Question

in the system of mass production, unskilled workers
were hired to tend to machines and were paid more than skilled workers.
were hired to help skilled workers and were paid more than skilled workers.
were hired to tend to machines and were paid less than skilled workers.
were hired to assist skilled workers and were paid the same as skilled workers.

Explanation:

In the mass - production system, unskilled workers' main task was to tend to machines (as the production process was mechanized and required less skill for machine - tending tasks). Also, unskilled workers typically received lower pay than skilled workers because skilled workers had specialized knowledge or skills that were more valuable in terms of production complexity or quality control. So we analyze each option:

• Option 1: Unskilled workers were not paid more than skilled workers, so this is wrong.
• Option 2: Unskilled workers' role was not mainly to assist skilled workers in the mass - production system, and they were not paid more, so this is wrong.
• Option 3: Unskilled workers were hired to tend to machines and were paid less than skilled workers, which matches the characteristics of the mass - production system.
• Option 4: Unskilled workers were not paid the same as skilled workers, so this is wrong.

Answer:

C. were hired to tend to machines and were paid less than skilled workers.
