Answer:
Explanation:This scenario best describes the principle of "Trade can make everyone better off."
In this case, Nebraska farmers specialize in growing soybeans and exporting them, while Michigan farmers specialize in growing blueberries. By specializing in what they are good at and trading with each other, both states can benefit from the exchange of goods. Nebraska gets to consume blueberries without having to use resources to grow them, and Michigan gets to consume soybeans without having to use resources to grow them. This allows both states to produce more goods and services than they could if they tried to grow everything themselves. By trading with each other, everyone is better off.
