5-14.       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.

请问为什么C不对呢，不知道我读题有没有问题，我理解是本身生产weapon的成本提高了，所以本能单靠inflation来定价，请高人指点

7-16.       The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotas will help “mini-mills” flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.

Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?

(A) Quality rather than price is a major factor in determining the type of steel to be used for a particular application.

(B) Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills.

(C) American quotas on imported goods have often induced other countries to impose similar quotas on American goods.

(D) Domestic “mini-mills” consistently produce better grades of steel than do the big American mills.（E）

(E) Domestic “mini-mills” produce low-volume, specialized types of steels that are not produced by the big American steel mills.

B为什么不对呢，如果国外的mill和big american的mill生产的东西质量一样，那为什么big american不能受利，反而small mill受利了
