17. 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.
为什么C 对A不对

17。答案应该是D吧。(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.
因为文中说的决定是否投资，只考虑本公司的情况，完全忽略竞争对手的情况。通过与自身比较，可能决定是不投资。因为假定，价格，市场份额都保持不变。但是，如果竞争对手投资了，就可能将本公司的市场抢走。
18。approximately equal to：大约等于。要强调的论断是供领养的孩子不够，文中已说了有两百万人在等。又说，在1982年有50000个领养。如果1982年领养的数量与当年可供领养的孩子数差不多，不就等于告诉我们，1982年大约有50000个孩子可供领养。这与2000000形成巨大差额。强化了孩子不够的论断。
