下面这题让我百思不得其解，我不懂contractual price,和最后一句的"to the previous..." should connect the "increase" or the "rate of a to b" 该公式应该是？
30. 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.

政府用的计价方法是：在以前的合约上的价格上加上一个通货膨胀率。这样的话，如果以前的定和约时的价格太高了，现在还是会继续这个高价，这样政府使用资金的就不是最有效率的。也就是说，不管以前的价格怎样，现在继续。当然有可能造成不合理的情况的啊
