The time from one economic peak to another economic peak (think roller coaster ride) is called the
economic cycle
gross domestic product
net exports

The correct answer is the Economic Cycle. The Gross Domestic Product or the GDP is the name for the value of how much your country is producing and how strong your economy is. Exports are goods that you export to other countries and sell them there. Cycle implies that it goes round and round and is how economies work, boom and bust cycles.
