T-3-Q16,请各位帮忙

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.

 答案是B, 但D错那里了呢,per production worker 是什么意思呢

AB模式..明显的要使条件A有意义.

选B.取非削弱.

D无关吧...

目标是使总污染减一半,实施后只说每位工人产生的污染减到了40%,B说:去年飞

机产量>=94年飞机产量,那总的污染有可能并没有减少啊。

不懂

B应该是说去年的飞机产量=94年的飞机产量吧?
