问题如下：
Which of the following terms refers to the situation when the government has to print more money and people are eager to change their cash into real goods and the rate of price increase accelerates?
选项：
A.Hyperinflation
B.Disinflation
C.Deflation
解释：
A is correct.
Hyperinflation usually occurs when government increases the money supply, and people are eager to change their cash into real goods because prices are rising very fast.
考点：Hyperinflation
解析：当发生超级通货膨胀时，政府会加速印发货币，这时货币不值钱物价上涨进一步恶化，为此人们囤货意愿迫切，都捉急把货币转换成商品。所以A选项正确。
无论是发生 Disinflation 还是Deflation，都表明通胀情况得到了控制，此时人们把货币 转换成商品的意愿就没有那么强烈了。
hyperinflation为什么要加速print money？ 那样钱不是更不值钱了吗
