C注意是output per miner, not total output.开新矿之后，output per miner还是不变的

E如果新技术的成本也很高的话，抵消了人力成本，每吨成本可高可低并不一定就低。

发现大家做题怎么总是从好的方面去想，也要想想坏的一面啊。

或者说，其实根本没必要想题目以外的东西。

看了楼上的回复，自己又想了想。觉得问题是不是出在existing，原文想表达的推理是：新技术-->导致现有煤矿产量的增加，例如T的每个矿工的产量翻了一倍（在没有新矿的情况下--这里是做一个补充说明为了使论述更严谨，其实这个完全不是此段文章想论述的内容，至于在有新矿的情况下单位产量或总产量是如何的？文章根本没有回答，自然我们无法推论出了。）故排除无关项B\C\D\E，只能选A了。

PS：最近感受，这个GWD的题目很多时候答案不是那么明确，即不是我们看了题目之后心里想到的答案，用排除法是不错的策略。

That the
application of new technology can increase the productivity of existing coal
mines is demonstrated by the case of Tribnia’s coal industry.  Coal output per miner in Tribnia is double
what it was five years ago, even though no new mines have opened.

Which of the
following can be properly concluded from the statement about coal output per
miner in the passage?

    

1. If the number of miners working in
        Tribnian coal mines has remained constant in the past five years,
        Tribnia’s total coal production has doubled in that period of time.
2. Any individual Tribnian coal mine
        that achieved an increase in overall output in the past five years has
        also experienced an increase in output per miner.
3. If any new coal mines had opened in
        Tribnia in the past five years, then the increase in output per miner
        would have been even greater than it actually was.
4. If any individual Tribnian coal mine
        has not increased its output per miner in the past five years, then that
        mine’s overall output has declined or remained constant.
5. In Tribnia the cost of producing a
        given quantity of coal has declined over the past five years.

A是个比较隐蔽的答案，arundhati，你有没有发现，conlusion的难题都是用一些抽象的词或是概括的话去代替原文中的名词，想造成是新信息的假象，使的我们一看就排除。其实就是答案，我想是老美可能就不存在这种障碍了。这题也是同样的，工人数不变就是没有开新矿的代名词。

有想像力, 可是开新厂了,总的工人数就不会增加么?  不是应用新技术了吗? 新技术还会需要那么多工人吗?

个人觉得这题有问题， BCDE 都可以排除， A 也不能保证万全。 题目中没有提到工人数， 而且工人数不变不等于工厂数也不变。

 C   .If any new coal mines had opened in Tribnia in the past five years, then the increase in output per miner would have been even greater than it actually was.

假设output per miner 原来是50 ，开了一家new coal mine，他的overall output 为800，有20个miners ，即output per miner为40，不但没有提高整体的，反而还降低了整体的output per miner。我的意思就是If any new coal mines had opened in Tribnia in the past five years推不出来the increase in output per miner would have been even greater than it actually was.

这句话可能正确也可能错误！

D 如果有miner人数不变这一条件的话，应该才对吧！

感觉我解的怎么像是数学题！

“output per miner”

感觉这个说到点子上了~
