| Society was fascinated by science and
things scientific in the nineteenth century. Great breakthroughs in engineering,
the use of steam power, and electricity were there for all to see, enjoy, and
suffer. Science was fashionable and it is not surprising that, during this great
period of industrial development, scientific methods should be applied to the
activities of man, particularly to those involved in the processes of
production. Towards the end of the nineteenth century, international competition
began to make itself felt. The three industrial giants of the day, Germany,
America, and Great Britain, began to find that there was a limit to the
purchasing power of the previously apparently inexhaustible markets. Science and
competition therefore provided the means and the need to improve industrial
efficiency. Frederick A. scientific and human B. efficient but slave-driving C. academic but practicable D. brutal but highly successful [单项选择]
