Which of the following factors is most likely to hinder upward mobility within a social stratification system?

One major factor that can hinder upward mobility within a social stratification system is limited access to quality education. Education is important because it provides the skills and knowledge needed for better job opportunities. If a person comes from a low-income family and cannot afford a good school, they might not receive the same chances as someone from a wealthier background. For example, a student in a poorly funded school may not have access to advanced courses or experienced teachers, making it harder for them to pursue higher education and better jobs later on. Without these opportunities, breaking out of a lower social class becomes much more difficult.
