Answer to Question 1

c

Answer to Question 2

Prolonged, extreme stress during pregnancy can lead to attention and behavioral problems in children. Jen's prenatal stress can also affect her child's physical, cognitive, and language development. However, Angelina's age puts her child at risk of low birth weight and Down's syndrome. Her poor diet during prenatal development can lead to problems in attention, memory, and intelligence. Also, if Angelina has not consumed adequate amounts of folic acid, her baby is at risk for spina bifida.
