Question

1. the interaction of individual choices

individuals living in the state of nebraska like to consume both soybeans and blueberries. while it is possible for farmers to grow both crops in nebraska, almost no farmers elect to use their land to grow blueberries. instead, every year, nebraska exports soybeans and imports blueberries from nearby michigan, where growers specialize in blueberries.
which of the following principles of economic interaction best describes this scenario?
when markets do not achieve efficiency, government intervention can improve overall welfare.
trade can make everyone better off.
all costs are opportunity costs.
there is a tradeoff between equality and efficiency.

Explanation:

1. Analyze the first option: The scenario has no mention of market inefficiency or government intervention, so this is not applicable.
2. Analyze the second option: Nebraska exports soybeans (which it can produce well) and imports blueberries (which Michigan produces well). This shows that through trade, both regions can get the goods they want, making everyone better off. This fits the "Trade can make everyone better off" principle.
3. Analyze the third option: The scenario is about trade between regions, not about opportunity costs in the sense of explaining the trade decision here. Opportunity cost is about what is given up, but the focus here is on trade benefits, not just cost analysis.
4. Analyze the fourth option: The scenario has nothing to do with the trade - off between equality (fair distribution) and efficiency (optimal resource use), so this is irrelevant.

Answer:

B. Trade can make everyone better off.
