Which of the following best describes assembly-line production? a. a process using interchangeable parts that constructed products entirely instead of by individual piece b. a process using workers to construct products more efficiently by dividing labor into specialized tasks c. two or more lines of workers that simultaneously constructed products in order to reduce labor time d. a line of workers who provided quality assurance by inspecting every product assembled on the line

The correct answer is B. The assembly-line production is a process using workers to construct products more efficiently by dividing labor into specialized tasks.

An assembly line is generally constituted by a belt, called a conveyor belt, which slides carrying the different objects to be assembled to obtain the finished product; each worker can thus assemble a single piece, through repetitive and mechanical movements, allowing a considerable saving in production times: since this method went into operation, in the Ford factory, the time needed to produce a single car was reduced by 12 hours to just 1 hour.
