46.
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.


这是答案（刷）：D
为什么啊 ？HELP~THX~

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.
公司对于上述两种措施进行比较。题目是寻找评价新过程的disadvantage。
A。新过程的成本未知。
B。利息下降，导致所借的投资款的利息下降。
C。新过程不能立即净利润。
D。新过程可以降低产品售价，抢占市场份额。
E。平均投资成本的时间会对结果产生影响。

一个是成本下降，默认收入和投资的综合不会下降。
另一个是投资减少，默认收入和成本不变。
C的话，揭示了上一个方案的假设不成立。

个人理解：
题目中比较投资与否的指标：with costs, selling prices, and share of market remaining constant.题目假设三者都不变，但事实上只要有生产者采用cost-cutting manufacturing processes，其生产成本降低，在保证利润不变的情况下可以降低价格，降价导致其市场份额上升，其他竞争者被迫降价与之竞争，否则无法挽回被夺走的市场份额。 这个是一个动态变化过程，总之就是高中政治学过的：通过技术革命降低生产成本可以增加产品竞争力。
