Correct Response: B. In an assembly-line manufacturing process, the unfinished products are transported along a moving belt. At different stations along the path of the belt, workers perform different steps in the manufacturing process. This eliminates the need for the nonproductive efforts of workers delivering parts from station to station as the various manufacturing steps are completed. Or, if the other choice is for one worker to perform the entire process from start to finish, this eliminates the nonproductive effort to continually switch tools for each step of the process. The assembly-line manufacturing process does not necessarily save energy (A) and in fact, the belt itself consumes energy. The amount of raw materials (C) needed for an assembly-line manufacturing process is similar to the amount needed for other processes. An assembly-line manufacturing process relies less on human inputs (D) since some of those inputs are replaced by the action of the belt.
