Answer:
moving assembly line
Step-by-step explanation:
Henry Ford needed a fast way so make and produce cars, so he invented the assembly line, where the car was moving on a conveyor and the employees each had one specific job to put on the car, for example one person would put the wheel on, all day, and people down the line might bolt the wheel into place, but the one guys job is just to put the front right tire on the cars, all day, every day. This let Henry Ford mass produce cars, and get thousands of cars into peoples possessions.
