Answer to Question 1

ANS: B
Gastric acid secretion decreases with aging and may cause pernicious anemia (because it interferes with vitamin B12 absorption), iron-deficiency anemia, and malabsorption of calcium.

Answer to Question 2

ANS: C
Black stools may be tarry as a result of occult blood (melena) from gastrointestinal bleeding. Red blood in stools occurs with localized bleeding around the anus.
