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.

121. Manufacturers sometimes discount the price of a product to retailers for a promotion period when the product is advertised to consumers. Such promotion often result in a dramatic increase in amount of product sold by the manufacturers to retailers. Nevertheless, the manufacturers could often make more profit by not holding the promotions.
Which of the following, if true, most strongly supports the claim above about the manufacturers’ profit?
(A) The amount of discount generally offered by manufacturers to retailers is carefully calculated to represent
the minimum needed to draw consumers’ attention to the product.
(B) For many consumer products the period of advertising discounted prices to consumers is about a week, not
sufficiently long for consumers to become used to the sale price.
(C) For products that are not newly introduced, the purpose of such promotions is to keep the products in the
minds of consumers and to attract consumers who are currently using competing products.
(D) During such a promotion retailers tend to accumulate in their warehouses inventory bought at discount; they
then sell much of it later at their regular price.
(E) If a manufacturer fails to offer such promotions but its competitor offers them, that competitor will tend to attract consumers away from the manufacturer’s product.
