14.   The
price the government pays for standard weapons purchased from military
contractors is determined by a pricing method called “historical costing.”
Historical costing allows contractors to protect their profits by adding a
percentage increase, based on the current rate of inflation, to the previous
year’s contractual price.

    

Which of the following statements, if
true, is the best basis for a criticism of historical costing as an
economically sound pricing method for military contracts?

    

(A) The
government might continue to pay for past inefficient use of funds.

    

(B) The rate of
inflation has varied considerably over the past twenty years.

    

(C) The
contractual price will be greatly affected by the cost of materials used for
the products.

    

(D) Many
taxpayers question the amount of money the government spends on military
contracts.（A）

    

(E) The pricing
method based on historical costing might not encourage the development of
innovative weapons.

    

19.   Recent
estimates predict that between 1982 and 1995 the greatest increase in the
number of people employed will be in the category of low-paying service
occupations. This category, however, will not increase its share of total
employment, whereas the category of high-paying service occupations will
increase its share.

    

If the estimates above are accurate, which
of the following conclusions can be drawn?

    

(A) In 1982
more people were working in low-paying service occupations than were working in
high-paying service occupations.

    

(B) In 1995
more people will be working in high-paying service occupations than will be
working in low-paying service occupations.

    

(C) Nonservice
occupations will account for the same share of total employment in 1995 as in
1982.

    

(D) Many of the
people who were working in low-paying service occupations in 1982 will be
working in high-paying service occupations by 1995.（A）

    

(E) The rate of
growth for low-paying service occupations will be greater than the overall rate
of employment growth between 1982 and 1995.

第1题你应该对CDE没怀疑吧,先踢掉了,题目中的计算方法的缺陷在于adding a percentage increase, based on the current rate of inflation, to the previous year’s contractual price.这就导致政府一年花的钱比一年多...因为他要是按去年的加通涨率高低都是越来越贵.

第2道要搞一点,CDE先踢了没疑问吧,然后是数字增加比例不增加这点应该没问题,就是1982年的情况怎么推,This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share.可能是减少了share或者不变,如果LP的基数比HP小,而LP的比例却是减少或是不变,也就是最大值是不变,本来82年就比你少,比例还没变或比你小,那LP增加的数字就不可能比HP大,所以只有82年的LP人数比HP多,才有可能在share不增加的情况下number有greatest increase
