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 contactual price.

which of the folllowing statement , if ture , is the best basis for a criticism of historical costing as an economically sound pricing method for military contracts?

先读题目是criticism 关于这个historical costing ,是每年都要在前一年的基础上加%的费用.题目是已经否定这个方法的,并要支持这个否定.那肯定这些每年增加的费用都是不应该的,所以政府是在白花钱.(我认为这个题目比较tricky,让人脑子转两次弯)

其他选项是可以用无关及排除去做的.
