Answer: a. It allowed workers to specialize on specific tasks and become more productive.
Step-by-step explanation:
The Assembly line method of production that Henry Ford initiated at his plant was a technological game changer as it enabled workers to assemble cars faster and this mass produce Ford cars at a cheaper rate for the masses.
The Assembly line worked by putting workers at various stages of the assembly line where they would focus on installing only one or a few parts into the prospective vehicle. This way they were able to focus on that specific task, become more adept at it and thus become more productive.
