Which of the following is an effective way to prevent moisture problems and mold growth in the kitchen?

Installing energy-efficient windows is an effective way to prevent moisture problems and mold growth in the kitchen because these windows help to create a better temperature balance and reduce condensation. Energy-efficient windows are designed to minimize the transfer of heat between the inside and outside of the home. This not only enhances energy efficiency but also limits the potential for moisture buildup, which can occur when warm, moist air comes into contact with cooler surfaces, such as poorly insulated windows. By reducing condensation, the likelihood of mold growth is also diminished, leading to a healthier kitchen environment.

The other options do not contribute effectively to moisture control. Using curtains for windows does not address the underlying issues of insulation or condensation. Choosing carpet for flooring can exacerbate moisture problems, as carpets can trap humidity and are often difficult to clean, making them less suitable for kitchen environments where spills are likely. Neglecting ventilation is counterproductive in a kitchen, as proper airflow helps to remove excess humidity generated during cooking and dishwashing, which is essential in preventing mold growth.
