Which statement describes how humidity affects evaporative cooling?

Explanation:
Evaporative cooling depends on sweat turning into vapor and leaving the skin. The air’s ability to take up more water vapor is what drives that evaporation. When the air is very humid, it’s already saturated with moisture, so sweat evaporates more slowly and less cooling occurs. In drier air, evaporation happens more quickly, giving you more cooling. So humidity reduces evaporative cooling. Humidity doesn’t make sweating happen more, and it does affect cooling—high humidity slows evaporation, not increases it.
