问题如下：
The industry experience curve presents the direct cost per unit of good or service relative to:
选项：
A.output.
B.the stage of the industry life cycle.
C.age of companies.
解释：
A is correct.
The industry experience curve shows the direct cost per unit of good or service produced or delivered as a typically declining function of cumulative output. In high fixed costs industries, the increased output and scale economy lead to unit cost reduction.
A是正确的
本题考察的是书上一个比较偏的知识点，同学可以了解即可。
同学可以类比规模经济来记忆该知识点。随着产量的增加，每生产一单位产品或者服务所需要的可变成本不变，但是固定成本会下降，所以产量的增加会使该成本下降，这就是行业经验曲线所体现的。所以A正确。BC都不说直接相关的。所以不选。
考试会出这样的题吗？
