问题 Within the last fifty years, the majority of the United States work force has moved from the manufacturing to the service sector of the economy. This shift has occurred, not because of a decline in the production of goods, but because, with applications of new technology, more production of goods can now be achieved with relatively fewer people, and more people are therefore available to satisfy the increased demand for services. Which of the following, if true, provides evidence to support the claim made above that more production of goods can now be achieved with relatively fewer people?
选项 A、Many manufacturing industries in the United States have lost a significant share of their domestic and foreign markets to foreign producers.
B、Services accounted for half of all jobs in the late 1940’s but today account for seventy percent of all jobs.
C、Manufacturing output was one-third higher in 1980 than in 1970, while manufacturing employment grew only five percent during that period.
D、Manufacturing industries, on average, pay a higher per-hour wage and use fewer part-time employees than do service industries.
E、Living standards in states that have shifted to manufacturing economies within the last fifty years are closer to the national average now than in 1940.
答案C
解析 本题支持的内容非常明确，已在问题目的中清晰列出，即让我们找一个选项说明确实“更多的物质生产可由相对较少的人完成”，读完问题目的马上可以理解答案内容。(C)说明1980年比1970年高出1／3，而就业人数只高出5％，实现了问题目的，所以(C)正确；(B)易误选，但(B)并不能表明“更多的物质生产可由相对较少的人完成”；(A)、(D)、(E)均无法实现问题目的。
