哪位高人能给几个AA JJ 题的理由？多谢。

1. The following appeared in a presentation by the chief production manager of a machine parts manufacturing company at a management meeting:

“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.”

Discuss how well reasoned . . .etc.

2。某市因为工业污染严重，来这里旅游的旅客减少了很多，政府的收入相应地减少。而最近在该市一些公园发现有矿产资源，所以作者提议让一些企业能在这些公园里开采矿，这样这些企业就能赚钱并愿意支付税，这样政府就能增加税收收入

3：Due to the decline demand of the mining technology, all the realted corporations are sufferring form decline of profit and sales this year, including company X. company X is considering adopting one growth strategy: to shift some of the researchers from mining technology to the renewable energy technology, the demand for the renewable enenergy such as solar energy. Some of the prominent companies which markets the renewable energy are successful in recent years. Therefore, it is garanteed that company X will also be successful in the furture by providing renewable energy.

蓝色回忆

1、其他factories如果生产别的零部件可能效率低得更恐怖；其他factories所在地卖drill bits也许能卖个好价；把生产不同零件的machine运来运去会cost很多。

不一定只有这一个方法可以减少overall production costs，还可以通过减少labor cost等等。。

2、未必是工业污染导致游客减少

挖矿有cost，说不定大于挖矿带来的收益

这篇没有原文。。我看以前的JJ有过类似的题，好像还有提到说挖矿可以给那些曾在旅游业工作的人创造很多工作机会。那么还可以反驳说旅游业和挖矿业不能类比，那些人未必适合做挖矿工作。

3、未必是decline demand of mining tech导致corporations suffer，可能经济状况整体差

prominent companies从renewable energy中受益，未必X company也适合做renewable energy

prominent companies在recent years从中受益，未必in the future还会如此
