[求助]XDF练习上的一道题

XDF练习上的一道题目,哪位NN帮忙翻译一下题目并解释下正确选项的合理性,多谢!

Companies considering new cost-cutting manufacturing process 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 possiblity, constitutes the most serious disadvantage for companies of using the method above for evaluating the financial benefit of new manufacuturing processes?

ANSWER:

D Competitiors that do invest in a new process might reduce their selling prices and thus make market share away from companies that do not.

D实际指出，管理层必须动态研究问题。因为竞争对手采取了新技术，已经在成本等方面处于优势，也就是说市场竞争环境已经变化了。因此管理层不能采取题干中的方法，在假设价格、市场份额等不变的状况下，研究决定是否采取新技术。

能不能翻译一下原文的意思

我理解原文的意思是,考虑减少成本的那些公司经常把选择投资与成本,销售价格和不变的市场份额做比较(不知道对不对)

所以d中的市场份额变了,因此这种比较就没意思了

Companies considering new cost-cutting manufacturing process( 考虑减少成本的那些公司)often compare the projected results of making the investment against the alternative of not making the investment(经常将选择投资所产生的结果与不选择投资所产生的结果作比较） with costs,selling prices, and share of market remaining constant（在成本、售价、市场份额都维持不变得前提下）.

Thanks!
