Answer to Question 1

A
Feedback:
Presbycusis is progressive hearing loss that occurs as a result of age-related changes to the inner ear, including loss of hair cells, decreased blood supply, reduced flexibility of basilar membrane, degeneration of spiral ganglion cells, and reduced production of endolymph. Cognitive changes, cellular changes in the outer and middle ear, and deterioration of neural pathways are less likely to be implicated.

Answer to Question 2

A
Feedback:
The primary cause of urinary retention in men is prostatic hypertrophy, which is present to some degree in most older men.
