2. Which of the following are key components that determine a country's position on the Human Development Index (HDI)? A. Gross National Income (GNI)military strength, and life expectancy B Environmental health, military spending and infrastructure development Political stability, healthcare quality and agricultural productivity D Life expectancy, education level and income

The correct answer is D. Life expectancy, education level, and income.<br /><br />The Human Development Index (HDI) is a composite index that measures a country's overall development based on three key dimensions: life expectancy, education level, and income.<br /><br />1. Life expectancy: This measures the average number of years a person can expect to live, indicating the overall health and well-being of a country's population.<br /><br />2. Education level: This assesses the level of education and knowledge within a country, typically measured by the average years of schooling for adults and the expected years of schooling for children.<br /><br />3. Income: This reflects the economic well-being and standard of living in a country, usually measured by Gross National Income (GNI) per capita.<br /><br />These three components together provide a comprehensive picture of a country's human development, rather than focusing solely on economic indicators like military strength or infrastructure development.
