What is a potential drawback of roller shades?

1. They are unable to block light

2. They can interfere with ventilation when closed

3. They are very expensive

4. They cannot be decorated

The correct answer is: They can interfere with ventilation when closed

Roller shades can indeed interfere with ventilation when closed, which is a notable drawback. When the shades are drawn down, they completely cover the window, restricting airflow and preventing fresh air from entering the space. This can be a significant consideration in rooms where ventilation is necessary for comfort or air quality. While roller shades have the advantage of being an affordable and minimalistic option for light control, they don't allow for the same level of air movement that open or differently styled window treatments might provide. This limitation can lead to a stuffy atmosphere, especially in warmer climates or in areas where windows are kept closed for extended periods. The other possible answers address attributes that are either not true or not commonly recognized drawbacks of roller shades, making the focus on interference with ventilation particularly relevant when analyzing their limitations as a window treatment option.
