<span>Real and Nominal GDP differ on what they measure. The Real GDP measures goods and services in the economy with prices adjusted for inflation, while Nominal GDP just takes the prices of the current year. The difference and the point of this would be that if one measures Nominal GDP you don't know whether the GDP went up because there were more goods and services produced or because the inflation rate went up. Real GDP measures the actual growth of the economy with adjusted prices to one similar base year. So you can see that the problem with using nominal GDP to measure the growth of the economy is that one doesn't know whether the economy grew or whether the value of the dollar just fell (aka inflation went up). Hope this helps!</span>
Answer: Irrigation
Explanation:
You included no options (unless there weren't any to begin with) but irrigation should be the answer.
Irrigation is a method of watering plants that involves controlling the amount of water that goes into a farm in a given period. It works by channelling water from a water source like rivers and wells and then directing it to farms.
People built canals from the Tigris and the Euphrates that channelled water to their farms thus enabling them to use the two rivers to water their crops. The ancient Egyptians did the same with the Nile.
