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? A. 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. B. 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. 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. D. 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. E. In Tribnia the cost of producing a given quantity of coal has declined over the past five years.

Which of the following, if true, most strongly supports the prediction that the plan will succeed? 22

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
