Question

Marcel takes out student loans and works part time to put himself through college. In time, he earns an advanced medical degree and goes to work in an understaffed city hospital. Marcel's economic decisions benefit the goal of efficiency by:
1. making his own job-related decisions
2. paying back loans to reduce the debt
3. contributing to the nation's productivity
4. taking advantage of equal opportunities

Answer 1

Overall, Marcel's economic decisions benefit the goal of efficiency by "3. contributing to the nation's productivity," since this is a "win win" for both the nation and for Marcel. 

Answer 2

I believe the answer is: 3. contributing to the nation's productivity

Nation's productivity is measured by calculating the amount of values that its people give through the creation of goods or services.

When Marcel worked in city hospital, he provided services that would increase the nations' productivity.
