Final answer:
Motor Vehicle crashes account for most of the deaths by unnatural causes in Illinois, and historically, they are a leading factor in accidental deaths. While drug overdose deaths have increased, motor vehicle accidents remain a significant concern. Specific daily figures for teen deaths from such incidents would require current and precise data, which is not provided.
Step-by-step explanation:
The correct answer to the given question is option C: Motor Vehicle. Statistics show that, historically, motor vehicle crashes have been a significant cause of unintentional deaths in Illinois as well as in the United States. Although there has been a substantial increase in drug overdose deaths, especially from heroin and opioid painkillers, over the years, when it comes to accidental deaths by unnatural causes, motor vehicle accidents have been a leading factor.
To answer question 68 numerically, while specific statistics about daily teen deaths due to motor vehicle injuries are not provided in the given information, we can use national data as a reference. If we consider the available data from sources like the U.S. Census Bureau on motor vehicle accidents and fatalities, it can help us estimate the likelihood. Historical trends from such databases might suggest that on any given day, motor vehicle injuries are a significant risk to teen safety, but without current specific numerical data, it is difficult to definitively state that more than 20 teens will be killed from motor vehicle injuries every single day in the United States.
