10. Which of the following is NOT a reason high socioeconomic status lengthens life expectancy? Wealthy people are more likely to live in safe neighborhoods. Wealthy people are more likely to obtain regular medical and dental care throughout their lives. People with greater financial resources are more likely to consume fresh foods and a healthier diet. People of high socioeconomic status are more likely to drive cars.

The question is asking for the option that does NOT contribute to the lengthening of life expectancy in people with high socioeconomic status. The first three options (A, B, and C) all describe benefits that can lead to a longer life: living in safe neighborhoods reduces the risk of accidents and violence, regular medical and dental care can prevent and treat illnesses, and a healthier diet can prevent diseases and promote overall health. However, the last option (D) does not necessarily contribute to a longer life. While driving a car can provide convenience and freedom, it can also lead to accidents and injuries, which can shorten life expectancy. Therefore, the answer is D.
