Final answer:
The debate over sex education is centered around abstinence and comprehensive programs. Most U.S. adults support education about safer sexual practices and contraception over abstinence-only education in terms of reducing unintended pregnancies and the spread of STIs.
Step-by-step explanation:
Much of the debate over sex education is over the issue of abstinence as compared to a comprehensive sex education program. Abstinence-only programs focus on avoiding sex until marriage or delaying it as long as possible, without teaching other methods of contraception or prevention of sexually transmitted infections. Research suggests that a majority of U.S. adults support education about safer sexual practices and contraception over abstinence-only education in terms of reducing unintended pregnancies and the spread of STIs.
