Answer:
Carlos's family exemplifies intergenerational mobility.
Step-by-step explanation:
Intergenerational mobility refers to the change in a family's social status. In other words, how different generations of the same family rise or fall in social positioning. As we can see, Carlos's family's status improved over time. His grandfather was an immigrant who had only six years of schooling, his father finished high school, and Carlos himself graduated from medical school. His grandfather worked as an agricultural worker, his father as a clerk, and Carlos has a thriving medical practice. His family's social position has increased.
