Answer to Question 1

D
Specific acquired immunity occurs only after exposure to a foreign substance.
Acquired immune responses are specific.
Individuals are not born with specific acquired immunity to most antigens; they develop after initial exposure to a foreign substance.
Acquired and natural immunity can occur in response to antigens.

Answer to Question 2

B
Folic acid should be taken prior to the actual pregnancy to protect against neural tube defects in the fetus, because these defects are caused by a folic acid deficiency. It is imperative that all women of reproductive age have adequate folate levels before pregnancy occurs.
Vitamins B6, B12, and C are not recommended as supplements during pregnancy except for a specific deficiency.
