NO.PZ2016010802000051问题如下A firm is operating beyonminimum efficient scale in a perfectly competitive instry. To maintain long-term viability the most likely course of action for the firm is to:A.operate the current level of proction.B.increase its level of proction to gain economies of scale.C.crease its level of proction to the minimum point on the long-run average totcost curve.is correct.The firm operating greater thlong-run efficient scale is subjeto seconomies of scale. It shoulplto crease its level of proction.考点规模不经济解析有效生产规模是长期平均总成本线上的最低点。该点左边的区域被称作规模经济。现在生产规模超过了超过了它，那就再退回来，减少产量。 麻烦一下为什么选C

NO.PZ2016010802000051 为何这个beyon处应该理解为数量上超过均衡点，而不是在此点上方，如果理解为在图形的上方，左右两边的点均为beyon该如何选择？
这道题第一句话翻译成中文是啥意思我理解的是图形最低点之上的部分，包括最低点的左边和右边，而不是仅仅是右边…
