GWD-1-14 That the application of new technology can increase the productivity of existingcoal mines is demonstrated by the case of Tribnia’s coal industry. Coal outputper miner in Tribnia is double what it was five years ago, even though no newmines have opened.

Whichof the following can be properly concluded from the statement about coal outputper miner in the passage?

这种题很简单，原文没有做什么推理，所以被叫做陈述（statement），一般只要我们列出原文的条件然后把每个选项检验一下就好。这道题没什么好讲，选A就好。

A. Ifthe number of miners working in Tribnian coal mines has remained constant inthe past five years, Tribnia’s total coal production has doubled in that periodof time. 每个人生产效率提高一倍，所以如果人数保持不变那产量肯定会提高一倍的。

B. Anyindividual Tribnian coal mine that achieved an increase in overall output inthe past five years has also experienced an increase in output per miner.

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

D. Ifany individual Tribnian coal mine has not increased its output per miner in thepast five years, then that mine’s overall output has declined or remainedconstant.

E. InTribnia the cost of producing a given quantity of coal has declined over thepast five years.
