T-3-Q33-Q36
Whereas United Stateseconomic productivity grew at an annual rate of 3 percent from 1945 to 1965, ithas grown at an annual rate of only about 1 percent since the early 1970’s.What might be preventing higher productivity growth? Clearly, the manufacturingsector of the economy cannot be blamed. Since 1980, productivity improvements inmanufacturing have moved the United  States from a position of acute decline inmanufacturing to one of world prominence.Manufacturing, however, constitutes a relatively small proportion of theeconomy. In 1992, goods-producing businesses employed only 19.1 percent ofAmerican workers, whereas service-producing businesses employed 70 percent. Althoughthe service sector has grown since the late 1970’s, its productivity growth hasdeclined. Several explanations have been offered for this declined and for the discrepancy in productivitygrowth between the manufacturing and service sectors. One is that traditionalmeasures fail to reflect service-sector productivity growth because it has beenconcentrated in improved quality of services. Yet traditional measures of manufacturingproductivity have shown significant increases despite the under measurement ofquality, whereas service productivity has continued to stagnate. Others argue thatsince the 1970’s, manufacturing workers, faced with strong foreign competition,have learned to work more efficiently in order to keep their jobs in the United States,but service workers, who are typically under less global competitive pressure, havenot. However, the pressure on manufacturing workers in the United States to work moreefficiently has generally been overstated, often for political reasons. Infact, while some manufacturing jobs have been lost due to foreign competition,many more have been lost simply because of slow growth in demand for manufacturedgoods.
       Yet another explanation blames thefederal budget deficit: if it were lower, interest rate would be lower too,thereby increasing investment in the development of new technologies, whichwould spur productivity growth in the service sector. There is, however, no dearth of technological resources, rather, managers inthe service sector fail to take advantage of widely available skills andmachines. High productivity growth levels attained by leading edge servicecompanies indicate that service sector managers who wisely implement available technologyand choose skillful workers can significantly improve their companies’productivity. The culprits for service-sector productivitystagnation are the forces-such as corporate takeovers and unnecessary governmentalregulation-that distract managers from the task ofmaking optimal use of available resources.

Which ofthe following, if true, would most weaken the budgetdeficit explanation for the discrepancy mentioned in line 27?
.A.   Research shows that the federal budgetdeficit has traditionally caused service companies to invest less money inresearch and development of new technologies.
B.   New technologies have been shown to play asignificant role in companies that have been able to increase their serviceproductivity.
C.   In both service sector and manufacturing,productivity improvements are concentrated in gains in quality.
D.   The service sector typically requires largerinvestments in new technology in order to maintain productivity growth thandose manufacturing
E.    High interest rates tend to slow the growthof manufacturing productivity as much as they slow the growth of service-sectorproductivity in the United  States.
求解释一下问什么选E .

I think  A is best answer because if A is true the service should be decreased, but actually, the service is increased now.
