Question

Quizplus · Accepted Answer

Productivity levels, or the efficiency with which a country uses its resources to produce goods and services, significantly affect a country's standard of living. Countries with higher productivity levels can generate more output, which can then be distributed among their populations in the form of higher wages, better healthcare, improved education, and other benefits.

Answer: A and C are not the best choices 
 Population size and location do not directly influence a country's standard of living. Rather, they can affect a country's productivity by influencing factors such as the availability of resources, the quality of infrastructure, and the level of human capital. However, differences in these factors do not fully explain differences in standards of living across countries.
