Frederick Winslow Taylor, a machinist and engineer who worked in the early twentieth century,
believed that the productivity of a job could be improved if one were to separate the components of
a task into its individual motions and found the best way to perform each motion, then redesign the
job so that each motion could be done as efficiently as possible.
(A) if one were to separate the components of a task into its individual motions and found the best

(B) if one separated the components of a task into individual motions, found the best way to perform
