问题如下：
Which of the following statements regarding to fiscal deficits is most accurate?
选项：
A. Fiscal deficits may crowd out private investment.
B. Central bank has to print money to address deflationary conditions.
C. Higher government spending may lead to lower interest rates.
解释：
A is correct.
Government borrowing may divert private sector investment from taking place and this effect is called crowding out.
考点： fiscal deficits
解析：政府支出增加会产生财政赤字，进而抬升市场利率，打击私人部门投资的积极性，进而产生挤出效应。所以A选项正确，C选项错误。
面对通缩特别是流动性陷阱的状况，央行靠印发货币是解决不了问题的，正确的做法是采用量化宽松的手段。所以B选项错误。
量化宽松（QE：Quantitative Easing）主要是指中央银行在实行零利率或近似零利率政策后，通过购买国债等中长期债券，增加基础货币供给，向市场注入大量流动性资金的干预方式，以鼓励开支和借贷，也被简化地形容为间接增印钞票。 这个解释合理吗？qe也是意味着印钞票?
