Answer: True
Explanation: Sociology became an important scientific discipline in the 1920's, when it began to be practically applied to improve working conditions of workers, and the ultimate goal is to increase productivity and increase profits. Many scientific theories in sociology have been presented as the results of conducted experiments and surveys with workers, which have become an integral part of work ethic, behaviour and habits. All that has been done to improve working conditions has been done through sociological studies, surveys. In this way, many useful conclusions and theories can be drawn, and even about which peoples are more inclined to work, in what working conditions, etc.
