Think about all the ways the slaughterhouses’ moving assembly lines could help Ford’s business. Check all the statements that apply.

A moving assembly line lets each worker repeat one specialized task, so workers need less training in many different jobs; this makes D correct. Bringing the car to the worker, as in C, also reduces time spent moving around. Faster, more efficient production lowers Ford’s costs and can make cars less expensive, so B is correct. The line would not require more highly skilled workers or make production slower.
