A six-membered ring structure where nitrogen is labeled one and is connected to a hydrogen atom, carbon is labeled two and is a ketone, nitrogen is labeled three and is double bonded to the carbon labeled four. Carbon four is attached to NH2, and the carbons labeled five and six are double bonded to each other. A heterocyclic molecule with two fused rings, a six-membered and a five-membered ring that share carbons four and five. The rings have four nitrogen atoms at positions one and three of the six-membered ring and positions seven and nine of the five-membered ring. Carbon two is attached to an amine group and carbon six is double bonded to an oxygen atom.

As a result of the income of college students suddenly rising, we should expect the price of Gnarly Barley beer (a "normal good") to rise and the quantity supplied and demanded to fall as Zac's profits rise in the short run. An increase in consumer's wealth and income has no effect on market demand or market prices. In the long run, what should we expect to happen to the price of all of Zac's "inputs" (his costs of producing beer, including the cost of paying workers, buying raw materials like barley, building new facilities, etc.) as this newly printed money spreads throughout the economy? The price of these inputs will rise and Zac's profits will fall. Changes in the money supply don't affect relative prices or distort market price signals at all. Zac's decision to rapidly increase beer production following this monetary surprise *best* illustrates which of the following problems created by inflation?
