文章就说的是:一个飞机制造公司要把每年passenger-jet division的污染排放减半。94年时,每人排放90,去年40,所以他们达到了goal. B.passenger-jet 的产量94年和去年持平 这个B简直就是一点边都挨不上。人家就是讲的要减少整个部门的污染,和生产多少有什么关系呢?打个最极端的比方,哪怕这个公司现在把这个部门歇业,不就不污染了吗,goal不就达到了吗? 如果题目改成:减少单架飞机的污染排放,那还有关-但是也不是assumption。但是现在简直就是一点关系都没有。 文章里给的条件只是和工人人头有关,我们当然就只能去找和人数有关的答案咯。这样排除D就是E了。 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? B. At least as many passenger jets were produced by the division last year as had been produced 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. |
