标题: 新东方蓝皮书61，71变态题求解

61. An electric-power company gained greater profits and provided electricity to consumers at lower rates per unit of electricity by building larger-capacity more effecient plants and by stimulating greater use of electricity within its area. To continue these financial trends, the company planned to replace an old plant by a plant with triple the capacity of its largest plant. The company 's plan as described above assumed each of the following EXCEPT:

(A) Demand for electricity within the company 's area of service would increase in the futrue.

(B) Expenses would not rise beyond the level that could be compensated for by efficiency or volume of operation,or both.

(C) The planned plant would be sufficiently reliable in service to contribute a net financial benefit to the company as a whole.

(D) Safety measures to be instituted for the new plant would be the same as those for the plant it would replace.

(E) The tripling of capacity would not result in insuperable technological obstacles to efficiency.

答案是D，搞不懂，安全措施相同不正说明加大PLANT后成本不会增加吗？那这种假设为什么不合理

71. One state adds a 7 percent sales tax to the price of most products purchased within its jurisdiction. This tax, therefore, if reviewed as tax on income,has the reverse effect of the federal income tax: the lower the income , the higher the annual percentage rate at which the income is taxed.

The conclusion above would be properly drawn if which of the following were assumed as a premise?

A) The amount of money citizens spend on products subject to the state tax tends to be equal across income levels.

B) The federal income tax favors citizens with high incomes, whereas the state sales tax facors citizens with low incomes.

C) Citizens with low annual incomes can afford to pay a relatively higher percentage of their incomes in state sales tax, since their federal income tax is relatively low.

D) The lower a state's sales tax, the more it wil tend to redistribute income from the more affluent citizens to the rest of society.

E) Citizens who fail to earn federally taxable in come are also exempt from the state sales tax.

答案是A 众所周知这是一道很变态的题，所以恳请各位NN给予解释。

61只能是D

ABCE取非都是会削弱结论的

D即使使用不同安全措施也未必是增加成本。除非再有个前提，老厂的安全措施是最低价的。

对消费统一增收7%的税

结论说，会造成:收入低的人，征税的比例高

有个前提呀，除非大家的消费都是一样的，

否则

富人消费的多，那么其实7%的基数也就大，要交的税就多，所占比较也就多。

穷人消费少，那么7%的基数就小，要交的税就少，那么所占的比重也就小。

多谢楼主，可是考试时如果每个选项都取非看是否削弱的话，不是太费时间了。。。

恩，如果第一感觉比较迷茫的话，全部取非，是有点费时间的说

老美对61D选项的解释是..Safty measures不是硬件设施,非硬件类东西..貌似对成本影响不大

狒狒讲过，超难的题答案是A。屡试不爽。

但，前提是你眼中的难题是真正意义上的难（高分）题。
