In response to mounting public concern, an airplane manufacturer implemented a program with the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division. When the program began in 1994, the division's hazardous waste output was 90 pounds per production worker; last year it was 40 pounds per production worker. Clearly, therefore, charges that the manufacturer's program has not met its goal are false. Which of the following is an assumption on which the argument depends? A. The amount of nonhazardous waste generated each year by the passenger-jet division has not increased significantly since 1994. B. At least as many passenger jets were produced by the division last year as had been produced in 1994. C. Since 1994, other divisions in the company have achieved reductions in hazardous waste output that are at least equal to that achieved in the passenger-jet division. D. The average number of weekly hours per production worker in the passenger-jet division was not significantly greater last year than it was in 1994. E. The number of production workers assigned to the passenger-jet division was not significantly less in 1994 than it was last year. 答案是E~我想问的是题目的最後这句话怎麽理解 charges that the manufacturer's program has not met its goal are false. 我是看成这个program没有达成他的目标所以是失败的 但是假如计画失败的话答案E就不合理啦~只有计画成功才可能阿~求救~~ --
