In response to mounting pubic 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?
T-3-Q16. In response to mounting public concern, an airplane manufacturers implement a program with 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 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 1984 时间段错误 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.
这道题我刚开始选的B,因为文中用per production worker生产的waste来衡量plan是否成功,但是如果去年比94年少是因为飞机的产量减少了,那么就不能说这个plan是成功的。 但是GWD答案选E。我觉得选E也有E的道理,把per production worker产生的waste减少归因于工人人数的增加,那么其实总量waste没有变,只是工人多了,分到每个工人头上的就少了,一样能削弱plan。。
