问题     Population growth has long been a controversial issue in economic circles, yet, surprisingly enough, the actual study of its effects is fairly well established and universal. One advantage in studying the phenomena is that wild fluctuations of populations have occurred in history, and their resulting economic impacts have been accurately recorded for analysis and dissemination by economists of future generations. The most revealing incident, no doubt, is the case of the Black Plague.
    The Black Plague, which swept through Europe and robbed it of a quarter of its population, was a tragic event of its time, but yielded the ideal environment for retrospective study of population economics. The initial result that was observed was that, with the death of so many, the work force was horrendously reduced, leaving many to believe that productivity would plummet and resources would sit idle. By that reasoning, forecasters of the period predicted a catastrophic blow to the European economy from which full recovery was only a slight possibility.
    The result of the devastation left in the plague’s wake, however, was much different. While the labor force did indeed decrease dramatically in numbers, the efficiency of each individual worker improved, due to the lessened effects of economies of scale. Although total output dropped, output per capita actually increased, since each laborer was now producing more and there were less consumers to share the output. Also, resources did remain unused, but after an initial period of waste, the costs that those wasted resources represented lowered when businesses adapted to the situation by investing in the policy of buying less resources. Thus, the overall economic result was that workers were more productive, businesses were more efficient and there was more output per person in Europe.
    Wages rose as well, since the demand for labor far exceeded the supply. Nevertheless, despite these seemingly positive results, the net effect of the Black Plague in Europe was an almost undisputedly negative one. The per capita increases were more than offset by the aggregate loss in total product. From this, the keen economist must learn that the distinction between macro and micro levels of economics must be observed to obtain an accurate picture, especially when dealing with a central element of the economy as population.
In line 3-4, paragraph 3, "output per capita" is most similar in use to "______".
选项 A、output in individual companies
B、output compared to resources
C、each average person’s output
D、consumption compared to output
答案C
解析 属词义推断题。由output per capita所在的上下文可知，per capita和上文的eachindividual worker以及下文的each laborer是同义表达。由此可知，选项C正确。
