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?
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.
题目分析：A说一些 nonhazardous waste，范围就不对，杀。B说jet生产数量是否和以前一样多，没提，杀。C说公司的其他部门，原文谈的就是生产部门，范围不对，杀。D说工作平均时间长短，没提。E说工人数量多少，原文说过每个工人平均的waste产出问题，那就和工人数量连上了，就好像原文说平均每小时工资，有一个选项说工作时间长短，工作时间是平均每小时工资中涉及到的概念一样。如果原文说人均消费问题，有一个选项说入住这个酒店的人数问题，这个选项沾边吗？答案是肯定的！
