefficient sweat evaporation.
Step-by-step explanation:
The question which is not answered by the article is: What effect does the humidity level have on the way the air temperature feels? The article thoroughly explains that humidity significantly affects our perception of temperature. High humidity levels hinder sweat from evaporating efficiently, causing us to feel hotter than we actually are because it's the evaporation of sweat that cools us down. Conversely, low humidity can cause discomfort as it dries out mucous membranes. However, the article does not provide a specific answer to how the humidity level affects the actual air temperature felt by individuals.
