Many of the leading causes of death among teenagers and young adults can be prevented by

• A. Vaccination alone
• B. Lifestyle changes
• C. Medical treatment
• D. Genetic factors

Answer: (B)

Many of the leading deaths in teens and young adults come from risks that can be reduced through everyday safety and lifestyle choices. Unintentional injuries, such as car crashes, drownings, and other accidents, as well as suicides and homicides, are heavily influenced by behavior and environment. Making safer decisions—like wearing seat belts and helmets, avoiding driving after drinking, not using drugs or alcohol when risky situations arise, practicing safe sex, seeking mental health support, and avoiding high-risk situations—can substantially lower these death rates. Vaccines are important for preventing certain infectious diseases, but they don’t address the broad range of leading causes that are tied to behavior and safety. Medical treatment helps after an event occurs, but prevention through healthier lifestyle choices targets the root risks. Genetic factors influence risk, but they’re not something easily prevented through broad lifestyle changes.
