Which environmental condition can promote increased mold growth indoors?

High temperatures
Low humidity
Exposure to sunlight
Inadequate ventilation

The correct answer is: Inadequate ventilation

Inadequate ventilation is a significant factor that can promote increased mold growth indoors. Mold thrives in environments where moisture levels are high and air circulation is poor. When ventilation is insufficient, humidity can build up, particularly in areas like bathrooms, kitchens, and basements. This accumulation of moisture creates an ideal environment for mold spores to settle and proliferate, as they require dampness to grow. In contrast, high temperatures alone do not guarantee mold growth, as low humidity can negate the warmth's impact. Similarly, exposure to sunlight, which typically inhibits mold growth due to ultraviolet light, would not contribute positively to mold proliferation. Therefore, ensuring proper ventilation is critical in maintaining a healthy indoor environment and preventing mold infestations.
