Your cousin is expecting a baby and excitedly tells you that she plans to buy lots of classical music to make her baby
smarter. Which of the following is a reasonable response, based on what you have learned?
A) "Great idea! But be sure to include Mozart, because his music works the best."
B) "Great idea! But play the rock and rap CDs you already have; they'll work too."
C) "Save your money. Studies have not shown that listening to classical music makes babies smarter."
D) "Save your money. Intelligence is 100 percent hereditary, so you can't influence your baby's intelligence after he or
she is born."
