Arrange the following factors that contribute to social mobility in a meritocratic system from most to least influential: A. Individual effort, B. Family background, C. Educational opportunities, D. Societal structures.

In a meritocratic system, individual effort is often seen as the most influential factor in social mobility because it emphasizes personal hard work and determination. However, family background plays a significant role too, as it can provide resources, support, and encouragement that make individual effort more effective. Educational opportunities are also crucial, as access to quality education can open doors for advancement and help individuals develop skills. Lastly, societal structures, such as laws and economic systems, can either support or hinder mobility, but they are often less directly impactful on a personal level compared to the other factors. For example, a student from a supportive family who works hard and has access to good schools is likely to achieve more than someone without these advantages, even if both live in the same societal structure.
