９６、The following is a letter to the editor of a news magazine.
　　"Clearly, the successful use of robots on missions to explore outer space in the past 20 years demonstrates that robots could be increasingly used to perform factory work more effectively, efficiently¹, and profitably than human factory workers. The use of robots in factories would offer several advantages. First, robots never get sick, so absenteeism would be reduced. Second, robots do not make mistakes, so factories would increase their output. Finally, the use of robots would also improve the morale² of factory workers, since factory work can be so boring that many workers would be glad to shift to more interesting kinds of tasks."
