Companies considering new cost-cutting manufacturing processes often compare the projected results of making the investment against the alternative of not making the investment with costs, selling prices, and share of market remaining constant.
Which of the following, assuming that each is a realistic possibility, constitutes the most serious disadvantage for companies of using the method above for evaluating the financial benefit of new manufacturing processes?
(A) The costs of materials required by the new process might not be known with certainty.
(B) In several years interest rates might go down, reducing the interest costs of borrowing money to pay for the investment.
(C) Some cost-cutting processes might require such expensive investments that there would be no net gain for many years, until the investment was paid for by savings in the manufacturing process.
(D) Competitors that do invest in a new process might reduce their selling prices and thus take market share away from companies that do not.
(E) The period of year chosen for averaging out the cost of the investment might be somewhat longer or shorter, thus affecting the result.
Ket:d,why not c?
Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it. The trade of businesses selling and renting videos is still buoyant, because the number of homes with video recorders is still growing. But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.
Which of the following, if true, would most seriously weaken the conclusion above?
(A) The market for video recorders would not be considered saturated until there was one in 80 percent of homes.
(B) Among the items handled by video distributors are many films specifically produced as video features.
(C) Few of the early buyers of video recorders raised any complaints about performance aspects of the new product.
(D) The early buyers of a novel product are always people who are quick to acquire novelties, but also often as quick to tire of them.
(E) In a shrinking market, competition always intensifies and marginal businesses fail.
Key:d.能不能解释一下这题?

1. with costs, selling prices, and share of market remaining constant是需要满足的条件，也是文中唯一提到和method相关的内容，所以d对。C 选项好像无关吧。

2."（只有）early buyer是喜新厌旧之人（将来的buyer不一定就过6个月不租video了）"  它因 来weaken题干中的推理。

Sunder,
Sorry that I can't agree on your first explanation. First, the method is to compare the projected results of making the investment against the alternative of not making the investment. Secondly, costs, selling prices, and share of market remaining constant are the parameters used in the method.
Choices A, B, C and E are all related with the accuracy of the method. But only D points out that the foundation of the method is wrong. It should compare the company considering new process with the company's rival in the same situation.
Discussion is very welcome!!!
