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.

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

If the original contractual price for the weapons purchased incorporated an inefficient use of funds, then, since historical costing merely adds to the original price, it preserves these inefficiencies. An economically sound pricing method should at least allow the possibility of reductions in price as such inefficiencies are removed. Hence, A is the best answer.

请高手帮忙理解下这个意思，最好有数字说明

题干：一项军火交易方案是这样： 每次买的时候都按 （历史价，即第一次购买价）* (1+inflation rate)

题目问，哪一项是反对 这项军火交易案是经济合理的， 言外之意，哪项是说它经济不合理的。

A 说政府会持续为 之前某一次低效资金使用 付出代价。

  低效资金使用对于政府来说就是 历史出价高了贝， 按议案来讲，会持续性出价高， 所以这议案不合理

这个题目不太好选，我选的是C。

看他答案的意思是，如果前一年的contratual price中GOVERNMENT已经支付的中有一部分是inefficient，那么以后每年价格都增加的话，还会有inefficient的部分。

我觉得，这题目，你得抓住economically sound来解。它表示节约的。问题就是：哪个选项说明这种定价方法是不经济的，是不节约的。

所以很明显A最能表明，这种定价方法是不经济的，不节约的。
