All of the following statements accurately characterize the management of American corporations in the 1920s except: men with engineering or business-school training became more prominent at the upper-management level. increasingly, top-level managers concentrated on long-range planning while leaving it to autonomous, integrated divisions to meet short-term goals. as manufacturing became more specialized, corporations divested themselves of divisions that they could not adequately control, with the result that the corporate consolidations of the 1890s and 1900s were largely reversed. General Motors set the pattern for large-scale corporate management.
