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

个人感觉答案是E

E选项取非，说明人数比前一年减少，他因削弱，not+weaken型

结论：说这个program没有达到目标的控诉是错误的！理由：人均浪费从90下降到40.但是这里有一个问题，如果总量浪费更多了，只是由于这个部门的人数大大增加，才导致的人均下降，那么这个program无疑是没有达到预期效果的。所以E排除了这个可能，即该部门人数没有大幅增加~

我也支持E~~~

A.     The number of production workersassigned to the passenger-jet division was not significantly less in 1994 than it was last year.（原文的goal是要减少总量total amount，而给出的evidence是单位数量per production worker，所以要使总量减少，而单位数量能说明问题的情况下，数量要保持不变）
