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?

 

1. the amount of nonhazardous waste generated each year by the passenger-jet division has not increased significantly since 1984

2. at least as many passenger jets were produced by the division last year as had been produced in 1994

3. 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.

4. 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.

5. The number of production workers assigned to the passenger-jet division was not significantly less in 1994 than it was last year.

个人还是选E,但是答案是B.

奇怪啊

我觉得E就是排除他因啊,如果94年员工少于去年,

总排放/员工数=每人排放

则也许94年和去年的总排放相同呢,

答案應該是E吧

總量/worker =hazardous wast per production worker

worker 越少= hazardous wast per production worker 越多, 反之亦然-->所以該是E

正确答案就是选E
