AAB8大家帮忙看看这篇JJ的逻辑错误，明天考试了谢谢~

“Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.”

请大家帮忙提供下思路，谢谢~

1. 缺乏足够的证据证明Our factory in Cookville is our most advanced and efficient.

2.降低单个机械零件的生产成本不是achieve our larger goal of reducing our overall production costs的唯一方法,可以降低其他成本,如劳动力成本

3.降低单个机械零件的生产成本不是achieve our larger goal of reducing our overall production costs的充分条件,有可能原料成本的上涨抵消了单个机械零件的生产成本的下降

帮你修改了下标题，参考下面贴子里的AAB8

1 not the only way: labor cost

2 move will cost a lot: long distance=high cost

3drill bits is not main product, another is. Other factories don’t have production line for it.
