She touched the doorknob in a classroom because it's a communicable disease.

Answer: She touched the doorknob in a classroom.

Explanation:

Communicable diseases are the ones that get spread from one person to other. Since a doorknob in a classroom is touched by many students throughout the day, the doorknob carries a lot of germs on it. Therefore, the reason for her cough and runny nose is that Amalia touched the doorknob in her classroom.
