A. $Q_1$
B. $Q_2$
C. $Q_3$
D. $Q_2$$Q_3$


参考答案:  A


本题详细解析:
A

A non-binding price floor$\text{—}$a minimum price set below the equilibrium price (P${}_1$)$\text{—}$would have no effect on the market. Therefore, the quantity demanded associated with that price (Q${}_1$) would still be the quantity demanded after the imposition of the minimum price.

Choice B is incorrect as Q${}_2$ would be the quantity supplied had the question been about a maximum price.

Choice C is incorrect as Q${}_3$ would be correct if the question was about a maximum price.

Choice D is incorrect as Q${}_2$Q${}_3$ would be the shortage caused had the question been about a maximum price.
