76.
      
Inresponse to mounting public concern, an airplane manufacturer implemented aprogram with the well-publicized goal of reducing by half the total yearlyamount of hazardous waste generated by its passenger-jet division.  When the program began in 1994, thedivision's hazardous waste output was 90 pounds per production worker; lastyear it was 40 pounds per production worker. Clearly, therefore, charges that the manufacturer's program has not metits goal are false.  
Whichof the following is an assumption on which the argument depends?
A.The amount of nonhazardous waste generated each year by the passenger-jetdivision has not increased significantly since 1994.
B.At least as many passenger jets were produced by the division last year as hadbeen produced in 1994.
C.Since 1994, other divisions in the company have achieved reductions inhazardous waste output that are at least equal to that achieved in thepassenger-jet division.
D.The average number of weekly hours per production worker in the passenger-jetdivision was not significantly greater last year than it was in 1994.
E.The number of production workers assigned to the passenger-jet division was notsignificantly less in 1994 than it was last year.

首先不太理解为什么这个归属于 相关因果模式 推理
其次 herl的解释有一点儿不懂
前提中的变化关系是: “减排计划施行          工人平均排污(危险的)减少”
结论中的因果关系是: “减排计划(因)导致工人平均排污(危险的)减少(果)”

可是题目中的原话是“the well-publicized goal of reducing by half the total yearly amount of hazardous waste generated by its passenger-jet division ”讲的是总量而不是 平均量 所以我就囧了~

还望各路大神指点!
