Final answer:
The top two leading causes of death among teenagers are motor vehicle accidents and drug overdoses, with head and traumatic brain injuries being a significant factor
Step-by-step explanation:
The top two leading causes of death among teenagers are motor vehicle accidents and drug overdoses. In 1999, motor vehicle crashes were the leading cause of accidental death, but by 2014, drug overdoses, particularly from heroin and opioid painkillers, surpassed car accidents. Additionally, factors like head and traumatic brain injuries, often resulting from these accidents, contribute significantly to teenage mortality. Recognizing these risks is important for implementing strategies to reduce such fatalities.
