Answer to Question 1

ANS: D
The infant's eustachian tube is relatively shorter and wider than the adult's eustachian tube, and its position is more horizontal; consequently, pathogens from the nasopharynx can more easily migrate through to the middle ear. The other responses are not appropriate.

Answer to Question 2

ANS: B
If maternal rubella infection occurs during the first trimester, then it can damage the organ of Corti and impair hearing.
