Answer to Question 1

ANS: C
Because of the greater density of breast tissue, mammography is less sensitive in younger women, which may result in more false-negative results.

Answer to Question 2

ANS: A, B, C
Otitis media is usually caused by an upper respiratory infection with gram-negative bacteria, such as Proteus, Klebsiella, and Pseudomonas. In addition, allergy, exposure to cigarette smoke, mycoplasma, and several viruses may be factors.
