问题如下：
Which of the following regarding a kinked demand curve model is least accurate?
选项：
A.Oligopolistic firm can maximize its profit at the kinked price.
B.It is a traditional model of oligopoly.
C.The price above kink is less elastic than price below the kink.
解释：
C is correct. In a kinked demand curve model, the firm will face a demand curve that is flatter above the kinked price than below the kinked price. A flatter demand means more elastic.
考点：需求弯折曲线模型
解析：在该模型上，弯折处的点可以使得企业获得最大收益，因为该点上方的需求曲线更具弹性，提价会导致更多的需求量下降从而减少总收入。而该点下方的需求曲线缺乏弹性，降价不会增长很多需求量，这也会导致总收入减少。A选项不入选。
该模型是传统垄断寡头模型中的一种，所以B选项不入选。
这点上方的曲线部分比下方的曲线部分更具弹性，所以C选项入选。
可是MR=MC的点出现了断档，那这个点取不到，还能说A是对的吗
