regard to the tribnia' coal industry question, i think i will choose "E" ."E" said the cost of producing given quatity of coal had been declined during the pass five years. that virtualy conclude all the passage. well, the meaning of the passage was, due to the adoption of new technology, tribnia' coal industry doubled the output without any new existing miners. so in other word, cost per quatity should had decreased.
Q14: 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?
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.--看了前辈的分析,还是不明白为什么C不对啊!难道不能理解C就是题目中最后一句话的conclusion么?除非是even though这个词偶理解错了。 还请NN再指教。谢谢了。实在想不通。
