Answer to Question 1

Strawberries are one of the eight foods (spinach, rhubarb, beets, nuts, chocolate, tea, wheat bran, and strawberries) that cause significant increases in urinary oxalate excretion; therefore straw-berry shortcake may increase urinary oxalate levels. Ginger cookies, cinnamon rolls, and blueberry muffins would not increase urinary oxalate levels.
Answer to Question 2
C

Body weight does not ap-pear to be related to formation of kidney stones.
