3. When you have a head cold, through which labelled structure can fluids draining from your sinuses affect hearing? 

4. If your aged grandparent had difficulty in hearing you, especially when the TV is on in the background, in which structure do you think the hearing problem is likely to be in? 

5. If you had normal hearing but had difficulty in identifying whether a sound was coming from in front of you or behind you, what structure do you think would be affected?
