Economic growth has occurred if the:Group of answer choicesInflation rate between this year and last year is zero or less.GDP this year exceeds the real GDP this year.The unemployment rate this year is above the natural rate of unemployment.Real GDP this year exceeds the real GDP of last year.

Economic growth has occurred if the Real GDP this year exceeds the Real GDP of last year.

Here's why:

1. Economic growth is typically measured by the increase in a country's Gross Domestic Product (GDP). GDP is the total value of all goods and services produced by a country in a given period.

2. Real GDP is an inflation-adjusted measure that reflects the value of all goods and services produced by an economy in a given year, expressed in base-year prices. It's a more accurate reflection of economic growth because it accounts for the impacts of inflation.

3. Therefore, if this year's Real GDP is higher than last year's, it means the economy has produced more goods and services on an inflation-adjusted basis. This is a clear indication of economic growth.

The other options you mentioned (inflation rate, current GDP exceeding real GDP, and unemployment rate) are economic indicators, but they do not directly measure economic growth.
