Answer :
Answer:
The correct answer is I. Government grants to students to pay for higher education.
Explanation:
According to economic theory, the increase of productivity is one of the most important determinants of long-run economic growth. Education has a direct impact on the ability of a society to improve productivity. Thus, when government invests in raising education standards or widening its scope, reaching an increasing amount of individuals, is creating an incentive for sustained economic growth in the long run.
The other two options might also trigger economic prosperity, but are short-term approaches.
