Answer to Question 1

B
Visual changes often include reduced visual fields, increased glare sensitivity, impaired night vision, reduced accommodation, reduced depth perception, and reduced color discrimination. Many of these symptoms occur because the pupils in the older adult take longer to dilate and constrict secondary to weaker iris muscles. Color vision decreases because the retina is duller and the lens yellows.

Answer to Question 2

C
Infants need an energy intake of approximately 108 kcal/kg of body weight in the first half of infancy.
