Up E!
Disagree with litheliluo.
If B were correct, this sentence'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. " would have been ignored.
恰恰相反,B——‘去年这种喷汽式飞机的产量至少不能低于1994年’则不是一个必要前提,because 文中未提及'产量'与'排废量下降'之关系. 是做题者self 的假设.
