Arrange the following concepts related to social mobility dynamics in the correct sequence of influence from individual to societal level: A) Individual achievements, B) Economic conditions, C) Social stratification, D) Societal changes.

To understand social mobility dynamics, we can arrange the concepts from individual to societal level in this order: A) Individual achievements, B) Economic conditions, C) Social stratification, and D) Societal changes. Individual achievements, like education and job success, are the starting point because they directly influence a person's ability to move up in society. Next, economic conditions, such as job availability and income levels, shape the opportunities individuals have to succeed. As more individuals achieve success or face barriers, social stratification occurs, which is the way society organizes people based on their economic status and achievements. Finally, these individual and economic factors lead to broader societal changes, such as shifts in policies or cultural attitudes, which can further impact social mobility for everyone.
