Explanation:

Opportunity costs in economics, also known as the alternative forgone is defined as the value or benefits of what an individual or business entity has to give up in order to choose something else that's desired. This simply means that, when an individual or business entity chooses one alternative over another, they miss out on other benefits or valuable profits.

Examples of opportunity costs are;

1. Taylor giving up going to the cinema to see a comedy movie, to study for his final exams in order to pass with distinctions. The opportunity cost here, is the cost of the comedy movie and the satisfaction associated with seeing it.

2. Messi attends football training in order to become the world's best player instead of taking a vacation to Las Vegas. The opportunity cost here, is the vacation.

it requires the president to notify congress within 48 hours of sending armed forces to military action.
