  True
- B.
  
  False

Mold cannot grow on clean smooth ceramic tiles.
- A.
  
  True
- B.
  
  False
Correct Answer

The key to fungal growth is moisture... no moisture, no growth.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Moisture is a crucial factor for the growth of fungi. Fungi thrive in damp and humid environments, as they require water to survive and reproduce. Without moisture, fungi cannot obtain the necessary nutrients and cannot grow. Therefore, the statement that the key to fungal growth is moisture is true.

It's impossible to make a typical home mold free.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Mold spores are present in the air both indoors and outdoors, and they can easily enter a home through open windows, doors, or on clothing and shoes. While it is possible to control and reduce mold growth through proper ventilation, moisture control, and regular cleaning, it is nearly impossible to completely eliminate mold spores from a typical home. Therefore, it is true that it is impossible to make a typical home mold-free.
