A person who has what is often called head cold will have difficulty breathing through their nose and will notice that their voice sounds different from when they dont have a cold. Which aspect of the functions of the paranasal sinuses helps explain this?
1. swelling of mucous membrane, and congestion from overproduction of mucus within the sinuses reduces the flow of air through the sinuses, giving that stuffy feeling
2. the air being warmed in the sinuses is becoming overly warmed and dried from fever, affecting the voice
3. congested sinuses result in smaller spaces for the voice to resonate (echo), so the voice sounds different than it normally does

a) 1 only
b) 2 only
c) 3 only
d) 1, 2 and 3
e) 1 and 3
