  during pregnancy.
  doctors wrote an average of three prescriptions per pregnant woman,
  including drugs that had not been proven to be safe during pregnancy.
  doctors wrote an average of 38 prescriptions per year for known teratogenic
  drugs.

Question 2

  Environmental changes in climate are responsible.
  Physicians routinely check for neural-tube defects at birth, thus causing
  the decrease.
  Cereals and breads in the United States and Canada are now fortified with
  folic acid.
  Europeans are genetically predisposed to neural-tube defects.
