C.increase but slowwn in hiring rate. C is correct. When business cycle is the pephase, sales growth begins to slow anunsolinventories accumulate. There is increase in inventory-sales ratio. In terms of inflation, it continues to increase thtime.考点Business Cycle Characteristics解析经济运行在顶点的时候，销售该是减缓，存货开始挤压，所以 inventory-sales ratio应该是上升而非下降，所以A说法错误。经济运行在顶点的时候，依然会面临不小的通胀压力，所以通胀不会出现大幅下降，所以B说法错误。经济运行在定点的时候，就业率依然很高，但是增幅受限，所以C说法正确。 RT，我知道它是滞后指标，但是PEAK的上一个阶段不是扩张阶段么，那么的确是会缩小这个指标，我这样理解错在哪里呢
