Final answer:
This scenario illustrates structural unemployment, which arises from a mismatch between workers' skills and the requirements of available jobs due to technological changes.
Step-by-step explanation:
In this scenario, where advances in technology make the assembly-line worker's job obsolete, the person or group is facing structural unemployment. Structural unemployment occurs when there is a mismatch between the skills that workers possess and the skills needed for the jobs available, often due to technological advancements, as in the auto industry. Another example might include aerospace engineers becoming unemployed after the downsizing of the U.S. space program in the 1970s. It's a result of changes in the economy, such as new technologies or shifts in consumer demand, leading to certain jobs becoming outdated or relocated.
