７４、The following is a recommendation from the director of personnel to the president of Professional Printing Company.
　　"In a recent telephone survey of automobile¹ factory workers, older employees were less likely to report that having a supervisor² present increases their productivity. Among workers aged³ 18 to 29, 27 percent said that they are more productive in the presence of their immediate⁴ supervisor, compared to 12 percent for those aged 30 or over, and only 8 percent for those aged 50 or over. Clearly, if our printing company hires mainly older employees, we will increase productivity and save money because of the reduced need for supervisors⁵."
