能不能具体谈谈此题目的解题思路？

新东方的方法用处的不大呀。

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.

购买费= 历史价+通货膨胀。 不合理 =》购买费高。 等式成立，则历史价+通货膨胀 的和也增高。两种可能：1）历史价本来就算多了
                  2）将通货膨胀率算多了。
答案：A
其实这题用排除法，更好做

赞成，通俗的说就是原来有定价就有可能不合理，而政府改变不了，还得继续付，政府好亏啊。

多谢多谢！
不过这个题目用排除法该怎样做呢？
不好意思，我的逻辑是verbal里最差的。

这题是要说在经济上，历史定价法会产生什么不利影响。
D.E.先排除，不是从经济上考虑的。
C.受原材料价格影响。那又怎样？会对政府或军火商不好吗，不一定
B.过去通胀率变化很大。那又怎样？过去通胀率高，多支付点，过去通货紧缩，少支付点，
挺合理的
