Final answer:
An increase in the popularity of corn ethanol as a fuel increases the demand for corn, causing the price to rise. Therefore, an increase in the popularity of corn ethanol as a fuel will result in a rise in the price of corn.
Step-by-step explanation:
An increase in the popularity of corn ethanol as a fuel increases the demand for corn around the world, causing the price to rise.
This is because as the demand for corn increases, there are more buyers competing for a limited supply of corn, which drives up the price.
For example, if the popularity of corn ethanol increases, more farmers may start growing corn instead of other crops, leading to a decrease in the supply of those crops and an increase in the price of corn.
Additionally, if the demand for corn ethanol increases, more buyers will enter the market and compete for the available corn supply, further driving up the price.
Therefore, an increase in the popularity of corn ethanol as a fuel will result in a rise in the price of corn.
