Which item is NOT listed as a source of moisture?

Explanation:
Moisture in indoor air mainly comes from things that add water vapor or allow water to evaporate. Showering sends up a lot of steam, which raises humidity. Cooking releases steam from boiling and simmering, again boosting moisture in the room. An aquarium continually loses water to evaporation, contributing ongoing moisture over time. Paint fumes, on the other hand, are about solvents and odors rather than adding water vapor to the air. They don’t significantly increase indoor humidity, so they aren’t considered a moisture source. That’s why paint fumes is the item not listed as a moisture source.
