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.（D）

(E) The period of year chosen for averaging out the cost of the investment might be somewhat longer or shorter, thus affecting the result.

题目说要weaken那个method above for evaluating the financial benefit of new manufacturing processes,我觉得A和d都是将来不确定的因素,都会weaken那个评估方法,为什么a不是答案呢

请赐教,谢谢

还有题目中说costs, selling prices, and share of market remaining constant.那么我们就丛这三个方面去找答案.可是那个cost是指manufacturing processes 的成本还是总体成本(包括为了那个投资而借的利息成本),如果是后者那么 b也是对的了我认为.

我的思路是否正确啊?

我是这样理解的

  文中是说在cost，selling price和  market share都不变的情况下，比较两个方案。如果要削弱，

   就要削弱前提。（反驳前提是最好的削弱，好象XDF的老师这么说过）那么，在这题中，就要从上面三个方面选则，进行前提反驳。也就是D答案所说的了

语言比较混乱，不知道楼主能不能看懂

哦.我看错题目意思了

cost，selling price和  market share都不变,我以为是从那三个方面来评价投资的好坏
