According to the text, a 2014 study by two economists who examined the effects of the
  MTV show, 16 and Pregnant, concluded that:

a. The program has caused an increase in the rate of teen pregnancy and should be
  banned from the airwaves.
  b. The program has caused an increase in the rate of teen pregnancy but should be
  controlled through education efforts to discourage teens from watching the show.
  c. The program has caused an increase in the rate of teen pregnancy and has cost
  taxpayers over 1 billion in medical infrastructure costs.
  d. The program is responsible for a decrease in the rate of teen pregnancy.
  e. The program should be declared to be legally obscene because it
  meets the three-pronged test for legal obscenity.
