In 2009, the government of a nation established a price support for wheat. The government's support price has been above the equilibrium price each year since, and the government has purchased all wheat over and above the amounts that consumers have bought at the support price. Every year since 2009, there has been an increase in the number of wheat producers in the market. No other factors affecting the market for wheat have changed. Predict what has happened every year since 2009 to each of the following:
a. Amount of wheat supplied by wheat producers
b. Amount of wheat demanded by all wheat consumers
c. Amount of wheat purchased by the government
