这题A错在哪里？

问题如下：

When economic activity is at the peak level in the business cycle, there is:

选项：

a decrease in the inventory-sales ratio in many industries

a rapid decrease in inflation rate.

an increase but slowdown in hiring rate.

解释：

C is correct.

When business cycle is at the peak phase, sales growth begins to slow and unsold inventories accumulate. There is an increase in inventory-sales ratio. In terms of inflation, it continues to increase at that time.

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选项说法错误。

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选项说法错误。

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选项说法正确。
