Answer to Question 1

ANS: A
The normal pathway of hearing is air conduction, which starts when sound waves produce vibrations on the tympanic membrane. Conductive hearing loss results from a mechanical dysfunction of the external or middle ear. The other statements are not true concerning air conduction.

Answer to Question 2

ANS: C
The nerve impulses are conducted by the auditory portion of CN VIII to the brain.
